Abstract

The region of Hiroshima is a coast position, which faces the Hiroshima bay. The diffusion of the air pollution material from the car traffic and the factory exhaust is a problem in this area. Air pollution in the coast regions strongly influenced about the sea breeze. A numerical model expressing the appropriate wind profile is necessary for a good pollution forecast. The characteristics of wind filed and the transport of heat at fine day in summer were examined by using AMeDAS data The relation between the sea breeze and the temperature was examined, at Hiroshima and Kabe. The simulation used HOTMAC was carried out for Hiroshima area, and The simulation products the good wind velocity and direction.
