摘要
通过对1992～2005年百色市酸雨观测数据进行统计分析，发现百色市的酸雨频率较高，酸雨的酸度（PH值小）较大，其分布特征为夏半年酸雨频率较小，冬半年酸雨频率较高。将各季节酸雨分布状况与气象条件进行分析，发现与地面和高空风向频率、大气环流特征、大气层结稳定度等关系密切。显然，桂西酸雨污染不仅与污染源有关，还与气象条件关系密切。
Basing on the acide rain observations from 1992 to 2005 in Baise city, the statistics shows that the acide rain frequency is more high with greater PH value. The distribution characteristics of acide rain frequency are lower （higher） during summer （winter）. According to the analysis of seasonal distribution characteristics of acide rain and the weather conditions, wind direction frequency of surface and high has close relation to Synoptic Circumfluence and atmospere stability degree. The acide rain pollution is related not only to the pollutant source but also the weather conditions.
