Strong piercing winds are not uncommon in our country. But experts managed to find the windiest place in Russia. All the coldest and windiest places in Russia are located in the eastern part of our large country.

Surely there is not a single inhabitant of Russia for whom the wind would be a surprise. Even if it is strong and penetrating. Of course, Russians from the southern regions are much less likely to encounter such a phenomenon. But the inhabitants of the central part of the country with the advent of autumn feel the severity of the Russian weather. Even more "gets" from the wind cities located in the east.

Specialists even conducted a study on the windiness of certain regions. As a result, they managed to make interesting discoveries. So the most windy place in Russia was discovered. They turned out to be Chukotka. To be more precise, this is a small town of Pevek. It is in this place that gusts of wind can reach 40 meters per second. Quite an unpleasant occurrence. Although, according to polls, residents of this city have long been accustomed to such a wind and note that the main thing is to dress according to the weather. With warm clothes made of dense, windproof fabric, such problems are not terrible. Especially today in stores you can easily find stylish and high-quality jackets-"windbreakers" for every taste.

The unprecedented windiness of the Chukotka city is quite easy to explain if you study the features of its climate. This place from time to time is subject to the strongest south wind that falls on it from the coastal hills. Interestingly, it is almost impossible to predict the occurrence of this phenomenon. The wind begins to blow quite unexpectedly and suddenly. In the cold season, strong snow whirls also form. When the wind speed reaches its maximum (which is 40 meters per second, as noted above), the citizens are advised to go outside, only observing the rules of caution. If there is such an opportunity, then it is better to stay at home during the specified period.

After all, in parallel with the appearance of wind, atmospheric pressure drops sharply. And its speed in gusts can reach 80 meters per second. Most often, severe icy weather lasts no longer than 3-4 days. But there were cases when it persisted for 15 days. All this time, the inhabitants of Pevek refused to walk, hid light things from the streets that the wind could carry away, and also did not let pets into the yard.

It is extremely difficult to understand exactly when a gusty wind (its name is "Yuzhak") will arise, but there are some signs by which one can determine its approach. For example, before that, small cumulus clouds become noticeable over the tops of the mountains. But in general, even experienced weather forecasters are not able to predict the described change in the weather.

There are other windy places in Russia. For example, residents of the northern capital experience this phenomenon almost daily. Of course, in St. Petersburg the wind is less strong and gusty.

Experts managed to determine which place in Russia turned out to be the most windy. Today, the Chukotka city of Pevek occupies a leading position in the ranking. But research on the topic under discussion is still ongoing.

Where does the wind come from: experiments, cognitive stories, speech exercises, cartoons for children. Logical tasks of Leo Tolstoy for children about the wind.

Today, with the help of entertaining experiments, you will learn where the wind comes from, and also get acquainted with how L.N. answered this question to children in 1875. Tolstoy. To be continued in the next article!

Where does the wind come from: experiments for kids

Ships (experiment-game for children 3-4 years old)

Take a bowl of water. Make paper boats. How to make boats, you will see in this video.

This is a scheme for making a paper boat for experience.

Put the boats on the water. Blow on them with your child. Why did the ships sail? (The wind pushes them.) Where did the wind come from? We exhaled air.

Arrange a ship competition. Which boat will swim to the other side faster (for this you need to take a square-shaped basin or a baby bath). Ask the baby how to blow so that the boat sails quickly?

Try to make a different wind - a soft and light breeze, a strong hurricane, a ferocious storm.

Ships for this game can be made not only from paper, but also from walnut shells. Using plasticine, attach a stick with a sail to the shell (a paper sail on a toothpick stick will do). Get on the sail. How do you blow to make the boat float?

Read to the kid the lines about the wind A.S. Pushkin.

Fan (for children 4-5 years old)

Make a fan out of a strip of paper by folding it into an accordion shape. Or take a ready-made fan. Have your child wave the fan in front of their face. What does he feel? What is the fan for? (in hot weather, the fan gives us a breeze that cools and helps us). Now let the kid try to wave the fan over the water. What happens to the water in the basin? Where did the waves come from?

Ask your child a riddle the next day. Ask why the riddle says “The wind blows - I don’t blow” (because it’s already cool and people don’t use a fan).

Sea battle (for children 4-5 years old)

What can happen to ships if there is a strong wind? (They may drown). Invite your child to make paper boats and play sea battle. They play this game in pairs. You need to blow on your own and others' boats in order to sink enemy ships. You can blow both simultaneously and in turn.

After the game, ask the child how to blow to make the wind stronger (take in more air, exhale it stronger and sharper).

Where is warmer? (for children 5-6 years old)

This experience will help to find out what is easier - warm air or cold air.

1. Let's try to figure out where the room is warmer and colder - on the floor or on the sofa (higher or lower). You can take a thermometer and measure the temperature and compare. You can hold your hand near the floor (next to the door) and at the top.

