Hadley, George -
(1685-1768): English meteorologist. He related the direction of trade winds to the rotation of the Earth in his famous paper "Concerning the Cause of the General Trade Winds," published in 1735. His name is attached to “Hadley cells,” the air circulation that attributes the trade winds as part of a cell driven by rising air in the tropics (a concept first postulated by Edmond Halley in 1686).
