Hadley, n. Meteorol.|ˈhædlɪ|
The name of George Hadley (1685–1768), English lawyer and scientific writer, used, usu. attrib., with reference to a model of air flow in the Earth's atmosphere devised by him in 1735 (Phil. Trans. R. Soc. XXXIX. 58) to explain the trade winds, as Hadley circulation, Hadley theory; Hadley's law, Hadley's principle; Hadley cell, an atmospheric convection cell on a global scale; spec. each of two such cells between the equator and latitudes 30°N and S, in which equatorial air rises, moves polewards and eastwards, sinks, and moves equatorwards and westwards again.

Kuiper Atmospheres of Earth & Planets ii. 19 Wind and temperature data..in the Marianas and in the Marshalls..show that in these regions also the trade winds are far deeper than might be expected on the basis of the Hadley theory. 1955Sci.