2. Then invite the child to hold his hand over the battery and under the battery. Where is warmer?

3. And you can also take a thin piece of paper (napkin) or cotton wool. Attach the top end of the strip of paper to the wall above the radiator (can be attached with duct tape or Uni patafix). At the same time, open the window above the battery. Warm air will rise up, and the piece of paper will begin to move and rise upwards.

4. We conclude that it is always warmer at the top. And this means that warm air is lighter and it rises.

5. Ask the child: “Where do you sleep? Yes, in bed. It is now so arranged that children and adults sleep in beds. after all, it is warm in our city houses. And before, when there were no batteries, children and old people slept on the beds. Polats were located high above the floor and were arranged between the stove and the wall of the house. There was not one sleeping place on the beds, but many at once - several people slept on them nearby. Why did they sleep on the floors? (it was warm there even in winter, because the beds are at the top, where the warm air is)

Where does the wind come from - an experience for children 5-6 years old

The experience was developed by O.V. Dybina.

1. You will need a candle and a snake. The snake is very easy to make:

take a circle of thin paper and cut it in a spiral, then hang the resulting blank by the thread.

• Light a candle and blow on it. Why did the flame deflect? (blowing air).
• Place the snake over the candle flame. What's going on with the snake? She will start to spin. Why is she spinning? Because warm air goes up and lifts the snake.
• You can try to have the children do this experience themselves, but not with a candle! You need to hold the snake over a hot battery.

2. Go to the door (for example, leading to a glazed balcony) and try to determine where the wind is blowing at the top of the doorway (above) and near the floor (below). In order to determine which direction the wind is blowing, you can put two candles - below and above - and see where their flame deviates. Or take a thin napkin or cotton wool and bring it to the door. Where will she go?

3. Why does the wind blow in different directions? It turns out that at the top the air is escaping from the room to the outside. This is warm air. He goes outside. And cold air is heavier and it is at the bottom. He enters the room from the street. So it turns out "wind" in the room. But that's how wind works in nature.

Turns out, Wind is the movement of air! Warm air moves up and cold air moves down, and they tend to swap places.

4. You can draw with arrows where the wind blows in the room. The red arrow at the top of the doors will indicate warm air. And the blue arrow at the bottom is cold air.

5. If there is a draft in your room, and you often ask your child not to sit on the floor near the door, then remind him of this. Ask why you are asking him not to do this? Now he already knows what caused your request and will relate to its implementation in a completely different way!

Note: do not overload a preschooler with knowledge about physical phenomena that are still inaccessible to understanding, and say that atmospheric pressure distribution plays an important role in the appearance of wind. For a preschooler, such a short answer to his question “Why is there a wind” is quite enough. But the student can already explain other reasons associated with the appearance of a different type of wind. What kind of wind is and why it happens, you will see in this video for older children - school age.

Spinner experiments

Make a spinner with your child and take it for a walk. Show how to play with a turntable. Ask the child why she is spinning? (the wind hits its blades and it starts spinning). Observe with your baby when the spinner spins fast and when it spins slowly, and why does this happen?

How to make a spinner to play with the wind

The spinner is made of paper, thick foil or a sheet of thin plastic (folder, gift wrap or paper). How it can be done, you will see in the video.
http://youtu.be/YtnQqLNh1D0

And this is a scheme for making a turntable.

Experience "Wind in the Desert"

An experience game can be played in a sandbox or pour sand into a basin. Level the surface of the sand. And then invite the child to become the wind and blow on the sand. On the surface of his "sand desert" sand waves will begin to appear. If you continue to blow, then the sand will move from one place to another and you will get hills. Let the child try to make "dunes" - sandy hills. So the wind helps the sand to travel through the desert.

Let's discuss. Is wind good or bad? Why?

It is very important that already at preschool age the child understands that not everything is so simple in the world, and in every phenomenon you can find good and bad sides. Important. so that he could think independently, could explain his point of view. These skills do not develop by themselves, but in communication with an adult who poses problematic questions with an ambiguous answer to the child.

Let's reason together.

Why is wind good? Because in the summer in the heat, when the wind blows, it is not so hot. Because the wind blows the sails and the ships can sail. Because the wind spreads the seeds of plants, with the help of the wind you can fly in a balloon, fly kites. The wind helps windmills and windmills to work.

Why is wind bad? If the wind blows in cold winter, you freeze. At sea, in a strong wind, there is a storm, and ships can sink. A strong storm can destroy houses and uproot trees. The wind carries the seeds of not only useful plants, but also weeds.

Speech exercise "What is the wind like?"

Pick up with your child as many words as possible that describe what kind of wind it is. With the help of such exercises, you will not only enrich the child's vocabulary, but also teach him to be attentive to the choice of words and notice interesting figurative words in stories and fairy tales.

