Physical modeling and analysis of rain and clouds by anisotropic scaling mutiplicative processes

Abstract

We argue that the basic properties of rain and cloud fields (particularly their scaling and intermittency) are best understood in terms of coupled (anisotropic and scaling) cascade processes. We show how such cascades provide a framework not only for theoretically and empirically investigating these fields, but also for constructing physically based stochastic models. This physical basis is provided by cascade scaling and intermittency, which is of broadly the same sort as that specificPby the dynamical (nonlinear, partial differential) equations. -from Authors
