General circulation of the atmosphere- air flow system on the globe, which promotes the transfer of heat and moisture from one area to another. Air moves from high pressure areas to low pressure areas ... Areas of high and low pressure are formed as a result of uneven heating of the earth's surface. Under the influence of the Earth's rotation, air currents deviate to the right in the Northern Hemisphere, and to the left in the Southern Hemisphere.

IN equatorial latitudes due to high temperatures there is always a belt low pressure with light winds. The heated air rises upward and spreads to the north and south. When high temperatures and upward movement of air, with high humidity, large clouds are formed. There is a lot of precipitation here.

Approximately between 25 and 30 ° N. and y. sh. air sinks to the surface of the Earth, where, as a result, belts are formed high pressure... Near the Earth, this air is directed towards the equator (where the pressure is low), deviating in the Northern Hemisphere to the right, in the South - to the left. This is how trade winds... In the central part of the high-pressure belts there is a calm zone: the winds are weak. Due to the descending currents of air, drying and warming up of the air occurs. Hot and dry areas of the Earth are located in these zones.

IN moderate latitudes with centers about 60 ° N. and y. sh. pressure low... The air rises up and then rushes to the polar regions. In temperate latitudes, western air transport prevails (the deflecting force of the Earth's rotation acts).

Polar latitudes differ low temperatures air and high pressure. The air that came from the temperate latitudes descends to the Earth and is again directed to the temperate latitudes with northeastern (in the Northern Hemisphere) and southeasterly (in the Southern Hemisphere) winds. Little precipitation.

Winds

Wind - horizontal air movement relative to the earth's surface. It occurs as a result of uneven distribution atmospheric pressure and its movement is directed from areas with higher pressure to areas where pressure is lower. The cause of the wind is the difference in pressure between territories, and the reason for the difference is the heterogeneity in heating. The direction of the wind is determined by the part of the horizon from which it blows (the north wind blows from north to south). The deflection force of the Earth's rotation acts on the direction of the winds.

The winds are varied in origin, nature, meaning ... The general circulation of winds due to the difference in atmospheric pressure includes: monsoons, zonal transfers, cyclones, anticyclones... Local atmospheric circulation is expressed in breezes.

Types of winds.

TO local winds include breezes, mountain-valley, hair dryers, bora, sirocco, samum, etc. In the equatorial belt, low pressure prevails, in the subtropical belt - increased, so the winds blow towards the equator. Under the influence of the Coriolis force, they deviate in the northern hemisphere to the right and have a northeast direction, in the south - to the left and become southeast.

Fyeong - warm, dry and gusty wind from the mountains. It blows when the pressure is lower on one side of the ridge than on the other. Bora - strong, cold, gusty wind, which is formed when cold air passes through low ridges to the warm sea.

Trade winds- constant winds in the tropical regions of the Northern and Southern Hemispheres, blowing from high pressure belts (25-35 ° N and S) to the equator (into the low pressure belt). Under the influence of the Earth's rotation around its axis, the trade winds deviate from their original direction. In the Northern Hemisphere, they blow from northeast to southwest, in the Southern Hemisphere - from southeast to northwest. The trade winds are characterized by high stability of direction and speed of movement.

In the temperate latitudes of both hemispheres, western transfers dominate ( westerly winds). Westerly winds of the temperate zone - the prevailing winds blowing in temperate approximately between 35 and 65 degrees north and south latitude. These winds blow mainly from west to east, more precisely from the southwest in the Northern Hemisphere and from the northwest in the Southern Hemisphere.

During the day, land heats up faster than the sea, the air above it is warmer than above water. Above the ground, an area of \u200b\u200blow pressure is formed, above the water - an increased one, and the wind blows from the sea to the land. it day breeze... At night, the land cools faster than the sea, over which an area of \u200b\u200breduced pressure is formed, and the wind blows in back side - night breeze.

