Near each pole is a climatological region of high pressure called a polar high. In these regions are often clear skies, cold dry descending air, light winds, and little snowfall. Between each polar high (at 90°) and the subpolar low (at 60°) is a belt of weak easterly winds, called the polar easterlies. 11.2.2.
2 Φεβ 2023 · The cold polar air moves at about 60° north and south towards the Equator and starts rising. This unique, permanent movement of winds across the surface of the Earth due to permanent air pressure zones creates a distinct pattern known as global wind patterns or global wind systems.
So, the first air current moves from 90 degrees (the North Pole and the South Pole) and heats up quickly at 60 degrees (northern and southern hemispheres) - the air expands, rises, and cycles back in a counterclockwise loop. These are the so-called Polar Easterlies.
1 Ιαν 2016 · Polar easterlies The Polar easterlies are dry, cold prevailing winds blowing from north-east to south-west direction in Northern Hemisphere and south-east to north-west in Southern Hemisphere. They blow from the polar high-pressure areas of the sub-polar lows .
19 Δεκ 2021 · Roughly at 60° north and south latitude, the subtropical westerlies collide with cold air travelling from the poles (polar easterlies). This collision results in the uplift of air and the creation of subpolar low pressure zones (and associated mid-latitude cyclones).
Finally, in the Polar cell, the winds travel from the northeast and are called the polar easterlies. The wind belts are named for the directions from which the winds come. The westerly winds, for example, blow from west to east.
21 Νοε 2023 · The three major global wind belts are polar easterlies, westerlies, and trade winds. The polar easterlies flow from the north and south poles towards 60 degrees north and south,...
