Scientists describe and name winds based on the direction from which What are prevailing winds and why are they important? Migrating extratropical cyclones and anticyclones associated with contrasting warm moist air moving poleward from the tropics and cold dry air moving equatorward from polar latitudes yield periods of rain (sometimes with violent thunderstorms), snow, sleet, or freezing rain interrupted by periods of dry, sunny, and sometimes bitterly cold conditions. Prevailing westerlies are the winds that cause major weather movements across the United States and Canada. Winds are named for the direction they come from.

When air moves in a definite direction, it is called wind. When the air reaches the western extreme of the high-pressure centre, it turns poleward and then eventually returns eastward in the middle latitudes. The Coriolis force explains why winds circulate around high and low pressure systems as opposed to blowing in the direction of the pressure gradient. Poleward of these centres, the surface winds turn westward again over significant portions of the subpolar latitudes. of the poles. The rotation of the earth means that they are the generally prevailing winds in northern latitudes. Unlike the westerlies in the middle latitudes and trade winds in tropics, the polar easterlies are often weak and irregular.