What wind? He gets strong. How to say differently? Violent, fast, furious wind, dashing, frantic, assertive, merciless, impetuous, ferocious, whistling, impetuous, terrible, hurricane, squall, furious, powerful, restless, penetrating, cold, evil. fierce, angry, nasty, mournful, gloomy, terrible, icy.

And it happens the other way around - what kind of wind? Yes, weak, light. How to say differently? Gentle, quiet, warm, cheerful, southern, spring.

Now let's pick the words, what does the wind do? It blows, howls, makes noise, whistles, shakes trees, disperses clouds, drives leaves, brings sounds to us.

What is the name of light breeze? Breeze. What if the wind is strong? Windy. What if it's very strong? Storm, hurricane, storm, tornado.

How to conduct speech exercises for the selection of words?

I love to do such exercises with children on the selection of words in the form of a game. For example, if we play with words in winter, we help the wind cover the earth with snowflakes. One word is one snowflake! And you need to cover a lot of the land shown in the picture! So we select words for a very long time, because we cannot allow a bush or a flower to freeze without snow! We picked up the word - put a paper snowflake on our winter landscape. One more word - they put the second snowflake and so on until we cover the whole earth. I suggest the most difficult, rare words, children say more common words.

If we play in the fall, then we help the wind to pluck the leaves or transfer the seeds. You can come up with any game situation. In such games, the child sees the result of his efforts and therefore seeks to pick up as many words about the wind as possible. I am always surprised, but this is a fact - children remember exactly where THEIR snowflake or leaf, which they helped the wind and what exactly covered their snowflake, even if the game is played in a large group of kids!!!

I call this method of work “the visual result of speech”. If you just pick up a lot of words, then the children do not understand the meaning - why this is necessary, and they get bored. And when they complete a game task with a result that can be seen, felt, they become interested! The rich vocabulary that children receive as a result of such exercises is oh so necessary both at school and in life!

How children were introduced to the wind in the 19th century

Informative stories for children about the wind by Leo Tolstoy. The second Russian book for reading - 1875

Why there is wind (reasoning)

Fish live in water, but humans live in the air. The fish cannot hear or see the water until the fish themselves move, or until the water moves. And we also do not hear the air until we move or the air does not move.

But as soon as we run, we hear the air - we blow in the face; and sometimes you can hear when we run, how the air whistles in our ears. When we open the door to a warm upper room, the wind always blows from below from the courtyard into the upper room, and from above it blows from the upper room into the courtyard.

When someone walks around the room or waves a dress, we say: “he makes the wind”, and when the stove is heated, the wind always blows into it. When the wind blows in the yard, it blows for whole days and nights, sometimes in one direction, sometimes in the other. This happens because somewhere on earth the air becomes very hot, and in another place it cools down - then the wind begins, and a cold spirit comes from below, and warm from above, just like from the courtyard to the hut. And until then it blows until it warms up where it was cold, and cools down where it was hot.

Why does the wind blow? (Reasoning)

They will tie a cross of two torches and tie four more torches around the cross. Everything is covered with paper. A bast tail will be tied to one end, and a long string will be tied to the other, and a kite will come out. Then they will take the kites, scatter into the wind and let them go. The wind will pick up the kite, carry it high into the sky. And the serpent trembles, and buzzes, and breaks, and turns, and waving its bast tail.

If there was no wind, it would be impossible to fly a kite

They will make four wings from the board, fix them with a cross into a shaft, and attach gears and wheels with cams to the shaft, so that when the shaft rotates, it would cling to the gears and wheels, and the wheels would turn the millstones. Then the wings will be placed against the wind: the wings will begin to turn, the gears and wheels will hook onto each other, and the millstone will turn on another millstone. And then they pour grain between two millstones; the grain is ground, and flour is poured into the ladle.

If there was no wind, it would be impossible to grind grain in windmills

When they are sailing in a boat and want to sail faster, they will take, in the middle of the boat, they will insert a large pole into the hole, a crossbar is attached to this pole. A canvas sail will be attached to this crossbar, a rope will be tied to the bottom of the sail and held in hands. Then they set the sails against the wind. And then the wind will inflate the sail so tightly that the boat bends to one side, the rope is torn from the hands, and the boat will sail with the wind so quickly that the water will growl under the nose of the boat, and the shores will definitely run back past the boat.

If there was no wind, it would not be possible to sail with a sail

Where people live, there is an evil spirit; if there were no wind, this spirit would remain so. And the wind will come, disperse the bad spirit and bring good, clean air from the forests and fields. If there was no wind, people would inhale and spoil the air. The air would all stand still, and people would have to leave the place where they breathed.

When wild animals walk through forests and fields, they always go to the wind, and they hear with their ears and smell with their noses what is ahead of them. If there was no wind, they would not know where to go.

