摘要
利用1991～2000年福州市的探空、雨量和酸雨资料来探讨不同气象条件对降水酸度、酸雨出现率的影响,结果表明:雨量对降水酸度、酸雨出现率有着显著影响;逆温特征越明显,降水酸度越酸,酸雨出现率越大;1500m上空风对福州酸雨有着明显的影响;在暖平流控制下降水酸度不仅酸且酸雨出现率大;随着K指数增大,酸雨出现率逐渐减小。
The influence of acidity and acid rain frequency are discussed by using the data of sounding, rainfall and acid rain on meteorological conditions in 1991～2000 in Fuzhou, Fujian Province. The results show that rainfall is significant for the acidity and acid rain frequency. The more obvious the characteristics of inversion, the higher the acidity and acid rain frequency. Wind aloft in 1500 meters has significant effect on the acidity and acid rain frequency, which are higher when it is controlled by warm advection. Acid rain frequency decreases when K index rises.
