Match each description with the convective weather feature being described. short-lived thunderstorm with a dry line single updraft and downdraft contains a mesocyclone supercell thunderstormv induces strong straight line winds that propagate outward from thunderstorm microburst or downburs largest and longest lasting thunderstorm type derecho damaging straight line winds that propagate over considerable distance ordinary thunderstorm forms along a boundary between m CT and mT air mesoscale convective cvExplanation / Answer
1) supercell thunderstorm - short- lived thunderstorm with a single updraft and downdraft.
Supercell storms are large, usually severe, quasi-steady-state storms that form in an environment where wind speed or wind direction varies with height ("wind shear"), and they have separate downdrafts and updrafts.
2) mesoscale convective system - contains a mesocyclone
A mesoscale convective system (MCS) is a complex of thunderstorms that becomes organized on a scale larger than the individual thunderstorms but smaller than extratropical cyclones, and normally persists for several hours or more.
3)derecho - induced strong straight line winds that propagate outward from thunderstorm.
derecho is a widespread, long-lived, straight-line wind storm that is associated with a land-based, fast-moving group of severe thunderstorms.
Derechos can cause hurricane-force winds, tornadoes, heavy rains, and flash floods. Convection-induced winds take on a bow echo(backward "C") form of squall line, forming in an area of wind divergence in upper levels of the troposphere, within a region of low-level warm air advection and rich low-level moisture. They travel quickly in the direction of movement of their associated storms, similar to an outflow boundary (gust front), except that the wind is sustained and increases in strength behind the front, generally exceeding hurricane-force.
4) ordinary thunderstorm - largest and longest lasting thunderstorm type
5) dry line - damaging straight line winds that propagate over considerable distance.
6) microburst or downburst - forms along the boundary between cT and mT air.
