Abstract :
A straightforward linkage between rain cell dynamics in terms of reflectivity Z (dBz) or its equivalent rain rate R (mm/h) and satellite or terrestrial radiolink attenuation can be performed. This work focuses on the presentation of an approach for assessing and characterizing rain cell dynamics based exclusively on the analysis of the radar reflectivity scans recorded in weather radar image, and without an a priori assumption on the structure of rain cells. This research has been addressed by using cellular automata. Rain cell dynamics are simulated by using probabilistic cellular automata rules and tracking vectors which indicate a global advection direction and velocity
