| 摘 要： | A 2-D slab-symmetric model of mixed convective-stratiform cloud is developed bysuperimposing convective cloud-size field on the convergence field,in order to simulate and studythe mixed clouds consisting of stratiform cloud and convective cloud.A deep convective,anelasticand conservative system of equations with basic variables(V,θ,π')is solved by a new method tocalculate dynamic field.The water substance in the cloud is divided into 6 categories and themicrophysical processes are described in spectrum with two variable parameters and morereasonable particle number/size distributions.To compare with measured radar echo intensity andstructure,the model may calculate echo intensity of the model cloud observed by radar.
