he region of the Earth receiving the Sun's direct rays is the equator. At this line of latitude, the air is heated and rises, leaving low-pressure areas behind. Moving to about thirty degrees north and south of the equator, the warm air from the equator begins to cool and sink. Between thirty degrees latitude and the equator, most of the cooling, sinking air moves back to the equator. The rest of the air flows toward the poles. Every latitude has a general wind pattern, which is named for the generation of the wind. The air movements toward the equator are called trade winds, which are characterized by warm, steady breezes that blow almost continuously. The trade winds coming from the south and the north meet near the equator. These converging trade winds produce general upward winds as they are heated, so there are no steady surface winds. This area of calm is called the doldrums.

Between thirty and sixty degrees latitude, the winds that move toward the poles are called the prevailing westerlies.Prevailing westerlies in the Northern Hemisphere are responsible for many weather movements across the United States and Canada.

At about sixty degrees latitude in both hemispheres, the prevailing westerlies join with polar easterlies to reduce upward motion. The polar easterlies form when the atmosphere over the poles cools.
