  2. Polar vortex - Wikipedia

    en.wikipedia.org/wiki/Polar_vortex

    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 ...

  4. How does the polar vortex lead to Arctic outbreaks?

    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 ...

  6. Atmospheric circulation - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_circulation

    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 ...

  7. Sudden stratospheric warming - Wikipedia

    en.wikipedia.org/wiki/Sudden_stratospheric_warming

    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 ...

    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.

  9. Polar high - Wikipedia

    en.wikipedia.org/wiki/Polar_High

    Closely related to this concept is the polar vortex, a rotating low-pressure circle of cold air around the poles. Surface temperatures under the polar highs are one of the coldest on Earth, with no month having an average temperature above freezing.
