§        Results

This work allowed to isolate a great number of intense rain cells in the radar images (nearly 50 000 cells in 24 250 images), to study their existence-conditions and their behaviours near the Agglomeration, and to improve the existing procedure of storm alert of the Urban Community. These improvements were introduced in the operational system of real time radar data processing at the end of year 2002.
