Polar easterlies

From Freepedia

The polar easterlies are the prevailing winds that blow from the high-pressure area of the polar highs towards the low-pressure area of the polar front at around 60 degrees latitude. They come about as a result of the outflow of the Polar high, with cold air descending at the pole and forced eastward by the Coriolis effect. Unlike the westerlies further south in the middle latitudes, the polar easterlies are often weak and irregular.
