A direct thermally-driven and zonally symmetric large-scale atmospheric circulation first proposed by George Hadley in 1735 as an explanation for the trade winds It carries momentum, sensible heat, and potential heat from the tropics to the mid-latitudes (30° ) The poleward transport aloft is complemented by subsidence in the subtropical high pressure ridge and a surface return flow The variability of this cell and the Walker cell is hypothesized to be a major factor in short-term climatic change (Source: Carbon Dioxide Information Analysis Center, 1990)
A thermally driven, global band of rotating air approximately 30° latitude in width, in both the northern and southern hemispheres, that drives weather systems and controls climate
Three-dimensional atmospheric circulation cell located at roughly 0 to 30 degrees north and south of the equator The Hadley cell consists of rising air (intertropical convergence zone) at the equator and descending air (subtropical highs) at 30 degrees north and south
A direct thermally driven and zonally symmetric circulation under the strong influence of the earth's rotation, first proposed by George Hadley in1735 as an explanation for the trade winds It consists of the equatorward movement of the trade winds between about latitude 30 and the equator in each hemisphere, with rising wind components near the equator, poleward flow aloft, and, finally, descending components at about latitude 30 again In a dishpan experiment, a Hadley cell is any direct thermally driven vertical cell of the approximate scale of the dishpan
a large circulation pattern in the lower atmosphere distinguished by rising air in the equatorial regions and descending air in the subtropics Horizontal flow at the surface and aloft closes the circulation pattern
A part of the atmospheric circulation system extending from the Equator to 30° latitude on both sides of the Equator It is a thermally-driven system in which heated air rises at the Equator, flows poleward, cools and descends at subtropical latitudes, and then flows back towards the Equator This description was suggested by Hadley in the 18th century
