"Wind, wind, you are powerful ...""Every fifth-grader knows by heart: what is your power, where does it come from, how are you born, the wind is a breeze-wind? Time that is as elusive as you, runs and succeeds a century after a century, and people all ask the same question: "What is the wind, where does it come from?" Others answer something, each in his own way. "The wind is born from trees," says someone, "trees are rocking and chasing the air." This version very cute, but someone is shaking the trees? "How? - the hero of the story of V. Veresaev answers. - God!"

If this idle curiosity - it sounded andforgotten. Breeze blows in the street a wind-breeze - means, so it is necessary. But what determines your strength and speed, the wind, why are you light and playful, angry and cruel? This is already a serious question, it's not for nothing that the best scientific minds continuously study what the wind is, and on what factors its intensity and direction depend. Thanks to their discoveries, a person today can predict, in what direction, with what force you blow. But you do not let yourself be seduced: is not the effect of surprise - your favorite game?

Why is it always windy in the mountains and on the coast?Because in places of contrasting atmospheric pressure the circulation of warm and cold air flows is continuous, only its intensity changes. This is especially noticeable on the seashore, where you, the wind, are sporting day and night. And all because the sun heats the land faster, while the thickness of the water warms up slowly. A warm wind flows upward over the earth, giving way to a cold air stream from the side of the water. And the wind begins to blow. That's what the wind from the sea, which blows constantly. Although no, at night, the reverse movement begins: the earth cools faster, and the sea still keeps heat, and now the wind changes direction - from shore to sea.

You rejoice, the wind, because our knowledgetoo narrow. There are other hypotheses about what a wind is. There is a so-called Coriolis force, which also characterizes the movement of air currents during the rotation of the Earth. According to the French scientist Gaspar-Gustav Coriolis, our planet rotates at a greater speed than its atmospheric layer, and the air masses deflect, creating flows. And there are still eternal, or prevailing winds, blowing along the equator and from the poles of the Earth.
They say that a person knows three percent of what is.Does he know? What do you think, wind-wind-wind? Or do not we need to know anything, it's better to dwell on simple knowledge: the wind happens, because the trees are rocking, and God is shaking them ...
