Why do we have slow and strong winds where is that came from anyway and except the machinery what kind of a thing produce it?

Answer 1

Imagine that the Sun is shining somewhere to the east of you. The Sun produces warming and the air rises. Other air has to come from somewhere to fill back in. That is what the wind is. It's more complicated of course, Warm air rising is called a thermal-low. Usually it is cooling and sinking air that sucks air into it. Warm air expands and has to go somwhere, so it goes into a lower pressure area. So basically wind and weather are cause by uneven heating and cooling of the atmosphere. And that will always happen on a planet that rotates.

Answer 2

Slow winds typically result from differences in air pressure caused by the unequal heating of Earth's surface. Strong winds are often due to the large pressure gradient between two areas. Aside from machinery, natural phenomena such as atmospheric circulation patterns, temperature differences, and geographic features like mountains can produce wind.