The mechanism of formation is similar monsoons - seasonal winds that change their direction twice a year: in summer they blow on land, in winter - at sea. In winter, the air is colder over land and warmer over the ocean. Consequently, the pressure is higher over the mainland, lower - over the ocean. Therefore, in winter, air moves from the mainland (areas of higher pressure) to the ocean (above which the pressure is lower). In the warm season, the opposite is true: monsoons blow from the ocean to the mainland. Therefore, in the areas of monsoon distribution, precipitation falls, as a rule, in summer. Due to the rotation of the Earth around its axis, monsoons deviate in the Northern Hemisphere to the right, and in the Southern Hemisphere to the left of their original direction.

Special wind systems.

As a result of uneven heating of the earth's surface and the deflecting force of the Earth's rotation, huge (up to several thousand kilometers in diameter) atmospheric vortices are formed: cyclones and anticyclones. Cyclone - atmospheric vortex with reduced pressure in the center. Anticyclone - atmospheric vortex with high blood pressure in the center.

Cyclone – an ascending vortex in the atmosphere with a closed area of \u200b\u200blow pressure, in which winds blow from the periphery to the center (counterclockwise in the Northern Hemisphere, clockwise in the Southern Hemisphere). The average speed of the cyclone is 35-50 km / h, and sometimes up to 100 km / h. In a cyclone, air rises upward, which affects the weather. With the appearance of a cyclone, the weather changes quite sharply: winds intensify, water vapor rapidly condenses, generating powerful clouds, precipitation falls.

Anticyclone - a descending atmospheric vortex with a closed area of \u200b\u200bincreased pressure, in which winds blow from the center to the periphery (in the Northern Hemisphere - clockwise, in the Southern Hemisphere - counterclockwise). The speed of movement of anticyclones is 30-40 km / h, but they can linger for a long time in one place, especially on the continents. In the anticyclone, the air descends, becoming drier when warmed up, since the vapors contained in it move away from saturation. This, as a rule, excludes the formation of clouds in the central part of the anticyclone. Therefore, during the anticyclone, the weather is clear, sunny, without precipitation. Frosty in winter, hot in summer.

Lesson summary " Wind. Wind systems". Next topic:

Wind... Such a familiar and commonplace phenomenon. Each person feels this element up to a hundred times a day. But does everyone understand and can explain the essence of this phenomenon?

According to generally accepted definitions, wind is the movement of air masses in a horizontal direction. Everything is simple and clear here. A more interesting question: why these very air masses move and what makes them do it, in other words,

Globally, wind formation is influenced by 3 closely related factors:

1. Temperature difference between different parts of the atmosphere and land.
2. Difference in pressure between different points of the atmosphere.
3. Coriolios Force - the force generated by the rotation of the Earth around its axis.

The second factor (the difference in pressure) is a direct consequence of the first factor - the pressure in different points of the atmosphere is not the same, because these points have different temperatures.

In warm parts of the atmosphere, air has less weight, since its molecules repel each other further and further with increasing temperature - accordingly, the pressure here is low. In cold places, the opposite processes occur - air molecules tend to get as close to each other as possible, which makes the air heavier and the pressure exerted on the atmosphere increases.

This is how the wind arises - air masses from the high pressure zone move to the low pressure zone, as if filling the voids in the atmosphere. To understand how and why this happens, imagine the following picture: some body of water is equally divided by a dam, and the water level on one side is 40 meters, and on the other - 60 m.If you open the dam locks, the water will instantly come out of the part where the water level is higher (i.e. from where the pressure is higher) to the other, and will flow until the water level in both parts is equal.

hurricane formation

As already mentioned, all 3 factors affect the formation of wind only on a global scale. So the force of Coriolios is involved in the formation of global planetary winds - monsoons and trade winds, which blow for up to 6 months. But for local (local) winds, the presence of only one generating factor is sufficient - the temperature difference (later - the pressure difference).

Winds play an exceptional role both for the entire planet and for human civilization. It was the wind that once carried the seeds of the first plants around the world. Winds formed reliefs, from some lands they made deserts, and from others - fertile "oases". It was thanks to the wind that man was able to quickly overcome long distances by sea, which contributed to the development of trade and sciences, as well as the birth of international relations... And tomorrow the huge and boundless force of the wind can become the main source of energy for a person.

Where does the wind come from: experiences, informative stories, speech exercises, cartoons for children. Leo Tolstoy's logic problems for children about the wind.

