2 Φεβ 2023 · Global winds are winds that develop in belts distributed all around the world. Like local winds, the leading cause of global winds is unequal heating of the atmosphere, causing a difference in air pressure.
Global Wind Explained. The illustration below portrays the global wind belts, three in each hemisphere. Note that the U.S. lies primarily in the Westerly Wind Belt with prevailing winds from the west. Each of these wind belts represents a "cell" that circulates air through the atmosphere from the surface to high altitudes and back again.
Hadley cell, model of the Earth’s atmospheric circulation that was proposed by George Hadley (1735). It consists of a single wind system in each hemisphere, with westward and equatorward flow near the surface and eastward and poleward flow at higher altitudes. The tropical regions receive more heat.
Wind is the movement of air across Earth’s surface. It is caused by differences in atmospheric pressure. The global atmospheric circulation pattern is determined by temperature differences, especially the difference between heating at the equator and the poles, and by the Earth’s rotation.

Global winds if the Earth rotated three times faster than today. Note that this uses the present-day temperature gradient and three-cell global circulation pattern, both of which may not have existed early in Earth’s history.
Wind is a renewable resource that does not directly cause pollution. Wind energy is harnessed through powerful turbines. Wind turbines have a tall tubular tower with two or three propeller-like blades rotating at the top.
