Abstract: Based on a five-layer primitive equations model with P-σincorporated coordinates and topograph designed by Qian et al., an one-way nested fine mesh limited area model was developed.It was statistically verified and compared with MM4 in terms of results of the same evolutional process of synoptic situation for Typhoon Wayne to assess the forecast skill.The result shows that the model relatively well predicts the actual situation,with correlative coefficients exceeding 0.74 between the forecast and observation for all layers of geopotential height. Both having good reflection of atmospheric reality,difference in the detail rather than the nature is found between the fine-mesh model and MM4 with respect to the temperature and pressure. The former gives weaker winds but better rainfall area prediction as compared to MM4;it is closer to the reality in the forecast of the amount of rainfall centers.
