Numerical simulations of photochemical air pollution (CBM: Carbon-Bond Mechanism) under a theoretical three-dimensional local wind system are carried to clarify the fundamental characteristics of the effects of local wind on photochemical air pollution.
According to the AWS data of Pusan coastal area and KMA, the surface wind of Pusan during summertime showed a very remarkable land and sea breeze circulation. The ozone concentration distribution using local wind model showed that high ozone concentration zone near coastal area moved toward inland in the afternoon. This change implies a sea breeze increases the ozone concentration, but a land breeze decreases it in Pusan coastal area
