Abstract
We introduced the two-parameter stratiform cloud model of Hu and Yan (1986) into the mesoscale model of Anthes et al.(1987),and reprogramed the latter,then constructed a three-dimensional stratiform cloud system model which includes three phases of water and detailed cloud physical processes.For the stability and accuracy of calculation in a larger time step,we accepted a set of hybrid-schemes for all and the time split scheme for some of the cloud physical processes,and proposed a parameterized method which calculates different types of phase change processes simultaneously,and designed the falling schemes of particles following the Lagrangian method.We used a dry model,a cumulus parameterization model,a two-phase explicit scheme model,and the model presented here to simulate two low-level mesoscale vortices,compared and analysed the simulating capability of these models.The results show that in simulation of the circulation structure of meso-vortex,the structure of cloud system,and surface precipitation,the model presented here is more reasonable and closer to the observations than other models.