Almost all herbs, bushes and trees are such that in order for a seed to start on a grass, bush or tree, it is necessary that dust from one flower fly to another flower. Flowers are far from each other, and they cannot send their dust from one to another.

When cucumbers grow in greenhouses where there is no wind, then people pick one flower themselves and put it on another so that the color dust gets on the fruit flower and there would be an ovary. Bees and other insects sometimes carry dust from flower to flower on their paws, but most of all this dust is carried by the wind. If there was no wind, half of the plants would be seedless.

In warm weather, steam rises above the water. This steam rises higher, and when it cools at the top, it falls down. raindrops.
Steam rises above the ground only where there is water - over streams, over swamps, over ponds and rivers, most of all over the sea. If there were no wind, the vapors would not walk, but would gather into clouds above the water and fall again where they rose. Over the stream, over the swamp, over the river, over the sea there would be rain, but on the ground, in the fields and forests there would be no rain. The wind blows the clouds and waters the earth. If there were no wind, then where there is water, there would be more water, and the whole earth would dry up.

Logical problem about the wind by Leo Tolstoy

Why, when it is windy without frost, do you feel more chilly than when it is frosty without wind?

Discuss with your child on this topic after you have conducted experiments with cold and warm air, showing the child how wind is formed. And here is the answer to this question given to children in the 19th century by Lev Nikolayevich:

Because the heat from the body passes into the air, and if it is quiet, then the air around the body heats up and stays warm. But when the wind blows, it carries the heated air and brings in cold air. Again, heat leaves the body and heats the air around it, and again the wind carries the warm air. When a lot of heat leaves the body, then you will feel cold.

Knowing the answer to the first question, try with your child to answer the following question of Leo Tolstoy to children: "Why, when tea is hot in a cup, do they blow on it?" The child can guess the correct answer by analogy with the previous logical task.

You can read the continuation of games and activities about wind and air with children in the section :

Close your eyes. It's simple. Just close your eyes.
What a stupid I am, but how will you read?
Let's agree so that you will read to someone, and this someone will close their eyes.
And then you close your eyes, and someone will tell you about that wonderful place where the ancient mountains give serenity, and the ever-young wind drives the wave first over the sea, and then over the mountains, blowing their grassy hair.

So, are your eyes closed? Dark enough?
Okay, look closely, it's the sky. You see, the bright stars are scattered like pearls that the moon dropped while running away.
Don't look for the horizon, it doesn't exist. The sky doesn't end, it just becomes the sea.
The sea is the same sky, but without stars. The black bottomless abyss quietly whispers indistinguishable words. It is said that those who were able to disassemble them went to sea, turning into dolphins. Because it is not given to people to understand the meaning of the music of the sea, and those who nevertheless understand have nothing to do among people.

You see, on the right - a dark yellow hulk - this is an old volcano. Once he was hot and threw red-hot blocks into the sea. But the sea turned out to be stronger, and now only the dreams of the old giant remind of a stormy youth, lightning and large drops of rain excite the million-year slumber of the gently sloping neighboring mountains.

And only the wind is timeless. He saw the volcano when he was young. The wind changed its shape, carving wrinkles into the hard rocks. He carried the seeds of steppe flowers along the smoothed slopes of the ancient mountains. He saw the sea, which was still a fresh lake. And when, filled with salt water, it became a real sea, it raised huge waves that sank ships.

The wind will always exist as long as the Earth exists, only the stars will survive it. The wind has always been there. He did not calm down for a minute. Because this is where he belongs. A place where the wind always blows.

You see, on the left, over the cape, the sky begins to turn red. It's the rising sun. The darkness recedes and the sky changes color. The sea turns from black to blue, the mountains turn bright yellow, and the peaks of the volcano turn green.

You see? Now open your eyes and listen further.

One day, in the light of day, a man came there with a voluminous bag on his back. He climbed to the top of a table-like mountain, and the wind immediately hit him backhand - How dare he, a mortal, invade the domain of the wind?
But the man just smiled. He was dry but strong. Gray hair covered his head, but a cheerful spark lived in his eyes. During his life he received many blows, but they all only hardened him.

The man stood leaning forward, resisting the furious pressure of the wind. Squinting his eyes, he looked at the valley, the mountains, the bay and the rocks.
- My journey is over. - thought the man - I can not find a place better than this. Places where the sun's rays warm the hilly mountains and warm air currents rush from the earth into the sky.
He took off the bag and untied it. Then he took a tightly bound piece of cloth from the bag and began to unfold it. The wind calmed down a little, it seemed to be examining the stranger and his belongings with interest.
Unrolling a huge piece of cloth, the man threw the straps over his shoulders and belt and stepped into the wind, holding the slings sewn to the fabric with his hands. And suddenly a long banner, filled with wind, rose, turning into one large wing. The man took a step, then another, and... got off the ground.

