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

Cumulus clouds with little or no vertical development characterized by a generally flat appearance. Their growth is usually limited by a temperature inversion, which is marked by the unusually uniform height of the clouds.  4, fiche 3, Anglais, - cumulus%20humilis

Record number: 3, Textual support number: 1 CONT

Fair Weather Cumulus. These clouds have the appearance of floating cotton with a flat base and distinct outlines, while having a lifetime anywhere from 5-40 minutes. The color shading ranges from white to light gray, with bases that can be as low as 1, 000 m above the ground, and have a diameter of about a kilometer or so. The cloud tops, likewise, are usually not very high and designate the limit of the rising air. Called cumulus humilis, these clouds show only slight vertical growth. However, given suitable conditions, what may initially begin as harmless Fair Weather Cumulus, can later develop into towering cumulus clouds that have an appearance resembling that of a cauliflower, with strong updrafts and possibly precipitation.  3, fiche 3, Anglais, - cumulus%20humilis

Record number: 3, Textual support number: 2 CONT

... when cumulus clouds have only slight vertical ascent and are usually confined to the lowest 2 kilometers of the atmosphere they are referred to as cumulus humilis; when cumulus clouds reach moderate vertical extent (generally between 2 to 6 kilometers above the ground) an exhibit small protuberances they are termed cumulus mediocris; finally, when cumulus clouds extend high up into the atmosphere (generally 6 kilometers or more above the ground) and their bulging parts resemble cauliflower they are called cumulus congestus.  5, fiche 3, Anglais, - cumulus%20humilis

Cumulus peu développé en hauteur et comme aplati. On l'observe généralement par beau temps.  3, fiche 3, Français, - cumulus%20humilis

Record number: 3, Textual support number: 1 CONT

Cumulus humilis. Ces nuages poussent tous à la même hauteur et donnent l'impression d'un champ de choux-fleurs dans le ciel. Le cumulus humilis est le plus petit des cumulus (en latin, humilis signifie humble). Il se forme lorsque la convection est faible. Sa faible hauteur et sa base aplatie sont des signes de beau temps. La hauteur de la base correspond au niveau de condensation. C'est-à-dire que l'air est relativement sec en-deçà de cette hauteur et est saturé au-delà. Le faible développement vertical indique que l'atmosphère est stable près du sommet du nuage, empêchant sa croissance. Les humilis sont plus larges que hauts.  4, fiche 3, Français, - cumulus%20humilis
