Due to Coriolis Force, the wind flowing from equator towards the North Pole and from North Pole towards the equator are deflected to their right while the winds flowing north-south and south-north in the southern hemisphere are deflected towards their left. These trade winds converge and meet, creating air uplift at the equator. 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. Polar easterlies: Air flowing west toward the equator and circles of wind. The word trade in those days referred to advance steadily and was synonymous with efficient sailing. Cold air subsides at the poles creating high pressure zones, forcing an equatorward outflow of air; that outflow is then deflected westward by the Coriolis effect. Winds near the surface of the Earth frequently circulate around cyclones and anticyclones, which are zones of low and high pressure, respectively. These winds are called Polar Westerlies, Prevailing Easterlies, and Trade Winds. The polar easterlies are an extension of the Westerlies, although they originate over land. As the polar easterlies move toward the equator, they become warmer and less dense. high pressure areas in the north and south poles. Winds are named by the direction from which they blow. Some of the descending air travels equatorially along the surface, closing the loop of the Hadley cell and creating the Trade Winds. The cold polar air mass is pushed by the easterlies and warm air is pushed by the westerlies. Prevailing westerlies are the winds that cause major weather movements across the United States and Canada. At the surface, the air flows from these subtropical high-pressure belts toward the Equator but is deflected toward the west in both hemispheres by the Coriolis Effect. Cold air subsides at the pole creating the high pressure, forcing a southerly (northward in the southern hemisphere) outflow of air towards the equator. What are easterlies and westerlies? Global winds occur in belts around the globe. Although their presence is discernible in long-term mean statistics accumulated over a hemisphere, such cells are often difficult to detect on a daily basis at any given longitude. These winds are The air lifts from here and at around 30 North and South, the air begins to descend toward the surface in subtropical high-pressure belts known as subtropical ridges.