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

Where does the wind come from: experiences for toddlers

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

Take a basin of water. Make paper boats. You will see how to make boats in this video.

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

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

Arrange a boat competition. Which boat will swim faster to the other shore (for this you need to take a square-shaped basin or a baby bath). Ask the kid how to blow to make the boat sail quickly?

Try different winds - a soft and light breeze, a strong hurricane, a fierce 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 is suitable). Blow the sail. How should you blow to make the boat sail?

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

Fan (for children 4-5 years old)

Fan the strip of paper into an accordion fold. Or take a ready-made fan. Have your toddler fan out in front of his face. How does he feel? What is a fan for? (in hot weather, the fan gives us a breeze that cools and helps us). Now let the kid try fanning over the water. What happens to the water in the basin? Where did the waves come from?

The next day, ask the child a riddle. Ask why the riddle says “The wind is blowing - I’m not blowing” (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 can drown.) Invite your child to make paper boats and play sea battle. This game is played in pairs. You need to blow on your own and others' boats 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 (draw in more air, exhale it harder and harder).

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

This experience will help you figure out which is easier - warm air or cold air.

1. Let's try to find out where it is warmer in the room and where it is 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 above.

2. Then invite your child to hold their palm over the battery and under the battery. Where is it 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 battery (can be attached with construction tape or with Uni patafix). Open the window above the battery at the same time. Warm air will rise upward, and the piece of paper will begin to move and rise upward.

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

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

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 simple to make:

take a circle of tissue 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? (air blows).
• Place the snake over the candle flame. What happens to the snake? It will start to rotate. Why is it spinning? Because warm air goes up and lifts the snake.
• You can try for the children to do this experience themselves, but not with a candle! You need to hold the snake over the hot battery.

2. Go to a door (for example, leading to a glass 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 where the wind is blowing, you can put two candles - below and above and see where their flame is deflected. Or take a thin napkin or cotton wool and bring it to the door. Where will it go?

3. Why does the wind blow in different directions? It turns out that at the top, the air comes out of the room to the outside. This is warm air. He goes outside. And the cold air is heavier and it is at the bottom. He enters the room from the street. This is how the wind turns out in the room. But this is exactly how wind happens in nature.

It turns out wind is the movement of air! Warm air moves at the top and cold air at the bottom, and they tend to swap places.

4. You can sketch 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 below 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 ask him not to do this? Now he already knows what caused your request and will treat it in a completely different way!

Note: Do not overload the preschooler with knowledge about physical phenomena that are not yet available for understanding, and say that the distribution of atmospheric pressure 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.

Turntable experiments

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

How to make a turntable for playing with the wind

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

And this is a scheme for making a turntable.

Desert Wind Experience

The experience game can be played in a sandbox or by pouring sand into a basin. Level the sand surface. Then invite your child to become the wind and blow on the sand. Sand waves will begin to appear on the surface of his "sandy desert". If you continue to blow, the sand will move from one place to another and you will get hills. Let the child try to make "dunes" - sandy hills. This is how the wind helps the sand travel through the desert.

Let's speculate. 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 one can find good and bad sides. Important. so that he thinks independently, can 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 think together.

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

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

Speech exercise "What is the wind like?"

Choose as many words with your child as possible that describe what kind of wind 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 to notice interesting figurative words in stories and fairy tales.

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

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

Now let's find 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. And if the wind is strong? Wind. And if it is very strong? Storm, hurricane, storm, tornado.

How to carry out speech exercises for the selection of words?

I like to do these kinds of word-matching exercises with children in the form of a game. For example, if we play with words in winter, we help the wind to cover the ground with snowflakes. One word is one snowflake! And you need to cover a lot of the land shown in the picture! So we are choosing words for a very long time, because we cannot allow a bush or flower to freeze without snow! We found 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 speak the more common words.

If we play in the fall, then we help the wind to pick leaves or transfer seeds. You can think of any game situation. In such games, the child sees the result of his efforts and therefore seeks to find as many words as possible about the wind. I'm always surprised, but it's a fact - children remember exactly where THEIR snowflake or leaf, which they helped the wind, and what exactly the snowflake covered them, even if the game takes place in a large group of children !!!

