1993-2004年华东部分地区酸雨的时空分布特征及其与气象条件的关系
Distribution characteristics of acid rain from 1993 to 2004 in East China and its relation with meteorological factors
摘要
Abstract
This paper analyzes the data of 15 acid rain monitoring stations in East China from 1993 to 2004,and the results show that the acid rain disasters were serious in East China,especially in Zhejiang and Fujian province which are in south of the Yangtze River.The precipitation acidity in East China from 1993 to 2004 shows a trend of decrease then increase,while the precipitation is the most important factor affecting the conductivity and pH value.The seasonal precipitation pH value is in descending order from summer,autumn,winter,to spring,but the acid rain frequency does not change obviously with season shift.The precipitation conductivity from the 15 stations is analyzed,and the results show that the conductivity remains stable then fluctuates in big range during the 12 years,and there is a significantly positive correlation between precipitation acidity and conductivity.The monitoring and research on the composition of atmosphere and precipitation acidity should be strengthened in future meteorological work.关键词
