Abstract In this study, the relationship between urban size and heat island intensity is analyzed using the meso-scale sWeather Research & Forecasting (WRF) model, and is applied to three different sized cities (Tokyo, Osaka, and Nagoya). Given that the urban areas of the study region spread inland, there were a number of high temperature points, with air temperature tending to be relatively higher in Tokyo. The spatial average air temperature in urban areas rise with the expansion of the urban size, since higher air temperature areas increase inland. In the case of calculating the heat island intensity using spatial average temperatures in urban areas, the heat island intensity is related to urban size.
