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 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 ...
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 Crow instability of a jet aeroplane's contrail visually demonstrates the vortex created in the atmosphere (gas fluid medium) by the passage of the aircraft. A key concept in the dynamics of vortices is the vorticity , a vector that describes the local rotary motion at a point in the fluid, as would be perceived by an observer that moves ...
In the upper atmosphere of the Ferrel cell, the air moving toward the equator deviates toward the west. Both of those deviations, as in the case of the Hadley and polar cells, are driven by conservation of angular momentum. As a result, just as the easterly Trade Winds are found below the Hadley cell, the Westerlies are found beneath the Ferrel ...
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 northern hemisphere and the southern hemisphere each have a polar jet around their respective polar vortex at around 30,000 ft (5.7 mi; 9.1 km) above sea level and typically travelling at around 110 mph (180 km/h) although often considerably faster. [2] Closer to the equator and somewhat higher and somewhat weaker is a subtropical jet. [2]