The wind, recovering from such impudence, rushed at the man in a squall to break his wing, throw him where he was supposed to be, on the ground. But the man, deftly parrying the gust, leveled the wing and whispered something to the wind.
Never before had the wind heard such words. Amazed, he fell silent, then carefully picked up the wing and carried it up to the sun.

They flew together, man and wind. A man said something to the wind, and the wind answered him. And the mountains, the sea, and the volcano below listened to the conversation.

Since then, every year, at the time when the sun painted the mountains yellow, a man appeared on top of a table-like mountain with a bag over his shoulders. And the wind met an old friend.

I don’t know if that person eventually became a bird, because I don’t know if the one who understood the music of the wind will be able to find his place among people.

I have always been interested in various natural elements. One of the most interesting and amazing natural phenomena for me is the wind. How good is a light refreshing breeze on a hot summer day, but how it spoils the weather on a dank and rainy autumn. :(

What is wind

Wind is the movement of air masses in a horizontal direction..

But for me, the wind is a stream of air that refreshes the body in the summer heat, it is a feeling of a light caressing touch of the sea breeze, it is hair fluttering through the air, the rustle of leaves on trees.

Where does the wind come from

In the past, people thought that the winds were powerful beings that had great power. According to beliefs, the winds blew for a reason. The reason for strong winds, hurricanes, storms was considered the anger of these creatures.

Now, our thinking has changed somewhat. Most of us no longer believe in the existence of spirits. Therefore, I will explain from a scientific point of view how wind is formed. This phenomenon occurs due to the difference in atmospheric pressure. Areas with different pressures have different temperatures and densities. Cold air is dense, it weighs more than warm air and the pressure in it is higher, so it tends to move into an area with warm rarefied air. As a result of these processes, wind arises.

For me, the wind is a unique phenomenon. There are many interesting facts about him. Here are just a few of them:

• The wind can blow in a vertical direction, but at the same time significantly loses in speed.
• The most terrible winds blow in Antarctica. Their power lies in their tremendous speed (just imagine, it reaches about 60 km per hour!), Combined with exceptionally low temperatures. In such conditions, I would definitely not be able to live.
• The wind with the highest speed is a tornado. This natural phenomenon usually lasts only a few minutes and, for inexplicable reasons, always occurs in the afternoon. What is surprising is that every tornado is unique. It has its own exclusive look, shade, sound and even smell!
• The highest wind speed fixed on the planet Neptune.

Friends, you often ask, so we remind you! 😉

Flights- you can compare prices from all airlines and agencies!

Hotels- do not forget to check prices from booking sites! Don't overpay. This is !

Rent a Car- also aggregation of prices from all distributors, all in one place, let's go!

How many associations evokes in me such an element as the wind. This is freedom of action, and an endless feeling that you do not need to do anything, and power, since this element can be destructive, and much more. As for me, every person can associate himself with the wind, since every person loves freedom, and this element has no boundaries, no obligations, and it cannot be tamed.

Why does the wind blow on the planet?

Wind is the movement of air. The Sun makes it move, not directly, but indirectly. The sun's rays heat the Earth, and the resulting heat heats the air, which causes it to rise. At the top it cools down and sinks back down. Also, another reason for the movement of air is the rotation of the Earth around its axis. Due to this feature of our planet, winds are formed in the Northern Hemisphere that move to the right, and in the Southern Hemisphere - to the left.

You can check how heat affects the air without leaving your apartment. To do this, you need to go to the door where the balcony is located, and take 2 candles, or napkins or fleece with you. Put these items at the bottom and top of the opening and see where they deviate. If you take candles, then you need to light them and also put them on. You can already check by the fire, where it leans, the wind will blow there. At the top of the opening, the air will be warm and will go outside, and at the bottom there will be cold air that will move in.

Wind is an element whose appearance can be predicted, but sometimes it is unpredictable. It is one of the factors that determine the weather for the near future.

Here are some interesting wind related facts:

1. Port Martin is considered the windiest place on Earth. There, the average wind speed is 20 meters per second.
2. The fastest winds in the solar system blow on Neptune. Their speed can exceed 2000 km/h.
3. In nature, vertical winds occur. This is not a long-term phenomenon, as they quickly lose their speed.
4. In 1999, the fastest wind in the state of Oklahoma was recorded, which reached a speed of 512 km per hour.

One of the first things I learned as a child was exactly why the wind blows. I asked this question to my mother when we were walking down the street, and the elements were almost raging around. When I got older, I myself learned in detail about this phenomenon.

Cause the wind blows

Before you begin to talk about why the wind blows, you need to understand what this phenomenon is. In essence, wind is a flow of horizontally moving air. It's that simple.

