• 摘要：本文介绍一种适用于区域污染并考虑了二氧化硫在输送过程中转化为硫酸盐和被地面吸收等过程的烟团模式。根据北京、天津和渤海地区六氟化硫实验提供的扩散参数及该地区气象资料(风向、风速)和污染源资科,用模式计算出该地区在西北风,东南风为主的气象条件下二氧化硫浓度分布,并与实测值做了比较。

• Abstract：A puff model which is available for mesoscale air pollution estimation has been developed taking into account the stability changes with time, the rate of transformation of SO₂ to sulfate as well as the rate of SO₂ removal at surface. Based on atmospheric dispersion parameters provided by SF6 tracer experiment conducted in Beijing-Tianjin area, meteorological data (wind speed and direction), and SO₂ emission sources, distribution of SO₂ concentrations under strong northwest or southeast wind dominating this area was computed and compared with the observed values.
