Summary
DescriptionBaserefl composite comparison fr.svg
English: Reflectivity on the PPI low level of a NEXRAD weather radar on the left and Composite reflectivities on the right. The difference between the two shows precipitation at higher level not reaching the ground. In this case, the notches, at #1, the fuchsia-colored region, visible on the composite image, is all but missing on the base reflectivity. At #2 and #3, show more rain supported by strong updrafts.
Français : Comparaison de l'image des données de réflectivité radar d'un PPI de bas niveau à gauche et de la réflectivité composite dans la verticale à droite. La zone 1 montre de fortes intensités dans la colonne mais presque rien à bas niveau. Les zones 2 et 3 montre une colonne intense de précipitations due à un courant ascendant fort.
