Why is polar wind cold?
Why is polar wind cold?
But even during the polar day, the period of continuous sunlight, only a relatively small amount of solar energy reaches the Arctic or Antarctic regions due to the low angle of incoming rays. These two phenomena thus form the basis for sustained cold conditions in the northern and southern polar regions.
Why polar easterlies are cold and dry?
Polar easterlies are cold and dry winds coming from polar highs of North and South poles towards low-pressure Westerlies at high latitudes. Cold air from the poles moves out causing a high pressure in the area and as a result, equatorward outflow of air takes place which gets deflected towards west by Coriolis effect.
What are easterlies and westerlies?
When air moves in a definite direction, it is called wind. If the winds move from west to east, they are called westerlies. If they move from east to west, they are called easterlies. The direction of wind is also affected by coriolis affect.
Is polar easterlies global or local?
Global wind patterns: Winds are named by the direction from which they blow. The globe is encircled by six major wind belts, three in each hemisphere. From pole to equator, they are the polar easterlies, the westerlies, and the trade winds.
Why are polar global winds called polar easterlies think?
Think! Polar Global winds are called Polar Easterlies because they begin in the east. At the poles, the cooler air sinks and moves back toward the equator. Global winds do not move directly from north to south or south to north because the Earth rotates.
What are the two types of local winds?
The main types of local winds are: Sea breezes and land breezes, Anabatic and katabatic winds, and Foehn winds.
What is a strong straight wind called?
A derecho (/dəˈreɪtʃoʊ/, from Spanish: derecho [deˈɾetʃo], “straight” as in direction) is a widespread, long-lived, straight-line wind storm that is associated with a fast-moving group of severe thunderstorms known as a mesoscale convective system and potentially rivaling hurricanic and tornadic forces.
