definition: The hadley cell refers to a somewhat idealized vertical circulation of air in the Earth's atmosphere and comprises the principal component of the general circulation pattern of the Earth's atmosphere. The Hadley Cells are comprised of a trough of low pressure girdling the globe in an equatorial and tropical band (the intertropical convergence zone, or ITCZ) and its associated rising air and a ridge of high pressure (the subtropical highs) where the air subsides back to the surface.
