摘要
通过对 1999年 1月至 2 0 0 2年 10月南宁市酸雨观测数据进行统计分析 ,发现南宁市的酸雨频率较高 ,2 0 0 0年为 6 1 8% ;酸雨的酸度 (pH值小 )较大 ,其酸雨频率分布特征为夏半年较低 ,冬半年较高。将各季节酸雨分布状况与气象条件进行综合分析 ,发现其与地面和高空风向频率有很好的关系。
The acid rain observation in Nanning is analyzed.The results show that the acid rain frequence and the acidity in Nanning are both high, the frequency of acid rain in 2000 is 61.8%.The frequence is lower in summer half year and higher in winter half year. The relationship between acid rain and weather in different seasons is also analyzed. The seasonal distribution characters of acid rain have obviously relativity with the upper and surface wind direction freguency and the atmospheric circulation.
