Abstract: By use of the model developed in reference1,the simulations of severe storm,winter flow and snowfall over a mountain,as well as mountain-valley wind and sea breeze were performed.Different functions of the model were verified through the computation and the results were similar to that of observations,conceptual model,and simulations by other authors.It was shown that the model was applicable for various local and regional weather processes in respect of their inner structure,interaction with environment,and orographic and underlying forces.In addition,some important characteristics and mechanisms of the processes were also analyzed.
