Abstract

A long-range transport model including a detailed chemical reactions was applied to characterize the transboundary pollutant transport during both wintert and the Baiu season, and model results were compared with the aerosol high concentration observed in Tsushima, Chikugo-Ogori and Seoul in June 1991 and Feburary 1992. Long-range transport model results and backward trajectory analysis indicate that mesoscale phenomena such as synoptic scale high/low pressure change and the Baiu rainfront located between the southern part of China and the south of Japan island plays an important role for transportation the air pollutant emitted from China and Korean peninsula and for its transport/transformation to the northern Kyushu area It was revealed that the north-south movement of Baiu rainfront is significantly important for the aerosol high concentration over the Kyushu and western part of Japan area.
