Numerical Simulation of Microphysical Processes of Stratiform Clouds (II)—Microphysical Processes in Middle-latitude Cyclone Cloud Systems

Our cloud model (Paper I) was run to calculate the microphysical structures of clouds and pricipitation associated with middle latitude cyclones, by using the observed temperature and updaft as input. The results agree with observations in many aspects. The “seeder-feeder” mechanism, seeding by generating cells and warm rain process in shallow stratiform clouds have been demonstrated. The two-parameter model and the equations of ice nucleation, cloud-rain autoconversion and ice multiplication seem to be reasonable, but the equation of ice aggregation is not good enough
