Usually applied to the broad patterns of persistent winds with an easterly component, such as the easterly trade winds.

deep easterlies - Same as equatorial easterlies.
deep trades - Same as equatorial easterlies.
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.
prevailing easterlies—The broad current or pattern of persistent easterly winds in the Tropics and in polar regions.
Tropical Wave(formerly known as inverted trough) - A trough or cyclonic curvature maximum in the trade wind easterlies.
Controlled burnoff and uncontrolled human initiated bushfires are widespread in the north during this season, particularly in later months, fuelled by the abundant wet season growth that has been dried by the prevailing southeasterlies.
easterly wave"A migratory wavelike disturbance of the tropical easterlies. It is a wave within the broad easterly current and moves from east to west, generally more slowly than the current in which it is embedded.
Polar Northeasterlies at 60 Degs. to 90 Degs. N. Lat. Polar Southeastlies at 60 Degs.- 90 Degs S. Lat.
Polar Easterlies: Located at 60 - 90 degs. North Latitude.
Polar Front: Located along the northerly jet stream.
A trough or cyclonic curvature maximum in the trade wind easterlies and it is not classified as a tropical cyclone. The wave may reach maximum amplitude in the lower middle troposphere.
Tropical Weather Discussion ...
TROPICAL WAVE Another name for an easterly wave, it is an area of relatively low pressure moving westward through the trade wind easterlies.
EASTERLY WAVE- An inverted trough in the tropics that moves with the tropical easterlies.
ECHO(ES)- This refers to radar returns such as precipitation echoes.
Polar front Transition zone between cold polar easterlies and mild midlatitude westerlies.
EasterliesAny winds with components from the east.Easterly WaveA low level disturbance of tropical origins. Easterly waves can develop into tropical cyclones.
