中尺度气候分析对于了解城市热岛的结构是非常有用的。MM5模式由美国国家大气研究中心提供，是世界上主要的中尺度模式之一。然而，MM5中的地表参数化对于城市气候分析来说是比较粗糙的。也就是说，在MM5中，地表参数由每个网格中最优的土地利用来确定。但是，这种方法不能很好地表现城市的细部结构，忽略了绿地或水体对凉岛的影响。本文对MM5中的地表参数进行了修改，以表示土地利用比例。此外，MM5还考虑了人为放热的影响。
Meso-scale climate analysis is very useful to understand the structure of the urban heat island. MM5, provided by National Center for Atmospheric Research, is one of major meso-scale model in the world. However, parameterization of ground surface in MM5 is rather coarse to analyze urban climate. That is, in MM5, ground surface parameters are determined by most superior land-use in each mesh. However, this method is unable to represent detail urban structure, to say, the effect of Cool Island with green or water body is neglected. In this paper, ground surface parameterization in MM5 is modified to represent land-use fraction. Furthermore , effect of anthropogenic heat release is also incorporated in MM5.
