Does the earths rotation cause wind on earth?

Question

What really cause the winds on earth, this is question my soldiers and I talk about here in Iraq?

Answer 1

Think of it this way:

If the rotation of the earth DID cause wind, then wind woul always flow one direction, since the Earth rotates east, then wind would always be from east to west (wind lagging behin Earth). On top of that, the equator would have the highest wind speeds, because it's where the Earth is spinning the fastest.

In reality, the equator has hardly any wind, and wind not only flows from east to west, but from west to east, and sometimes even north/south directions!

WInd is caused by air moving from high pressure, to areas of low pressure. Like farting. High pressure in your colon, then the fart escapes to the outside, where there's less pressure.

Wind is msotly causes by atmospheric pressure.

Simply put: heat makes air rise, causing an area of low pressure, like, a fan pushing air out of the way, or the way steam rises. Then, this area is imediately filled with more air, and this movement is interprested as wind.

On a global scale, the hot winds over the equator rises, and has less pressure (less dense), versus the cold winds in the artic have low pressure. Ie: winds are always escaping from cold places to hot places, and the winds that were in a hot place get shoved to a cold place, then it cycles, causing wind.

It also happens on local scale, like air moving from the cold mountain peak, down to the surrounding valley, then up again to the mountain. Things like lakes and oceans also have huge thermal properties, heating and cooling large amounts of air, that's why there's alot of wind at many ports, making sail boats possible.

Answer 2

Cause Of Wind

Answer 3

It's a combination of a few things.The most important of wich are convection, and the lay of the land. The rotation of the planet does have a profound effect on wind direction, but is not the root cause.
Stay safe over there guys!

Answer 4

No it doesn't. The atmosphere moves with the surface of the earth. It is held there by gravity and friction. The atmosphere is a very thin layer compared with the size of the planet. Wind is caused by pressure differences which in turn are caused by temperature differences.

Answer 5

no,its caused by heat and ocean stuff,moutains
