摘要
分析了影响上海地区的高空气流输送轨迹。不同月份影响上海的高空气流来向不一。轨迹输送路径与天气系统的变化密切有关,且与上海地区出现的酸雨有关。研究表明,上海地区的酸雨,除与局地污染有关外,还与远处输送的外来污染有关。这些外来污染影响,主要来自上海西南向的北部湾和两广等地。也有部分来自东北——东方向的南朝鲜和日本西部地区。
In this paper, the upper air parcel trajectories of long-range transport in Shanghai were analyzed. The results indicated that the coming-direction of trajectories differed with different months. The transport track of trajectory was closely related to the synoptic system, and also related to acid rain occurred in Shanghai region.
Acid rain in Shanghai region do relate to both the influence of local pollutants and the influence of pollutants from other regions, These external pollutants may come from the southwest regions originated in Gulf Tonkin, Guangdong and Guangxi and the others from the northeast originated in South Korea and Ja-
