Urbanization has been well in progress accompanied by the change of land-use due to concentration of population and consumption of a lot of energy. In particular, large-scale reclamation projects have been constructed in the coastal areas in Japan. Such a tendency is found in the world that ‘heat island’ phenomena can be appeared in most of metropolitan cities because of the temperature difference between urban and rural areas. In the present study, therefore, the effects of urbanization and construction of reclaimed islands on the local climate are examined using a 15-levels-three dimensional atmosphere numerical model with highorder turbulence modelling.
