| 摘 要： | This paper describes a two-dimensional slab-symmetric hailcloud model,of which dynamics almost con-tains all the dynamic factors.The model with the improved precipitation process included can show the bipara-meter change of particle size-distribution.A new suspending lateral boundary condition is proposed whichmay improve the influence of boundary on the airflow within computing domain.The subroutines designedfor studying the change in outline of precipitating particle region can describe the interaction between airflowand precipitation particles.With this model the structure of weak ccho region in hailcloud is simulatedand the airflow patterns under different thermal disturbances and wind shear are studied.
