... a Doppler radar velocity pattern that indicates a region of intense concentrated rotation.  1, fiche 1, Anglais, - tornadic%20vortex%20signature

Record number: 1, Textual support number: 1 CONT

The tornadic vortex signature(TVS) appears on radar several kilometers above the ground before a tornado touches ground. It has smaller, tighter rotation than a mesocyclone. While the existence of a TVS does not guarantee a tornado, it does strongly increase the probability of a tornado occurring.  1, fiche 1, Anglais, - tornadic%20vortex%20signature

[Une signature tornadique de rotation est] un mésocyclone intense détecté par un algorithme qui analyse les données Doppler d'un radar météorologique. Cette signature indique la possibilité de la présence d'une tornade sous l'orage associé.  3, fiche 1, Français, - signature%20tornadique%20de%20rotation

STR : L'abréviation TVS fait référence au terme anglais; il vaudrait mieux adopter une abréviation qui correspond au terme français, soit STR pour «signature tornadique de rotation».  2, fiche 1, Français, - signature%20tornadique%20de%20rotation

TVS : Certains auteurs utilisent l'abréviation TVS au masculin. Elle doit toutefois être utilisée au féminin puisqu'elle fait référence à la signature tornadique de rotation.  2, fiche 1, Français, - signature%20tornadique%20de%20rotation

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
