摘要
在五层ｐ－σ混合坐标原始方程模式的基础上，改进成了一个九层ｐ－σ混合坐标原始方程模式。模式为１７×３９个格点，分辨率为５°×５°，其物理过程与五层模式相同。该模式性能稳定，用该模式对１９９４年冬的一次寒潮过程进行了模拟，温压场的主要特征符合实况。由于该模式的垂直分辨率高于五层模式，所以模拟结果优于后者，试验表明模式可应用于业务预报。
The five-layer primitive equation model with mixed p-σ coordinates is improved as a nine-layer model. The model has 17×39 grids with resolution of 5°×5°. Its physical processes are identical with the five-layer model. The model runs stably. We utilize this model to simulate a cold wave process during the beginning of the winter in 1994. The simulated pressure and temperature field characteristics are in agreement with the observations. The simulated results are better than that of five-layer model due to the higher vertical resolution. The experiments show that the model can be applied to operational prediction.
