A supercell with "text-book" like features such as a well-defined hook echo on a radar scope and the precipitation core downwind of the wall cloud and rain free storm base.  2, fiche 1, Anglais, - classic%20supercell

Supercell [is] 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 [Tornado Vortex Signature]. 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. Storms exhibiting these characteristics often are called classic supercells; however HP(High Precipitation) storms and LP(Low Precipitation) storms also are supercell varieties.  3, fiche 1, Anglais, - classic%20supercell

The severe version of a worst-last storm is also a supercell type, and is either called a "classic supercell" (the standard supercell type) or an "LP (low-precipitation) supercell" - a dry-weather, high wind shear version. ... The classic supercell has a larger, darker appearance and accounts for most of the major tornado events everywhere.  4, fiche 1, Anglais, - classic%20supercell

Les orages de queue qui sont violents sont aussi de type supercellulaire; on les appelle des orages supercellulaires classiques ou à faibles précipitations (caractérisés par la présence d'air sec et d'un fort cisaillement du vent). [...] Les orages supercellulaires classiques sont de plus grande étendue et plus sombres; ce sont eux qui produisent la plupart des tornades, quelle que soit la région.  1, fiche 1, Français, - orage%20supercellulaire%20classique

A supercell thunderstorm in which heavy precipitation (often including hail) falls on the trailing side of the mesocyclone.  2, fiche 2, Anglais, - high%2Dprecipitation%20storm

High precipitation supercells... have a large precipitation core with heavy rains and possible hail. The rain can completely wrap an HP supercell tornado and obscure it from view on any side of the storm. Sometimes called HP’er.  5, fiche 2, Anglais, - high%2Dprecipitation%20storm

Precipitation often totally envelops the region of rotation, making visual identification of any embedded tornadoes difficult and very dangerous. Unlike most classic supercells, the region of rotation in many HP storms develops in the front-flank region of the storm (i.e.,usually in the eastern portion). HP storms often produce extreme and prolonged downburst events, serious flash flooding, and very large damaging hail events.  2, fiche 2, Anglais, - high%2Dprecipitation%20storm

Les orages supercellulaires à fortes précipitations sont observés le plus souvent dans le centre et le sud-est des États-Unis. On en voit à l'occasion en Ontario et au Québec, mais rarement dans l'ouest du Canada.  1, fiche 2, Français, - orage%20supercellulaire%20%C3%A0%20fortes%20pr%C3%A9cipitations

Orage supercellulaire (HP-haute précipitation). Un orage supercellulaire est un orage qui a une très forte précipitation (pluie et grêle) et qui inclut aussi un mésocyclone. La forte précipitation enveloppe et cache le mésocyclone (et possiblement une tornade) ce qui fait son identification difficile. Les orages supercellulaires produisent aussi des vents descendants très forts. Les fortes précipitations peuvent causer des inondation soudaines et peuvent aussi produire de la très grosse grêle.  2, fiche 2, Français, - orage%20supercellulaire%20%C3%A0%20fortes%20pr%C3%A9cipitations
