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 phenomena that have different sizes, structures, seasonal cycles, and impacts on weather.
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.
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 ...
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 devil.
Meteorologists typically classify vortex breakdown into three categories: major, minor, and final. No unambiguous standard definition of these has so far been adopted. [3] However, differences in the methodology to detect SSWs are not relevant as long as circulation in the polar stratosphere reverses. [10] "Major SSWs occur when the winter ...
As ominous as the term polar vortex sounds, meteorologists say the phenomenon is not new, nor despite its sound does it refer to a cyclone of cold or a freakishly dangerous storm. "The term 'polar ...
The south polar vortex was imaged again in 2013 and it was determined that the vortex forms higher up in the atmosphere than previously thought. The hazy atmosphere that Titan has leaves the moon unilluminated in the Sun's rays but the image of the vortex showed a bright spot on the south pole.
