摘要
对中国区域气候变化的模拟和问题作了介绍和讨论。指出，由于大尺度大气环流模式和海气耦合模式模拟结果的不确定性，有必要发展区域气候模式以用于区域气候变化的机理研究和预测试验。接着介绍了不同区域气候模式对１９９１ 年江淮流域严重洪涝的模拟结果，表明区域气候模式有较好的性能和前途。本文还论述了侧边界处理方案对模拟结果的影响。最后对当前区域气候模拟中存在的问题和解决的可能途径进行了必要的讨论。
Introductions and discussions are made in this paper on the modeling and problems of the regional climate changes in China. It is pointed out that the regional climate models are necessary to be developed in order to study the mechanisms of the regional climate changes and to predict these changes because the large scale general circulation models and the coupled atmosphere ocean models have uncertainties in their modeling results. The simulation results of the floods in 1991 happened in the Changjiang and Huaihe Basins are introduced, and it is found that the capacities of the regional climate models are fairly good and they have promising prospects. It is further discussed of the treatment schemes of the lateral boundary conditions and their impacts on the modeling results. At last, the problems in the regional climate modeling at the present and the possible solutions of those problems are necessarily discussed in this paper.
