摘要
根据2007年海南省气象局4个酸雨观测站的282个观测数据,对酸雨pH值、酸雨出现频率、K值和酸雨观测降水量进行分析,并与往年的资料进行比较,分析海南省天气系统对酸雨的影响。结果表明:2007年全省酸雨出现频率为19.8%~28.9%,平均为24.5%;海口、三亚、东方和西沙的酸雨年平均pH值分别为4.96、5.62、5.22和5.30。对酸雨影响最大的是冷空气,其次是低压槽,其中以西路锋消和南海低压槽影响较为明显,副热带高压影响较小。
According to the 282 items of data available in 4 acid rain observation stations of Hainan Meteorological Bureau in 2007, the pH in rain, acid rain frequency of occurrence, conductance and acid rain based precipitation were analyzed and compared with the data in 2006 and other years. The influence of Hainan synoptic system on acid rain was analyzed. The results show that acid rain frequency in Hainan averaged 24.5% from 19.8% to 28.9% in 2007, and that mean annual pH in acid rains in Haikou, Dongfang and Xi...
