Hadley cell is the model of the Earth’s atmospheric circulation proposed by George Hadley in 1735. In this model, air rises up into the atmosphere at or near the equator, flows toward the poles above the surface of the Earth, returns to the Earth’s surface in the subtropics, and flows back towards the equator. This flow of air occurs because the Sun heats air at the Earth’s surface near the equator. The warm air rises, creating a band of low pressure at the equator.
Explain how the Hadley cells function, and what winds they generate.