I call this kind of work "visual result of speech." If you just select a lot of words, then the children do not understand the meaning - why it is needed, and they get bored. And when performing a game task with a result that can be seen, touched, they become interested! The rich vocabulary that children receive as a result of such exercises, oh, how necessary both in school and in life!

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

Educational stories for children about the wind by Lev Nikolaevich Tolstoy. The second Russian book to read - 1875

Why is there wind (reasoning)

Fish live in water, and people 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 air - blowing in our face; and sometimes you can hear, when we run, how the air whistles in our ears. When we open the door to the warm room, the wind always blows downward from the courtyard to the upper room, and on horseback blows from the upper room to 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 all day and night, sometimes in one direction, sometimes in the other. This happens because somewhere on the ground the air gets very hot, and in another place it will cool down - then the wind begins, and a cold spirit comes from below, and a warm one on top, just like from the courtyard to the hut. And until it blows until it gets warm where it was cold, and it cools down where it was hot.

Why does the wind blow? (Reasoning)

They will tie a cross of two torches, and another four torches will be tied around the cross. They will stick papers on everything. A bast tail will be tied to one end, and a long string will be tied to the other, and a snake will come out. Then they will take the kite, scatter into the wind and let it go. The wind will pick up the kite, carry it high into the sky. And the serpent trembles, and buzzes, and torns, and turns, and flutters its wet tail.

If there was no wind, you could not fly a kite

They will make four wings out of the wood, fix them with a cross into the shaft and attach gears and wheels with cams to the shaft, so that when the shaft turns, it would cling to the gears and wheels, and the wheels would turn the millstone. Then the wings will be placed against the wind: the wings will begin to turn, the gears and wheels will cling to each other, and the millstone will turn on another millstone. And then the grain is poured between the 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 on a boat and want to sail as soon as possible, they will take a large pole in the middle of the boat, 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 will set the sails against the wind. And then the wind will inflate the sail so hard that the boat bends to one side, the rope breaks from the hands, and the boat will float in the wind so quickly that the water gurgles under the bow of the boat, and the banks seem to run back past the boat.

If there was no wind, you couldn't sail with a sail

Where people live, there is a bad spirit; if there were no wind, this spirit would have remained. And the wind will come, drive away the bad spirit and bring good, clean air from the forests and fields. If there were no wind, people would breathe and spoil the air. The air would still stand still, and people would have to leave the place where they breathed.

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

Almost all grasses, bushes and trees are such that in order for a seed to form on a grass, bush or tree, it is necessary for dust to fly from one flower 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 themselves pick one flower and put it on another so that the color dust gets on the fruit flower and there is an ovary. Bees and other insects sometimes transfer 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 vapor rises higher, and when it cools at the top, it falls down drops of rain.
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 was no wind, the couples would not walk, but would gather in clouds over the water and fall again where they rose. It would rain over a stream, over a swamp, over a river, over the sea, but there would be no rain on the ground, in the fields and forests. The wind blows the clouds and waters the ground. If there was no wind, then where the water is, there would be more water, and the whole earth would dry up.

Logical problem about the wind by Lev Nikolaevich Tolstoy

Why, when it is windy without frost, do you chill more than in frost without wind?

Discuss this with your child after you have experimented with cold and warm air to show your child how wind is formed. And here is the answer to this question given to children in the 19th century by Lev Nikolaevich:

Because the heat from the body passes into the air, and if it is quiet, then the air around the body heats up and is warm. But when the wind blows, it carries away 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 comes out of the body, then you will chill.

Knowing the answer to the first question, try with the child to answer the following question of Lev Nikolaevich Tolstoy to children: "Why, when tea is hot in a cup, is it blown on?" 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 heading :

It happens that you look out the window, and there the trees are waving their branches. In fact, it is not the trees that wave their branches, but the wind blows with such force that the branches with leaves bend in different directions. The wind can be light and warm, or it can be strong and cold. And in many tales he even calls him mighty. Where does so much power come from? Why is the wind blowing?

