    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 meteorology - Wikipedia

    en.wikipedia.org/wiki/Mesoscale_meteorology

    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).

  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 ...

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

  7. 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 .

    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).

  9. What you need to know about the polar vortex

    " The polar vortex is defined as a mass of cold air that is tightly bound to polar regions by strong counterclockwise winds known as the polar jet stream," Thornton explained.
