Abstract
Outline of the transboundary air pollutant transport in Asia is presented. The detailed sulfate transport episode in winter was outlined as a typical anthropogenic pollutant and discussed the relationship between winter monsoon pattern (synoptic weather change) and frequency of transboundary air pollutant transport. As a natural aerosol transport, recent numerical modeling activities of spring yellow sand (Kosa) is also outlined and discuss the further development of chemical weather forecasting and its feasibility.
