The Hadley cell, named after George Hadley, is a tropical atmospheric circulation that is defined by the average over longitude, which features rising motion near the equator, poleward flow 10–15 kilometers above the surface, descending motion in the subtropics, and equatorward flow near the surface. This circulation is intimately related to the trade winds, tropical rainbelts & hurricanes, subtropical deserts and the jet streams.

Famous quotes containing the word cell:
“She that but little patience knew,
From childhood on, had now so much
A grey gull lost its fear and flew
Down to her cell and there alit,
And there endured her fingers touch
And from her fingers ate its bit.”
—William Butler Yeats (18651939)
