Circumpolar
Encyclopedia
The term circumpolar may refer to:
- circumpolar navigation: to travel the world "vertically" traversing both of the poles
- Antarctic region
- Antarctic CircleAntarctic CircleThe Antarctic Circle is one of the five major circles of latitude that mark maps of the Earth. For 2011, it is the parallel of latitude that runs south of the Equator.-Description:...
- the Antarctic Circumpolar CurrentAntarctic Circumpolar CurrentThe Antarctic Circumpolar Current is an ocean current that flows from west to east around Antarctica. An alternative name for the ACC is the West Wind Drift. The ACC is the dominant circulation feature of the Southern Ocean and, at approximately 125 Sverdrups, the largest ocean current...
- SubantarcticSubantarcticThe Subantarctic is a region in the southern hemisphere, located immediately north of the Antarctic region. This translates roughly to a latitude of between 46° – 60° south of the Equator. The subantarctic region includes many islands in the southern parts of the Indian Ocean, Atlantic Ocean and...

- Antarctic ConvergenceAntarctic ConvergenceThe Antarctic Convergence is a curve continuously encircling Antarctica where cold, northward-flowing Antarctic waters meet the relatively warmer waters of the subantarctic. Antarctic waters predominantly sink beneath subantarctic waters, while associated zones of mixing and upwelling create a zone...

, stars that never rise or set from the perspective of a given latitude on Earth. - Polar frontPolar frontIn meteorology, the polar front is the boundary between the polar cell and the Ferrel cell in each hemisphere. At this boundary a sharp gradient in temperature occurs between these two air masses, each at very different temperatures....
