  2. Upper tropospheric cyclonic vortex - Wikipedia

    en.wikipedia.org/wiki/Upper_tropospheric...

    Satellite image of an upper tropospheric cyclonic vortex in the western North Pacific. An upper tropospheric cyclonic vortex is a vortex, or a circulation with a definable center, that usually moves slowly from east-northeast to west-southwest and is prevalent across Northern Hemisphere's warm season.

  3. 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.

  4. Cold-core low - Wikipedia

    en.wikipedia.org/wiki/Cold-core_low

    Image of an upper tropospheric cyclonic vortex in the western North Pacific, a cold-core low. A cold-core low, also known as an upper level low or cold-core cyclone, is a cyclone aloft which has an associated cold pool of air residing at high altitude within the Earth's troposphere, without a frontal structure.

  5. Mesocyclone - Wikipedia

    en.wikipedia.org/wiki/Mesocyclone

    A mesoscale convective vortex (MCV), also known as a mesoscale vorticity center or Neddy eddy, [9] is a mesocyclone within a mesoscale convective system (MCS) that pulls winds into a circling pattern, or vortex, at the mid levels of the troposphere and is normally associated with anticyclonic outflow aloft, with a region of aeronautically ...

    Brutal winters may be in store for the portions of North America as the polar vortex continues to weaken and shifts, according to a new study. Weakening polar vortex may yield longer, harsher ...

  7. The Polar Vortex Explained

    www.aol.com/news/polar-vortex-explained...

    The polar vortex is a whirling cone of low pressure over the poles that's strongest in the winter months due to the increased temperature contrast between the polar regions and the mid-latitudes ...

  8. Cyclone - Wikipedia

    en.wikipedia.org/wiki/Cyclone

    A waterspout is a columnar vortex forming over water that is, in its most common form, a non-supercell tornado over water that is connected to a cumuliform cloud. While it is often weaker than most of its land counterparts, stronger versions spawned by mesocyclones do occur.

  9. Cyclonic vortex - Wikipedia

    en.wikipedia.org/wiki/Cyclonic_vortex

    Cyclonic vortex may refer to: Upper tropospheric cyclonic vortex, a vortex that usually moves slowly from east-northeast to west-southwest, and generally does not extend below 20,000 feet in altitude. Low-level tropospheric cyclonic vortices are known as low-pressure areas
