  2. Mesovortex - Wikipedia

    en.wikipedia.org/wiki/Mesovortex

    A mesoscale convective vortex (MCV) is a low-pressure center within a mesoscale convective system (MCS) that pulls winds into a circling pattern, or vortex. With a core only 30 to 60 mi (48 to 97 km) wide and 1 to 3 mi (1.6 to 4.8 km) deep, an MCV is often overlooked in standard surface observations . [ 7 ]

  3. Mesoscale convective system - Wikipedia

    en.wikipedia.org/wiki/Mesoscale_convective_system

    A mesoscale convective vortex--(MCV)--is a mid-level low-pressure center within an MCS that pulls winds into a circling pattern, or vortex. Once the parent MCS dies, this vortex can persist and lead to future convective development.

  4. Mesoscale convective complex - Wikipedia

    en.wikipedia.org/wiki/Mesoscale_convective_complex

    A mesoscale convective complex (MCC) is a unique kind of mesoscale convective system which is defined by characteristics observed in infrared satellite imagery. They are long-lived, often form nocturnally, and commonly contain heavy rainfall , wind , hail , lightning , and possibly tornadoes .

  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 ...

    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).

  7. Mesoscale meteorology - Wikipedia

    en.wikipedia.org/wiki/Mesoscale_meteorology

    A meso-beta scale vortex. Mesoscale meteorology is the study of weather systems and processes at horizontal scales of approximately 5 kilometres (3 mi) to several hundred kilometres. It is smaller than synoptic-scale systems (1,000 km or larger) but larger than microscale (less than 1 km).

    Parts of the United States are seeing temperatures ranging 20-25 degrees above average due to the vortex.

    Shallow convection – Occurs when convective instability exists, but no convection occurs; Shear – Wind shear – Winds aloft, often measured in knots. Shear funnel – Brief, often weak funnel generated by shear in a thunderstorm. Shelf cloud – Generally associated with strong thunderstorms, found along the leading edge. Horizontal and ...
