Summary
| Description |
Français : Principle de la double polarisation utilisée en radar. Une gouttelette prend une forme oblate quand elle augmente de masse et les ondes polarisées horizontalement et verticalement donneront des échos d'intensités différentes en revenant au radar. D'autre part, la grêle est plus ou moins circulaire et donc les retours seront égaux. D'autres objets ont des axes préférés. En comparant les retours verticaux et horizontaux avec d'autres données radars, il est possible d'estimer directement le type de cibles vues par le radar. English: Principle of polarization use for radar. As water dropplets are usually oblate (flattened) as they become larger, the horizontally polarized wave will have a stronger return than the vetical one. Hail on the other hand has no preferred axis. Comparing the V and H returns will thus give information on the shape of the weather echos and on its type when combined with other data like reflectivity. |
