摘　　要：利用1992-2005年邵武市的探空、降水量和酸雨资料,分析了邵武市不同气象条件对降水酸度、酸雨出现率的影响,结果表明:(1)闽西北是福建省酸雨污染较严重的地区之一,相对于夏、秋二季,冬、春二季的降水酸度更强、酸雨出现率更高。(2)降水的量级对降水酸度、酸雨出现率有明显影响。(3)逆温层对酸雨有较大的影响,逆温特征越明显,降水pH值越低,酸雨出现概率越大。(4)1500 m高空风速、风向在一定程度上影响邵武市降水酸度和酸雨出现机率。(5)邵武市上空850 hPa^700 hPa高度层在暖平流控制下不仅降水酸度强且出现酸雨的机会大。相反,如果850hPa^700 hPa高度层在冷单流控制下不仅降水酸度弱且出现酸雨的机会小。Using the sounding data of rainfall and acid rain in Shaowu from 1992 to 2005,the influence of meteorological conditions on acidity,frequency of acid rain were analyzed.The results showed as follows:(1)The North-west of Fujian Province was one of the serious areas of acid rain pollution,the acidity and frequency of acid rain were more distinct in winter and spring than in summer and autumn.(2)Rainfall was significant for the acidity and frequency of acid rain.(3)The influence of inversion on acid rain were ...
