Analysis of Effect of Atmosphere Circulation on Acid Rain in Guangxi

Based on the data of acid rain in the main cities of Guangxi ,the result shows that the acid rain frequency in Guangxi is high and its acidity is strong which means pH value is low. The frequency of strong acid rain whose pH is lower than 4.5 is high too, acid rain frequency is relative low in summer half year while relative high in winter half year. The conclusion are also drawn that acid rain has relation with atmosphere circulation, 76 percents of acid rain in Guangxi has relation with weather system of height trough, shear and frontogenesis, while 24 percents of acid rain has relation with others weather systems.
