  2. Mesocyclone - Wikipedia

    en.wikipedia.org/wiki/Mesocyclone

    A mesocyclone is a meso-gamma mesoscale (or storm scale) region of rotation , typically around 2 to 6 mi (3.2 to 9.7 km) in diameter, most often noticed on radar within thunderstorms. In the northern hemisphere it is usually located in the right rear flank (back edge with respect to direction of movement) of a supercell , or often on the ...

  3. Supercell - Wikipedia

    en.wikipedia.org/wiki/Supercell

    A supercell is a thunderstorm characterized by the presence of a mesocyclone, a deep, persistently rotating updraft. [1] Due to this, these storms are sometimes referred to as rotating thunderstorms. [ 2 ]

  4. Mesovortex - Wikipedia

    en.wikipedia.org/wiki/Mesovortex

    A mesocyclone is a type of mesovortex, approximately 1 to 10 km (0.6 to 6 mi) in diameter (the mesoscale of meteorology), within a convective storm. [6] Mesocyclones are air that rises and rotates around a vertical axis, usually in the same direction as low pressure systems in a given hemisphere.

    The near 26 inches of rain at Fort Lauderdale-Hollywood International Airport was a 1-in-1,000-year storm.

  6. Rear flank downdraft - Wikipedia

    en.wikipedia.org/wiki/Rear_flank_downdraft

    Air circulation in a supercell thunderstorm, including the rear flank downdraft. The rear flank downdraft (RFD) is a region of dry air wrapping around the back of a mesocyclone in a supercell thunderstorm. [1] These areas of descending air are thought to be essential in the production of many supercellular tornadoes.

  7. Mesoscale convective system - Wikipedia

    en.wikipedia.org/wiki/Mesoscale_convective_system

    The supercell is the strongest of the thunderstorms, most commonly associated with large hail, high winds, and tornado formation. Precipitable water values of greater than 31.8 millimetres (1.25 in) favor the development of organized thunderstorm complexes. [6]

  8. Descending reflectivity core - Wikipedia

    en.wikipedia.org/wiki/Descending_reflectivity_core

    The relationship between descending reflectivity cores and tornadogenesis in supercell thunderstorms is a significant area of interest for meteorologists, given the potential of DRCs to influence storm dynamics and tornado formation. DRCs have been observed to impact the low-level wind fields in supercells, a critical factor in tornado development.

  9. Hook echo - Wikipedia

    en.wikipedia.org/wiki/Hook_echo

    A hook echo is a pendant or hook-shaped weather radar signature as part of some supercell thunderstorms. It is found in the lower portions of a storm as air and precipitation flow into a mesocyclone, resulting in a curved feature of reflectivity. The echo is produced by rain, hail, or debris being wrapped around the supercell. [1]
