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 2, Anglais, - classic%20supercell

Record number: 2, Textual support number: 1 CONT

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 2, 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 2, 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 2, Français, - orage%20supercellulaire%20classique

Funnel cloud is a condensation funnel extending from the base of a towering cumulus or Cb [cumulonimbus], associated with a rotating column of air that is not in contact with the ground (and hence different from a tornado). A condensation funnel is a tornado, not a funnel cloud, if either a) it is in contact with the ground or b) a debris cloud or dust whirl is visible beneath it.  8, fiche 3, Anglais, - tuba

The tornado and severe weather associated storm produce a recognizable radar echo structural organization resulting from an intense moist updraft. Some of these considerations are :... A low-level pendant exists generally perpendicular to the storm motion and beneath the echo overhang, or a bounded weak echo region(BWER) exists. This pendant may be absent in low precipitation supercells.  6, fiche 3, Anglais, - tuba

Il existe plusieurs variantes de tornades. Toutefois, on observe habituellement cinq étapes : la mise en place : une colonne d'air en rotation se développe au sein d'un cumulonimbus, puis se dirige vers le sol. Un nuage en forme d'entonnoir (le tuba) descend en tourbillonnant vers le sol; la naissance : en atteignant le sol, la colonne devient, par définition, une tornade [...]  4, fiche 3, Français, - tuba
