A Large Eddy Simulation Model for Convective Boundary Layer
一个对流边界层大涡模式的建立与调试

The method of large eddy simulation (LES) is an important numerical method for studying phenomena in the atmospheric boundary layer. In this paper, a new LES model and its evaluation is persented. This model is established on consideration of its simplicity and of saving computation time.Ef forts are also exerted to keep this model reasonable in principle. Application of this model to simulate horizontally homogeneous convective boundary layer shows reasonable results. The simulation also shows that the model can be used to problems of a rather coarse resolution. It is also possible to apply further this model to more practical conditions.
