摘　　要：厦门市是我国酸雨控制区之一。文章利用1992～2005年厦门市的探空、降水量和酸雨资料来分析厦门市不同气象条件对降水酸度、酸雨出现率的影响,分析结果表明:(1)不同等级的降水对降水酸度和酸雨出现率有明显影响,相对于夏、秋二季,冬、春二季的降水酸度更酸,酸雨出现率更高。(2)K指数、850～700hPa层的冷暖平流对酸雨污染没有明显影响。(3)酸雨出现率随着1500m高空风速的增大而增多,风向变化对降水酸度和酸雨出现机率的影响不大。(4)逆温对酸雨污染的有一定的影响。Xiamen is one of the cities in the acid rain control zone in China. Based on the sounding data, precipitation data and acidity of everyday in Xiamen city from 1992 to 2005,the influence of different weather conditions on precipitation acidity and the rate of occurrence of acid rain are analyzed.Results indicate that the precipitation acidity and the rate of occurrence of acid rain vary with the rainfall of different classes, and they are also more higher in winter and spring than that in summer and autunm.K index and the cold or warm advection on 850 hPa to 700 hPa level have no clear influent on the acid rain pollution. The rate of occurrence of acid rain increases when the wind speed on 1500 meter become larger, while the wind direction has little effect on the precipitation acidity and the rate of occurrence of acid rain.The temperature inversion has some effect on the acid rain pollution.
