| 摘 要： | 利用2006-2010年南宫酸雨观测资料和地面资料、结合邢台探空资料及天气形势，采用数理统计方法，分析南宫酸雨变化特征及不同气象条件对酸雨的影响。结果表明：近年来南宫降水平均pH值均小于4.70，酸雨频率大于50%，属于重酸雨区或较重酸雨区。降水酸性在夏秋两季较强，而酸雨出现频率则在秋冬两季较大，降水电导率冬季最大。南宫酸雨多出现在主导风向为偏东风、静风及北-西北风|高空天气系统为切变线时，酸雨及强酸雨频率随降水量级增大而增大|酸雨强度随相对湿度和逆温增加而增强。

| Abstract: | Based on the observational data of acid rain, the ground meteorological data in Nangong from 2006 to 2010, the sounding data and synoptic situation, the characteristics of acid rain and the effect of meteorological conditions on it were analyzed. The results indicate that the mean pH value of precipitation is less than 4.70 in Nangong and acid rain frequency is more than 50%, so it belongs to the serious or more serious acid rain area. The acidity of precipitation is stronger in summer and autumn, while the frequency of acid rain is high in autumn and winter. The conductivity of precipitation is the largest in winter. Acid rain often occurs when the dominant wind is the eastward, calm and north-northwest wind. The frequencies of acid rain and serious acid rain increase with the increase of precipitation grade when upper weather system is a shear line. The intensity of acid rain increases with the increase of relative humidity and inverse temperature. |
