convective cell The pattern formed in a fluid when local warming causes part of the fluid to rise, and local cooling causes it to sink again elsewhere. The atmosphere in low latitudes forms such cells, known as Hadley cells, as warm equatorial air rises, moves away from the equator and cools, and then descends over the subtropics.
