Numerical Simulations of Long-Range Pollutant Transport from Coast to Inland Mountainous Regions

摘要

Kurita and Ueda (1986) presented an example of the long-range transport of pollutants which frequently occurs in summer in Japan light gradient wind conditions. High concentrations of photochemical oxidants were observed in late evenings in the mountainous region approximately 160 km northwest from the large industrial zone located along the Tokyo bay. Pollutants were apparently transported by the large-scale circulations produced by the combination of southwesterly valley winds induced by thermal lows located in the mountain ranges, and southerly sea-breeze circulations in the Pacific Ocean coastal region (Kurita et al., 1985). We wish to stimulate and evaluate the relative importance of these circulations by using a time dependent, three-dimensional mesoscale model, HOTMAC, High Order Turbulence Model for Atmospheric Circulations. 7 refs., 4 figs.