The occurrence of wind is due to the fact that atmospheric pressure is unevenly distributed over the surface of the Earth. This difference, in turn, is largely due to differences in air temperature in different areas.

The wind blows from an area where the pressure is high towards where the pressure is low. To better understand this principle, you can imagine an ordinary balloon. When it is inflated, the compressive forces of the rubber walls act on it. Therefore, if the ball is untied, almost all the air will quickly leave it, creating a short-term weak gust.

For reference, here are some examples of types of winds:

• trade winds and monsoons - tropical;
• westerly winds (temperate zone);
• east winds (polar belt).

Detailed information on this topic can be easily found on your own.

Why do hurricanes occur

In everyday life, any strong wind is called a hurricane. But a real such phenomenon may originate in the Atlantic or in the eastern part of the Pacific Ocean. A hurricane is a cyclone that forms in the tropical zone.

This phenomenon occurs when a certain area of ​​the ocean warms up to 26 degrees or more. This causes very warm and humid air to rise up where it condenses, causing other air masses to rise. In the process, it all twists with great force, which causes a strong wind. At the same time, it is customary to consider phenomena when air moves at a speed of 130 or more kilometers per hour as hurricanes.

Both normal and hurricane winds are of the same nature. But the latter bring great destruction with them.

One day I became interested in how to explain such a phenomenon as "gusts of wind." Having searched a little on the Internet, I came across a lot of information about Ancient Greece, where everything happened "thanks to the power of the Gods and their desires." However, modern scholars have provided many more answers than the mythology of the Greeks.

What moves the air

If we discard the many descendants and minor demigods, then we can note only a few main characters of mythology. In ancient Greece, there were 4 main gods of the winds:

• Boreas - North wind.
• Notus - South wind.
• Evus - East wind.
• Zephyr - West wind.

Mythology is silent about Notus and Evus, while whole tales and twisted myths were composed about Boreas and Zephyr, which told about their exploits, love affairs, battles, greatness and strength. With their power, they described storms, gusts of wind, bad weather.

Boreas was most revered, for which there were several reasons:

• The north wind destroyed the fleet of the Persians who attacked Greece.
• Boreas' wife was Orithyia.
• He had the ability to crush enemies with the power of the wind.

For his power in Athens, sanctuaries were erected in his honor, he helped the Greeks in the coming battles and the fruitfulness of mares. Entire epics were composed about the strength of the wings of Boreas, which told how he swept away the regiments of enemies with just one wave.

The Greeks associated gusts of wind with the wrath of the gods if it caused devastating damage to merchant ships or buildings. In such cases, they made sacrifices to the gods in order to appease them, and hoped that the bad weather would stop.

How the wind blows - modern version

After reading scientific articles, I was able to find an explanation in a more or less understandable language. The sun's rays pass through our atmosphere, while warming up all its "layers". And, as you know, with an increase in temperature, the air lends itself to expansion, but since the light passes unevenly, all areas acquire a different temperature, respectively, a different pressure. The places where the pressure starts to drop can be said to "push out" the less dense areas, which allows the air to pick up speed.

Something like this comes out that very pleasant summer breeze that pleases us on hot days. Of course, he is not particularly happy at -20 in winter, when the nose is already at the limit of freezing ...

For as long as I can remember, I have always disliked the wind. I do not surf, I do not plan to travel on sailing ships. Personally, the wind can be useful to me only in the heat, when it brings a little relief and a breath of air. But more often than not, the wind spoils my mood and hair, stubbornly drives cold rain under the umbrella, or even turns the umbrella inside out, and most importantly, makes me resentful and exclamations “yes where does it even come from, this wind? Since I walk to work every day, the last question arises more and more often, so I had to fish out my knowledge from geography lessons from the depths of my memory.

What is wind and why does it appear

Wind - it's fast,impetuous(That's right, in gusts, we feel the wind on ourselves) air movement. Air moves from a place where there is more of it to where it is less. In cold areas, there is more air per unit area. Warm air has less density and therefore does not have much pressure.

Example: why the wind almost always blows near reservoirs

I remember from childhood that our parents never allowed us to go swimming on the very first hot June day. They said, "The water hasn't warmed up yet." Really, water heats up slower than air. This means that between water and air, until the hot weather lasts for several days, there is just the same favorable space, where the wind can roam - from the colder surface of the water ( high pressure areas) to warm land ( low pressure areas).

There are regular winds (depending on the latitude, they are western or eastern), and there are those that are formed taking into account local features. The wind could be even stronger (I'm afraid to imagine it) if it moved freely. But there are obstacles on the surface of the Earth that prevent the rapid flight of air:

• the mountains;
• hills;
• forests;
• erected by man buildings.

Therefore, in the city between the houses you can hide from the wind, but in the field there is nowhere to hide. The wind is able to demolish trees and roofs of buildings on its way, and even a person is defenseless in front of it.

