Summary
| Description |
Français : Exemple idéalisé de vents obtenus par un radar Doppler. On voit la variation angulaire de la valeur du vents lorsqu'on se déplace le long d'un des cercles qui représente une équi-distance au radar sur un PPI, donc une équi-hauteur. Ce cas est celui d'un jet de vents de bas niveau de l'est-nord-est entre le niveau 18 et 25 (convention les vents entrants sont en bleu et ceux sortant sont en rouge).
English: Idealized output of wind velocities has analyzed by a Doppler radar which has a full coverage of targets over is domain. The value of velocities varies with angle of view of the beam as the radar its only noticing the radar component. In order to estimate the real wind, one has to find the angle at which the speed is maximized at a certain level above ground. In this case, the particles are moving from the North-East (Blue toward Red) near the radar and turning East as one look toward the outer ring. The rings indicate the height above ground and one notices that there is a variation of the maximum value according to the ring followed. The maximum velocities with height being between level 18 and 25. This is therefore the case of a low level jet from the NE. |
