Polar cyclone - Simple English Wikipedia, the free encyclopedia
Polar cyclones (also known as Arctic Cyclones) are large areas of low pressure. They should not be confused with polar lows since people happen to use the same term for polar cyclones. Polar cyclones are usually 1,000 to 2,000 kilometers wide in which the air is moving in a spiral counterclockwise fashion in the northern hemisphere .
Polar vortex | Meteorology, Climate Change, Arctic Weather
Learn about the polar vortex, a large area of persistent low pressure and cold air above each pole, and how it can cause cold waves and disruptions in the jet stream. Find out how the polar vortex over Antarctica differs from the one over Arctic and how it affects the ozone hole.
Cyclone - Wikipedia
A cyclone is a large air mass that rotates around a low-pressure center, with inward-spiraling winds. Learn about the different types of cyclones, such as extratropical, tropical and mesocyclones, and how they form and develop.
Polar vortex - Wikipedia
The stratospheric polar vortex is an area of high-speed, cyclonically rotating winds around 15 km to 50 km high, poleward of 50°, and is strongest in winter. It forms during autumn when Arctic or Antarctic temperatures cool rapidly as the polar night begins.
