| 摘 要： | 1993和1994年在辽宁凤凰山夏季进行了2次降水观测研究,两次都发现该地区出现了较强的酸雨,降水pH均值分别为4.71和4.54?进行了后推气流轨迹的计算,首次证明,该地区的酸雨形成明显地受到朝鲜半岛和日本的影响?由于该地区降水集中在夏季,而丹东地区夏季又盛行东南风,因此该地区酸雨形成的外部输送影响是重要因素?

| Abstract: | field measurements of acid precipitation at Fenghuan Mountain and the calculation of air trajectory were conducted in the summer of 1993 and 1994.The volume weighted average pH value of serious acid rain in 1993 is 4 71 and that in 1994 is 4 54.The calculation,in the first time,shows that the acid rain in this area is evidently suffered the effects from Korea Peninsula and southern Japan. Because the rainfalls are concentrated in summer in this area and the prevailing wind direction at the same time is southeast.So the transportation effects from outside is an important factor for the formation of acid ran in this area. |
