Summary
[edit]
| Description |
Français : Voici trois types de circulations a très petite échelle (méso): rotation, convergence et divergence des vents. Dans la colonne de gauche on voit les vecteurs vents et à droite la composante radiale vue par le radar qui se trouve en bas de l'image (bleu-vert vers le radar et rouge-jaune s'en éloignant). À l'extrême droite on voit un mélange de convergence et de rotation typique d'un mésocyclone. Remarquez l'axe de la vitesse nulle dans chacun des cas.
English: How a Doppler radar would see three types of mesoscale circulations: rotaton, convergence and divergence. On the left, the velocity vectors in those circulations and on the right the radial component to the radar (at the bottom) that is perceived (blue toward, red away). A mesocyclone is usually a mix of rotation and convergence into the updraft so it would be seen as the doublet of the extreme right. Norice the axis of the zero velocity line. |
