| Abstract: | Abstract A realistic kinematic model of cloud microphysical processes is presented. Heat and water substances in various phases are transported in the model by specific horizontal and vertical velocities using a semi‐Lagrangian numerical transport scheme. The model is applied to a CASP case study with horizontal and vertical velocities consistent with radiosondes and radar observations. The model is shown to capture the general observed features of the cloud and precipitation fields. In particular, it is shown that for the case studied stratiform clouds extend much higher than the top of detectable precipitation. This numerical model constitutes a useful tool for understanding the life cycle of hydrometeors as a function of their position within the storm system. |
