Winds that blow from the east as they flow off the high Antarctic polar plateau. Polar easterlies help generate ocean surface currents (east wind drift) in the Southern Ocean.
A wind that blows from the North and South poles in an easterly direction
In the global pattern of prevailing winds, winds that blow from the polar high toward the subpolar low. These winds, however, should not be thought of as persistent winds, such as the trade winds.
Winds that originate at the polar highs and blow to the subpolar lows in a east to west direction.
The rather shallow, irregular, and diffuse easterly winds located poleward of the subpolar low pressure belt. In the mean in the Northern Hemisphere, these easterlies exist to an appreciable extent only north of the Aleutian low and the Icelandic low.
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.
