On a stochastic description of the time-space behaviour of extratropical cyclonic precipitation fields (Q1111844)

A stochastic description is developed for extratropical cyclonic precipitation fields at synoptic and meso scales as they are typically observed by radars over the Earth. This description attempts to account I) for the synoptic scale behaviour of a cyclonic storm (its birth, its synoptic scale motion trajectory, and its dissipation; II) for the synoptic-scale organizational structure of sub-synoptic precipitation areas (rainbands, precipitation cores and raincells) within a cyclonic storm; and III) for the behavior of subsynoptic precipitation areas, in terms of their births, their spatial configuratin evolutions, their motions, and their deaths (dissipation). The precipitation cores and the raincells are taken as the building blocks of the subsynoptic precipitation areas within a cyclonic rainfield.
