Summary edit
| Description |
English: On the left side of each image, the direction and the speed of the environmental wind is shown by arrows. Horizontal vorticity produced by the shear in the lowest levels is tilted into updraft creating cyclonic (+) and anticyclonic (-) vertical vorticity on south and north side of storm. Dynamic low pressure in response to rotation enhances updraft. Rain causes downdraft in middle which splits storm in 2. For a right (left) moving storm, cyclonic rotation is in updraft (downdraft) and anticyclonic rotation is in downdraft (updraft) with tight reflectivity gradient (inflow flank) on south/east (north) side of storm.
Français : À gauche de chaque image, la force et la direction des vents avec l'altitude sont indiquées par des flèches. Le tourbillon horizontal créé par le cisaillement des vents près du sol est rendu vertical par le courant ascendant dans un orage supercellaire avec une branche cyclonique (+) montante et une autre anticyclonique (-) descendante. Une dépression dynamique se forme en altitude en réponse à la rotation et étire le tube, augmentant sa rotation. La pluie formée dans le nuage produit ensuite un courant descendant qui divise la cellule en 2. L'orage de droite se retrouve avec la rotation cyclonique dans son courant ascendant et une branche anticyclonique dans ses précipitations. Le gradient de réflectivité au radar est intense entre ces deux courants. |
