Polar easterlies
From Wikipedia, the free encyclopedia
(Redirected from Polar Easterlies)
The polar easterlies are the prevailing winds that blow from the high-pressure areas of the polar highs at the north and south poles towards the low-pressure areas of the polar fronts at around 60 degrees latitude (north and south). Cold air subsides at the pole creating the high pressure, forcing a southerly (northward in the southern hemisphere) outflow of air towards the equator; that outflow is then deflected eastward by the Coriolis effect. Unlike the westerlies in the middle latitudes, the polar easterlies are often weak and irregular.
