Polar low Small, shallow depression which forms mainly in winter over some high-latitude seas within a polar or arctic air mass. Its motion is approximately the same as the air stream in which it is embedded.
Polar lows are defined as small but intense maritime meso-scale cyclones that form in cold polar or arctic air advected over relatively warmer water. Polar lows are much smaller and more transient than a regular mid-latitude depression.
Subpolar low A belt of low pressure located between 60° and 70° latitude. In the Northern Hemisphere, this "belt" consists of the Aleutian low in the North Pacific and the Icelandic low in the North Atlantic.
Subpolar low High-latitude, semipermanent cyclones marking the convergence of planetary-scale surface southwesterlies of midlatitudes with surface northeasterlies of polar latitudes; Icelandic low and Aleutian low are examples. ...
Polar low
Photos taken from man-made satellites have confirmed the existence of a type of cyclone which had not previously been documented. These polar lows are intense storms with high winds. NSIDC

Polar Lows can develop, and move (in the prevailing flow) with surprising speed, and lead to considerable dislocation of normal life in regions directly affected.
POLAR LOW - A small but intense vortex that develops at very high - near arctic (or low - near antarctic) latitudes as relativly cold air passes over warmer water.
North Atlantic Oscillation - the NAO is a large-scale fluctuation in atmospheric pressure between the subtropical high pressure system located near the Azores in the Atlantic Ocean and the sub-polar low pressure system near Iceland and is quantified ...
The NAO is a large-scale fluctuation in atmospheric pressure between the subtropical high-pressure systems located near the Azores in the Atlantic Ocean and the sub-polar low-pressure system near Iceland and is quantified in the NAO Index.
The travelling cyclones of subpolar latitudes usually reach maximum intensity in the area of the Aleutian low. The Aleutian low and its counterpart in the Atlantic Ocean, the Icelandic low, compose the Northern Hemisphere's subpolar low pressure ...
