RETRIEVAL OF THE MICROPHYSICAL PROPERTIES IN A CASP STORM BY INTEGRATION OF A NUMERICAL KINEMATIC MODEL

A realistic kinematic model of cloud microphysical processes is presen ted. Heat and water substances in various phases are transported in th e model by specific horizontal and vertical velocities using a semi-La grangian numerical transport scheme. The model is applied to a CASP ca se study with horizontal and vertical velocities consistent with radio sondes and radar observations. The model is shown to capture the gener al observed features of the cloud and precipitation fields. In particu lar, it is shown that for the case studied stratiform clouds extend mu ch higher than the top of detectable precipitation. This numerical mod el constitutes a useful tool for understanding the life cycle of hydro meteors as a function of their position within the storm system.
