摘要
用降雨时的气流输送轨迹,分析了上海、重庆和贵阳三地的酸雨特点和成因。研究表明,重庆和贵阳的酸雨,主要是受局地污染源的影响,远距离外来污染影响不大;但贵阳在静止锋天气时的酸雨,可能也受远处输送来的外来污染的影响。上海地区的酸雨,除受局地污染源的影响外,还受远处外来污染的影响。
In rainy days, analyses of characters and origins of acid rair by using air parcel trajectories of transport in Shanghai, Congqing and Guiyang indicated that the origins of acid rain in Congqing and Guiyang were chiefly related to the local pollutants, but not too much to long-range pollutants from other regions. Acid rain associated with stationary frontal system in Guiyang probably might he related to the influence of external pollutants. Acid rain in Shanghai region do relate both to the influence of local pollutants and the influence of long-range external pollutants.
