There are steady winds that always blow in the same direction because of the pattern of how air moves through the atmosphere over the entire planet. … These winds turn to the right in the Northern Hemisphere and to the left in the Southern Hemisphere because of Earth’s spin, a phenomenon known as the Coriolis Effect.

What would happen if the wind stops blowing?

Absent a gentle breeze or mighty gale to circulate both warm and cold weather around the Earth, the planet would become a land of extremes. Areas around the Equator would become intensely hot and the poles would freeze solid. Whole ecosystems would change, and some would completely disappear.

Why is wind so strong?

A pressure gradient is how fast atmospheric pressure changes over distance. So, when pressure changes rapidly over a small distance, the pressure gradient force is large. Strong winds almost always result from large pressure gradients.
