Incorporating an urban canopy model to represent the effects of buildings: Development of urban climate analysis model using MM5 Part 2

Urban heat island phenomena have been analyzed by numerous researchers using mesoscale meteorological models. Although there are many mesoscale models, MM5 is considered one of the major mesoscale models. In such analysis, a one-dimensional heat balancemodel is primarily used for surface boundary conditions. However, it is necessary to include the effect of the building canopy to analyze the thermal environment at pedestrian level. Therefore, MM5 is incorporated with the urban canopy model. The urban thermal environment in Kanto region is analyzed by means of the new method. The results show better agreement with observation data.
