The largest thunderstorms that approach a steady-state internal structure for a few hours and are able to produce large hail and tornados. The NWS defines supercells as thunderstorms that have a persistent, rotating updraft as part of their structure - these rotating updrafts have the potential to spawn deadly tornados.
a large, rotating severe thunderstorm
a large thunderstorm whose updrafts and downdrafts are
an organized thunderstorm that contains a very strong, rotating updraft
a rotating thunderstorm which can produce one or more tornadoes
a strong thunderstorm that contains a deep, persistant rotation within the updraft
Name applied to a severe thunderstorm of massive size. Supercells are more persistent than a normal thunderstorm and are much more likely to produce a tornado.
A violent thunderstorm which last for several hours, sometimes causing torrential rain and tornadoes.
A bad storm involving air moving vertically. These storms often produce severe weather - hail, straight-line winds and violent tornadoes.
A severe thunderstorm whose updrafts and downdrafts are in near balance allowing the storm to maintain itself for several hours. Supercells often produce large hail and tornados.
A violent thunderstorm that has a persistent, rotating updraft and is capable of spawning tornadoes
A highly organized thunderstorm with a rotating updraft, known as a mesocyclone. It poses an inordinately high threat to life and property. Often produces large hail, strong winds, and tornadoes.
A relatively long-lived thunderstorm with a persistent rotating updraft. Supercells are rare, but are responsible for a remarkably high percentage of severe weather events-especially tornadoes, extremely large hail, and damaging wind storms.
A thunderstorm with a persistent, rotating updraft. The rarest thunderstorm type, the supercell, produces the most violent weather including the most significant tornadoes, giant hail, deadly lightning and damaging microburst winds. The supercell thunderstorm is the primary target of StormStock photographers. Also mesocyclone.
(or Supercell Storm) - a violent thunderstorm which can produce hail and large tornadoes and containing updrafts and downdrafts that are nearly in balance, allowing it to maintain itself for several hours
A thunderstorm with a persistent rotating updraft. Supercells are rare, but are responsible for a remarkably high percentage of severe weather events - especially tornadoes, extremely large hail and damaging straight-line winds. They frequently travel to the right of the main environmental winds (i.e., they are right movers). Radar characteristics often (but not always) include a hook or pendant, bounded weak echo region ( BWER), V-notch, mesocyclone, and sometimes a TVS. Visual characteristics often include a rain-free base (with or without a wall cloud), tail cloud, flanking line, overshooting top, and back-sheared anvil, all of which normally are observed in or near the right rear or southwest part of the storm ( Fig. 7). Storms exhibiting these characteristics often are called classic supercells; however HP storms ( Fig. 3) and LP storms ( Fig. 5) also are supercell varieties.
A severe thunderstorm characterized by a rotating, long-lived, intense updraft. Although not very common, they produce a relatively large amount of severe weather, in particular, extremely large hail, damaging straight-line winds, and practically all violent tornadoes.
A supercell is a severe thunderstorm with a deep rotating updraft (a mesocyclone).http://www.stormchasers.au.com/lemon7.htm Supercell thunderstorms are the largest, most severe class of single-cell thunderstorms. It has been argued that there are really only two types of thunderstorms: supercell and ordinary, though some have four classifications: single-cell, multi-cell, squall line, and supercell.
