摘　　要：本文总结了本专题自1991年正式开展工作以来，围绕着专题的中心内容所做的研究工作结果。着重点放在有地形数值模式的改进和完善以及数值模拟试验这两个方面在模式的改进和完善方面，又着重介绍模式区域的拓宽、土壤下垫面的引入、海洋混合层模式和海洋表层流模式的建立和应用。在数值模拟试验方面，则主要介绍气压梯度力的新算法──“误差扣除法”及其模拟检验、包络地形试验、地形与大气湿过程对夏季风气候特征影响的试验、沙漠初始湿度对气候变化的影响试验、下垫面在气候变化中的作用试验以及海温异常的影响试验。没有在本文中介绍的数值试验结果，可参看本文集中作者等的其它论文。This paper summarizes the results of studies which we have carried out since 1991. The stress is put on two aspects of the improvements and developments of the numerical models with topography and numerical modelings. In the aspect of the model developments and improvements, the next studies are stressed, that is, the expension of the model, the inclusion of the underlying surfaces of different soil types, the developments and applications of the oceanic model. In the numerical modelings, we focus attention on the new computational scheme of the pressure gradient force - - the error subtraction scheme and its modeling checking, envelope orography experiments, experiments of the effects of the large topography and the atmospheric moist processes on the summer monsoon, the experiments of the effects of the initial desert moisture and the underlying surfaces on climate change, and experiments of the SSTA effects. The other experiments which are not included in this paper can be referred to the authors' papers in this collected works.
