本文回顾了嵌套网格预报模式中有关侧边界处理的理论与技术,在此基础上提出了C型跳点网格单向影响侧边界的嵌套计算方案。并提出了进行侧边界方案对比试验的设想。

The theory of computational physics associated v, ith the lateral boundary problem of the nested limited-area model has been reviewed in this paper at first.Then the some popular techniques for the lateral boundary treatment current available for the research models as well as the operational models are introduced briefly. Basedon the review of previous studies and the features of our model a numerical scheme is prope and for the one-way the model with C-type staggered grids. It is also discussed in this peper hew to can pare the lateral boundary sehemes to select the oprimam one.