The only thing I appreciate about the wind is that it is a renewable energy resource, which, moreover, mankind has already learned to use.

Traditionally, in the summer, my family and I go to the lakes of Khakassia to relax from the noisy city. Tents, fire, ear, mountains, sunset and ... wind. Here is such peculiarity in the form of wind it is inherent in Khakassia, the wind is almost constant there, although I see a very big plus in this - the absence of blood-sucking insects. But why the wind blows, it is worth understanding.

What is the wind

The wind itself is a movingairflow. Winds differ in strength, direction and duration. Wind is a unique phenomenon. There is a holiday in his honor - wind day and celebrate it on June 15th. The purpose of creating such a holiday is to attract attention society to wind energy potential. Indeed, according to experts in this field, wind energy helps to solve problems not only of the energy plan, but also economic and environmental.

Why is it windy

More Halley explained occurrence of wind By the way, that was over 300 years ago. The thought of his conjecture was as follows: comes into action when the temperature drops archimedean force,warm air rises and cold air sinks.

The scientific point of view confirms Halley's thoughts, modern scientists formulate the cause of the wind as follows: uneven heating of the earth's surface.

The most curious thing about the wind

You can observe the wind in absolutely different parts of the Earth. I will reveal the most inquisitive facts about the wind.

In addition to many scientific varieties of wind, there is also a classification given by mankind.

• Wind is a doctor. So people call the cool, summer sea breeze.

• watermelon wind. It is present on the Turkish coast of the Aegean Sea, during the ripening of melons.
• Baby wind. A mild Kamchatka wind helps women dry clothes quickly.

Why does the wind arise in the mountains

So it came to explain the cause of the occurrence of wind in the highlands of the Republic of Khakassia. Mountains can act as wind-forming factor, so be it barrier for him. At high altitudes in the mountains, the air warms up faster than in the lowlands; low pressure zone, which leads to wind formation. Here is such an interesting phenomenon is the wind. And I will tell my children about it by the fire on my next trip to the lakes.

How to explain to a child why the wind blows

I will say from personal experience that for children at an early age, this phenomenon is often of particular interest. The child cannot understand why the wind blows in one place and not in another. The main thing is to say that cold wind is formed due to low air temperature.

For my daughter to understand everything, I showed her a good example. She took an incompletely inflated balloon and began to blow it with a hair dryer. ball noticeably increased its volume and climbed up. So I made it clear warm air light, he always rises. After that, I took the same balloon and put it in the refrigerator. She began to tell her daughter that the Earth is huge, so in one place can be cold, and on the opposite side will be hot at the same time. I took the ball out of the fridge and we saw that it was several times reduced its volume.

Through this experiment, my child realized that cold air always tends to occupy the territory of warm air. 0

Dominance of the wind on the planet

In most places Earth dominated by air masses and have a certain direction. Usually, at the poles East winds meet moderate climate - western, and in tropical the wind is blowing east again. Places of calm, where the winds almost do not prevail, are found in polar region and subtropical zone. Here the air moves, mainly, vertically which is the reason for the high humidity levels.

The role of wind in people's lives

In people's lives, the wind plays a huge role, influencing:

1. transport design;
2. energy extraction;
3. recreation and sports;
4. increase in destruction.

The first point is the use of the wind for movement on ships with sails or on non-powered aircraft (for example, a hang glider). as a source energy wind was used for the first time Sinhalese() to kindle the stove. Another example is the use of windmills for both mechanical processing and energy production. The first mention of the mill is attributed Heron who lived in 1st century AD. Currently gaining momentum wind energy(wind power plants).

wind farms

In sports and recreation used for hang gliding, paragliding, hot air ballooning, etc. If speak about destructive the action of the wind, it can both destroy a poorly built bridge with sharp gusts and damage power lines. Also, the wind can exacerbate the spread of a fire. Wind speed from 12 m/s capable of knocking down a large tree. Winds with speed 35 m/s capable of damaging buildings, stripping paint off cars, or breaking windows. And, here, before the wind with speed 90 m/s not a single building in the world is able to resist.

Really, which way does the wind blow? Will you answer this question? Today - one way, tomorrow - the other! And meanwhile it is possible to answer, and even not so difficult. For starters, it’s enough ... to flood the stove! As soon as the fire flares up, bring the feather clamped in your fingers to the firebox and release it. Feather as if by itself will fly into the fire! What took him there?

Warm air is lighter than cold air and therefore always tends to rise. Having warmed up in the stove, he, along with the smoke, flies into the chimney. And in place of the warm air that has flown away from the room, cold air rushes into the stove. He took the feather.

