Where are the global winds?

Global Winds

Trade winds – Trade winds occur near the equator and flow from either the north or south towards the equator. They curve towards the west due to the spin of the Earth. Prevailing westerlies – In the middle latitudes of the Earth between 35 and 65 degrees latitude are the prevailing westerly winds.

Why do jet streams flow from west to east?

Why the wind moves from west to east.

However air moving toward the poles retains its eastward momentum while the earth’s rotational velocity decreases beneath it. The result is the wind moves faster than the earth rotates so it moves from west to east (relative to us at the surface). The Coriolis effect.

How easterly jet streams are formed?
