Intertropical convergence zone
This graphic depicts both the northern and southern Intertropical Convergence Zones (ITCZ). The northern Intertropical Convergence Zone is created when the surface trade winds from the northeast meet the surface southeast trade winds. This converging, or mixing air is forced to rise, and spawns clouds, showers and thunderstorms.
