| 摘 要： | 为了提高差分模式的分辨率,以改进台风路径预报。本文提出了原始方程模式的两种嵌套网格方案。试验表明,所提异模式嵌套网格交界域变量的衔接、协调处理是有效的;以轴对称正态分布模拟台风环流对于合风路径数值预报是适宜的。个例计算及1980年试用结果表明,套网格方案对路径预报有不同程度改进。

| Abstract: | In order to improve the prognosis of typhoon movement, the nested mesh schemes for the primitive equation models are presented in this paper. An experiment on prediction for some examples had been made by using these schemes. It is shown from the calculation that the methods for conjunction and adjustment of dependent variables at the juncture of coarse-mesh and fine-mesh are effective and the axial-symmetrical typhoon circulation simulated by the normal distribution is suitable for the prediction of typhoon movement by using numerical models. One of the schemes was tested during the typhoon season in 1980 and resulted in the improvement, to a certain degree, in the forecast of the typhoon tracks. |
