What is the location of westerlies?
The westerlies, anti-trades, or prevailing westerlies, are prevailing winds from the west toward the east in the middle latitudes between 30 and 60 degrees latitude. They originate from the high-pressure areas in the horse latitudes and trend towards the poles and steer extratropical cyclones in this general manner.
What do the polar easterlies do to weather?
atmospheric circulation In the northern polar regions, where water and land are interspersed, the polar easterlies give way in summer to variable winds.
Where is the trade winds located?
The trade winds can be found about 30 degrees north and south of the equator. Right at the equator there is almost no wind at all—an area sometimes called the doldrums.
What is an example of polar easterlies?
Fairbanks, to use your example, is far enough North that the prevailing winds are polar easterlies. The southern polar easterlies are mostly over Antarctica. Such ” polar easterlies ” are a common feature of the system of winds that blow over high latitudes.
Why do polar easterlies occur?
Cold air subsides at the pole creating the high pressure, forcing a southerly (northward in the southern hemisphere) outflow of air towards the equator. Since the winds originate in the east, they are then known as easterlies.
Why is polar wind cold?
In the polar regions, because of the low temperatures, evaporation and water-vapour content in the atmosphere are very low in winter. The water-vapour capacity of the atmosphere increases with every degree Celsius of air temperature.
Why is it called trade winds?
The trade winds were named by the crews of sailing ships that depended on the winds during westward ocean crossings. …
What degree are the polar easterlies?
Polar Easterlies Approximately 60 degrees north and south latitude warm air is rising creating low pressure areas. Winds form as they more from high pressure areas near the poles toward the low pressure areas 30 degrees below each of the poles.