The same thing happens in nature. The only stove there is the sun, which sends its hot rays to the earth. The heat from the heated soil is transferred to the air. Entire rivers of air float from the earth straight up. But the earth heats up unevenly. It is more difficult to warm up a forest or water than, say, a field. And now, in place of the warm air rising from the field, colder air rushes from the forest. That's why on a hot summer day, coolness blows from the forest!

Well, why does the wind still blow? Because warm air weighs less than cold air. It is less pressing on the ground. And in places in the neighborhood, where it is colder, the pressure is stronger, it forces the cold air to take the vacant place. The place where the weight of the air cargo has decreased is called an area of ​​low pressure. Winds blow from all sides. But not directly to the center, but obliquely, because our planet rotates, and rotation deflects the direction of the wind. As a result, around the area of ​​low pressure, a kind of ring of winds is obtained. It reaches hundreds and even thousands of kilometers across. This phenomenon is called a cyclone. The cyclone moves, making 30 or more kilometers a day. At its border, the sky is covered with clouds, it is raining, and in the middle it is warm.

But, having risen to a great height, the masses of warm air, of course, do not remain in the same place. They fly quickly to where the cold, heavier air has settled. Moving at high altitude, the streams of warm air cool down and become heavier. Arriving at the vacant place, they also begin to descend ... This is how a high pressure area arises. The accumulated masses of cold air press harder on the surface of the earth than in surrounding places. Of course, the winds come up again. They should blow in all directions from the middle of the high pressure area, but, as we have already said, the rotation of the earth deflects their direction, and again it turns out like a ring of winds. This is an anticyclone.

Different winds rush over our planet. The paths of some are so bizarre that even meteorologists cannot always calculate them in advance, while the paths of other winds are constant, like a clock pendulum. For example, the pendulum wind is a breeze. It blows only on the coast. Why? The sun rose and began to warm the earth and the sea. The earth's surface heats up faster than the sea, the waves continuously mix the upper - warm, and lower - cold water. Therefore, during the day, the air over hot land is warmer than over the sea. It rises, and in its place a light breeze begins to blow from the sea to the land - a sea breeze. At night, everything happens the other way around. The earth is cooling faster than water, and now the wind blows from land to sea; it's a coastal breeze.

There are other pendulum winds, for example, monsoons. Their permanent address is the tropical zone, which extends on both sides of the equator. They blow especially diligently in the countries lying on the shores of the Indian Ocean. Monsoons are seasonal winds. Of course, you remember that at the time when we have winter, it is summer under the tropics. Here the monsoons blow where it is warmer, where the air pressure is less.

In summer, monsoons blow from the ocean to land, and in winter from land to the ocean.

In the tropical zones of the oceans, another "disciplined" winds blow non-stop - the trade winds. At the equator, the boundless water surface of the ocean, like a giant central heating battery, warms and warms the air. Light, warm, it continuously flows upward, and colder air flows in its place from the north and south. This is the trade winds. The rotation of the earth deflects them to the west. Using this feature of stable and reliable trade winds, sailors made many geographical discoveries. The trade winds inflated the sails of Columbus, Magellan and other brave sailors. The Spaniards called them "winds of crossings", the British dubbed them "trade winds".

The wind does a lot of good things. It turns the silver wheels of wind turbines, it pollinates the flowers of many plants, the wind carries the seeds. But most importantly, he is the master of the weather.

The wind brings with it clouds, rain, snow...

The laws of movement of air masses are studied by meteorologists. All winds are strictly registered.

Hundreds of weather stations are scattered all over the earth. Our meteorologists hunt for the weather in sultry deserts, go against storms on ships without seeing the sun for months, live at the drifting stations "North Pole", they are not stopped by eighty-degree frosts and gale-force winds of Antarctica.

Day and night, scientists monitor the life of the air, measure its temperature, humidity, determine the strength and speed of the wind. In the most different parts of our country, weather scouts rise up every now and then. These are rubber balloons inflated with hydrogen. The passengers of these balloons are small automatic devices. With the help of a radio transmitter, they tell about everything that is happening in the air ocean. Above the balloons, special meteorological rockets are launched, thousands of radio signals - reports - are rushing into the air day and night.

In Moscow, at the Central Institute of Forecasts, information received from all weather stations in the world is put on maps with hundreds of thousands of numbers and icons. Looking at such a map, a scientist will not only tell what the weather is like in Kazakhstan or Brazil today, but he will be able to roughly determine what it will be like tomorrow, in a week. But, in order to say not approximately, but exactly, you need to calculate where and at what speed the winds blow, how they will behave along the way, where they will meet, where they will heat up, where they will cool, where they will turn ... To calculate this, a person needs months. But now there are calculating machines; they make all the calculations in a few minutes, and we will find out what the weather will be like tomorrow in Moscow, Kyiv or Cuba. The machine will say everything.

The more information about the weather is collected from all corners of the earth, the more accurate the forecasts will be, the further scientists will be able to look ahead.