Surely you have felt the wind blowing more than once. Huge currents of air move from place to place around our planet. What is air? It is a mixture of gases, the particles of which fly freely in space. There are no walls or boundaries in the air. However, somewhere it is warmer, somewhere cooler, somewhere there are more particles, somewhere less - but it strives to become the same everywhere. And this movement of air, its desire to mix - is the wind.

Go to the door (for example, leading to the glazed balcony) and try to determine where the wind is blowing at the top of the doorway (above) and near the floor (below). To do this, 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 it go? At the top, the air goes out of the room to the outside. it warm air... He is lighter and, rising, goes out into the street. Cold air is heavier and occupies the space freed from warm air. This is exactly how wind happens in nature.

During the day, the sun's rays penetrate the air shell of the Earth. Some of them reach the surface - they heat the soil, stones and rocks, the water of the seas and oceans. And they give this heat to the surrounding air, and the air envelope that envelops our planet - the atmosphere - heats up. It is because of the sun that the winds on our planet cannot subside.

But during the day, land heats up faster and stronger than the sea. The air above the ground rises, and the cold wind from the sea takes its place. At night, on the contrary, the earth cools down, but the water remains warm. Warm air above the water rises, and the breeze is already blowing from the shore, occupying it.

The same is happening on a huge scale on the surface of the entire planet. The warmest place on Earth is the equator. Therefore, in this strip, warm air constantly rises up. He is heading towards the poles, North and South. Then, at certain latitudes, it goes down and continues its movement, but in two directions - to the poles and back to the equator.

Another force acting on the air flow is the rotation of the Earth. Because of it, all winds in the Northern Hemisphere shift to the right, in the Southern Hemisphere - to the left.

If the sun, earth and oceans left the air alone, then after a while it would become the same temperature and humidity everywhere, and the winds would die down forever.

Do you know that…

The windiest place in the world - this is the port of Martin. It is located in Antarctica. The so-called wind pole is located here. There are 340 stormy days in Antarctica during the year with an average wind speed of about 20 meters per second.

Human history is closely related to the wind: it was he who set sail ships in motion, the blades of mills, which converted his energy into mechanical.

Fastest wind is born inside the funnel of a tornado. Its speed reaches 480 kilometers per hour.

The question of why we feel the wind, and why it even occurs in the atmosphere of our planet, is a childish one, but not every adult can give an exhaustive answer. For many, this natural phenomenon is fraught with a mystery, although from the point of view of physics everything is explained quite simply.

How to explain to a child why the wind is blowing?

So, the pressure of the earth's atmosphere is not uniform, in some places more, and in other places less. So, the wind is the movement of air masses from the high pressure area to the low pressure area, and the pressure itself becomes more the same. Accordingly, the strength of the wind depends on the pressure difference. If the pressure is the same on a certain, fairly large area of \u200b\u200bthe territory, the weather is calm.

If we consider the wind more globally, then the air warms up much more over land than over the sea. Thus, it rises up, while the cooler air above the sea surface moves and takes its place. In this way, the ground cools overnight. This occurs on a regional, continental and global scale.

The warmest place on our planet is the equator. Accordingly, the air in this area is warmer. In addition, when the earth rotates, air masses move along with sources of heat and cold.

If the earth did not rotate, then the North winds and the South winds would exist independently of each other. In other words, they would not overlap. But this is how all the North winds shift to the right, and the South winds, respectively, to the left, they partially mix. If I can put it that way, the winds do not go anywhere and they do not come from anywhere they are always there, as a regulator of temperature and atmospheric pressure.

Explaining this to a child, you can offer an example on his breathing. So, when we inhale, high pressure is created inside the lungs, they swell from the air, plus it heats up from the heat of our body. Then we exhale, creating the same wind - a small movement of a small volume of air. When we exhale recycled air in winter, it rises up in the form of steam, because it is warm. It's easy to see.

Also, the strength of the wind depends on the terrain. Everyone noticed that in open fields the wind is faster. Nothing bothers him and nothing detains him. In a city where there are a lot of high-rise buildings, or in forests where trees, air masses move more slowly, adjusting to the ambient temperature along the way.
