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.
