meteorology, the polar front is the weather front boundary between the polar cell and the Ferrel cell around the 60° latitude, near the polar regions, in both...

Antarctic Polar Front may refer to: The Antarctic Convergence, in oceanography The Polar Front commonly known as the "Antarctic Front", in atmospheric...

tropospheric polar vortex A circumpolar vortex, or simply polar vortex, is a large region of cold, rotating air; polar vortices encircle both of Earth's polar regions...

creation of a concentrated polar jet is the undercutting of sub-tropical air masses by the more dense polar air masses at the polar front. This causes a sharp...

within the polar air. The second is a "comma-shaped" signature that is found more frequently with systems closer to the polar front. Polar lows form for...

the polar highs around the 50th parallel of latitude. These extratropical convergence zones are occupied by the polar fronts where air masses of polar origin...

formation along the front and the low is positioned at the crest. Around the low, the flow becomes cyclonic. This rotational flow moves polar air towards the...

The polar bear (Ursus maritimus) is a large bear native to the Arctic and nearby areas. It is closely related to the brown bear, and the two species can...

The Antarctic Convergence or Antarctic Polar Front is a marine belt encircling Antarctica, varying in latitude seasonally, where cold, northward-flowing...

A weather front is a boundary separating air masses for which several characteristics differ, such as air density, wind, temperature, and humidity. Disturbed...
