Document Summary
The trade winds are the prevailing pattern of easterly surface winds found in the tropics, within the lower portion of the earth"s atmosphere, in the lower section of the troposphere near the earth"s equator. Intertropical convergence zone: appears as a band of clouds consisting of showers, with occasional thunderstorms, that encircles the globe near the equator. The solid band of clouds may extend for many hundreds of miles and is sometimes broken into smaller line segments. It exists because of the convergence of the trade winds. In the northern hemisphere the northeast trade winds converge with southeast winds from the southern hemisphere. The point at which the trade winds converge forces the air up into the atmosphere, forming the itcz. Northern and southern were we have the driest places in the earth (deserts) Thermohaline circulation (global or ocean conveyor belt): winds drive ocean currents in the upper 100 meters of the ocean"s surface.
