区域气候模式研究进展

Advances in Regional Climate Model Studies

全面回顾了区域气候模式的分类、发展和最新研究动态 ,指出区域气候模式研究有了长足的发展 ,其中重要的有 :加入雪盖、土壤水等作用的陆面过程 ,全球模式与区域细网格模式的嵌套由一维发展到三维 ,由一层发展到多层 ,发展了更加合理的参数化方案 ;但也存在许多不足 ,模式提供的植被资料与实情相差很大 ,对于沙漠地区的植被盖度的算法不尽合理 ,对次网格地形及对其湍流通量输送过程的刻画不够细致等。因此 ,建议利用遥感手段采用非线性方法 (如分形等 )对遥感资料施行反演 ,进行多尺度的双向模式嵌套。

The classification,development work and recent advances of regional climate models are reviewed comprehensively in this paper.Great advances in regional climate model have been made in the recent years.The main advances are:introduing snow-cover and soil-water into regional climate models;the development of the regional climate model nested in a general circulation model from 1D to 3D and from 1 layer to multi-layers;the development of more reasonable parameterization schemes.But there are still some defalts,such as,the inadequate calculation method of vegetation cover in desert,and rough depection in sub-grid topogtaphy and turbulent flux transfer etc.Therefore,nonlinear methods(fractal etc) for the retrieval of remote sensing date and the multi-scale two-direction nesting are suggesed to be used in future regional climate simulations.
