Impact of Using the Urban Canopy Model on the Simulation of the Heat Island of Tokyo

We developed the urban canopy model and incorporated it into the WRF. The modified WRF was applied to simulate the urban heat island in order to estimate the impact of the urban canopy model. The modified WRF reproduced a nocturnal heat island of Tokyo,whereas the standard WRF failed to reproduce well. The result indicates that the urban canopy model can improve the numerical prediction for the local weather,and canopy effects are significant role of the formation of the nocturnal heat island. We are incorporating the urban canopy model into the latest version of the WRF.
