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 typical cyclone is illustrated in Figure 6 [p. 15]. Dust-laden gas tangentially enters the annular space between the cyclone body and the outlet tube, and begins to traverse a helical path(shown by the solid flow line) called the "main vortex". Near the bottom of the cone, the axial direction of the helix reverses, as shown by the dotted line, and forms the "vortex core". The tangential velocity is greatest at a radial distance from the centerline of 0. 4 to 0. 8 the radius of the gas outlet tube. The diameter of the vortex core is usually 0. 2 to 0. 4 times the diameter of the gas outlet. The tangential direction of flow is the same in both the main vortex and the vortex core, so that centrifugal separating forces are exerted on the particles in both sections of flow.  1, fiche 3, Anglais, - main%20vortex
