| 摘 要： | A fine-mesh numerical model with thirteen-layer, three-dimensional primitive equation is designed, which has a relatively high vertical resolution in the boundary layer and detailed boundary parameterization. A strong cold frontal process is simulated by the model. Comparison of the simulated results of this process with different models shows that the result of this model is prior to that of others, and that it is necessary to increase the vertical resolution and to take account of the physical processes in the boundary layer.
