  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. 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.

  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. 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 ]

    en.wikipedia.org/wiki/2013_Washington,_Illinois...

    The supercell developed a mesocyclone and maintained it for over 50 miles (80 km). [10] Then, at 10:52 am CDT, the supercell produced a strong but short-lived EF2 tornado over at Pekin. The tornado touched down north of State Highway 9, mainly uprooting trees and downing power lines before it crossed the Illinois River. The tornado made it ...

  8. 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]

  9. 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.
