中文摘要: 通过对广西主要城市近13年酸雨观测的数据统计分析,发现广西的酸雨频率较高,酸雨的酸度较大(即pH值小),pH<4.5强酸性降雨的频率也较高。季节变化特征为夏半年酸雨频率较低,冬半年酸雨频率较高。广西酸雨形成与大气环流密切相关,经分析造成广西酸雨的天气系统主要是高空槽、切变线和锋面,约占广西酸雨的76%,而其它天气系统造成的酸雨所占的比例为24%。
中文关键词: 酸雨，频率，大气环流
Abstract: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.
