Polar vortices also exist on other rotating, low-obliquity planetary bodies. [1] The term polar vortex can be used to describe two distinct phenomena; the stratospheric polar vortex, and the tropospheric polar vortex. The stratospheric and tropospheric polar vortices both rotate in the direction of the Earth's spin, but they are distinct ...
The polar vortex is a large storm that dwells in the middle and upper parts of the atmosphere and typically resides around the Arctic Circle.
The polar vortex is a gigantic, circular area of cold air high up in the atmosphere that typically spins over the North Pole (as its name suggests). The polar vortex is a gigantic, circular area ...
In fluid dynamics, a vortex (pl.: vortices or vortexes) [1] [2] is a region in a fluid in which the flow revolves around an axis line, which may be straight or curved. [ 3 ] [ 4 ] Vortices form in stirred fluids, and may be observed in smoke rings , whirlpools in the wake of a boat, and the winds surrounding a tropical cyclone , tornado or dust ...
AccuWeather forecasters break down the science behind the polar vortex and how it can influence the weather for locations thousands of miles away. While the name for this phenomenon may sound ...
Polar lows can be difficult to detect using conventional weather reports and are a hazard to high-latitude operations, such as shipping and gas and oil platforms. Polar lows have been referred to by many other terms, such as polar mesoscale vortex, Arctic hurricane, Arctic low, and cold air depression. Today the term is usually reserved for the ...
The polar vortex is a large area of low-pressure and cold air surrounding both of the Earth’s poles, according to the weather service. It always exists near the poles.
The polar cell is a simple system with strong convection drivers. Though cool and dry relative to equatorial air, the air masses at the 60th parallel are still sufficiently warm and moist to undergo convection and drive a thermal loop. At the 60th parallel, the air rises to the tropopause (about 8 km at this latitude) and moves poleward.
