東アジアスケールの超境大気汚染 Transboundary Air Pollutants Transport over the East Asia
To understand the observed characteristics of transboundary air pollutants transport over the East Asia, an atmospheric transport model which includes detailed chemical reactions, the STEM (Carmichael et al, ), was applied. It was found that wind pattern variations associated with a synoptic scale pressure system are extremely important for the transport of pollutants in this region. An on-line transport model coupled with Regional Atmospheric Modeling System (RAMS, Pielke <I>et al.</I>, ) are also applied during the rainy season (June). On-line transport model explained well the sulfate concentration variation, and indicates that the strong concentration gradients exists at the northern side of rainy meso-front (typically at Korea and Kyushu Japan). It was found that the location of rainy meso-front plays an important role for sulfate concentration level in Japan and Korea.
