Polar Easterlies: From 60-90 degrees latitude.
Prevailing Westerlies: From 30-60 degrees latitude (aka Westerlies).
Tropical Easterlies: From 0-30 degrees latitude (aka Trade Winds).
POLAR EASTERLIES - Winds with an easterly component at the surface near the Earth's poles, usually at latitudes more than 60 degrees. In the north polar regions, these winds are from the northeast.
The Polar Easterlies result from the outflow of the Polar high, a permanent body of descending cold air which makes up the poleward end of the Polar circulation cell. These winds, though persistent, are not deep.
easterlies: winds that come from the East. Examples are equatorial easterlies, tropical easterlies (trade winds), and polar easterlies.
eclipse: when one celestial body, such as the sun or the moon, hides another from view.
Polar Easterlies: Located at 60 - 90 degs. North Latitude.
Polar Front: Located along the northerly jet stream.
Polar front Transition zone between cold polar easterlies and mild midlatitude westerlies.
easterlies - Any winds with components from the east, usually applied to broad currents or patterns of persistent easterly winds, the "easterly belts," such as the equatorial easterlies, the tropical easterlies, and the polar easterlies.
