For Hadley Cell we have terms and definitions in 4 topics. The topics are Climate, Climatology, Physical Geography and Science.

Hadley Cell (Climate)

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 degrees). 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.

Hadley Cell (Climatology)

A thermal circulation consisting of rising air near the equator and sinking air near 30 degrees latitude

Hadley Cell (Physical Geography)

Three-dimensional atmospheric circulation cell located at roughly 0 to 30° 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° North and South.

Hadley Cell (Science)

Vertically-oriented circulating air patterns present in the tropical atmosphere. See Figure VII-9 on page 229.
