A RETRIEVAL OF THERMODYNAMIC AND MICROPHYSICAL VARIABLES BY USING WIND DATA IN SIMULATED MULTI-CELLULAR CONVECTIVE STORMS

A retrieval method applicable to precipitating storms, which are trans ient or include complicated physical processes is presented. An imagin ary situation is assumed that environmental fields of temperature and moisture and time sequence of the wind field are known by the observat ions of upper soundings and dual- (or more) Doppler radars. In this me thod, equations of thermodynamic and microphysical (scalar) variables are time-integrated by imposing these data. First, the performance of this method is examined by application to the results of numerical sim ulations of a quasi-periodic multi-cellular storm. It is shown that a time sequence of the wind field is necessary, which is sampled with a time step resolving transient features of the storm, to retrieve scala r fields well. This method is further applied to an aperiodic multi-ce llular storm and a quasi-periodic multi-cellular storm having a compli cated ice-phase process. Retrieved results attained in both cases are satisfactory.
