 Hadley cell

The Hadley cell, named after George Hadley, is a global scale tropical atmospheric circulation that features air rising near the Equator, flowing poleward at a height of 10 to 15 kilometers above the earth's surface, descending in the subtropics, and then returning equatorward near the surface.This circulation creates the trade winds, tropical rain-belts and hurricanes, subtropical deserts and the jet streams.
