石家庄市酸雨特征分析及其与气象要素的关系
|
摘要
该文利用1995?2015年石家庄酸雨监测数据,结合同期气象资料,用统计办法将pH值及电导率数据进行数字化整理,分析不同天气条件下(风向风速、降水、气温、湿度等)pH值及电导率的变化规律,对石家庄市区酸雨的状况和与气象要素对酸雨的影响进行综合研究。结果表明:雨量越大,降水的酸性会越强,K值会越小。酸雨频率随着风速的增大而呈递减的趋势;随着气温上升,酸雨频率明显降低;月平均相对湿度与月平均降水pH值的变化趋势相反。
In this paper, using the 1995-2015 in shijiazhuang acid rain monitoring data, combined with the same period of meteorological data, statistical method will be digital, pH and conductivity data analysis under different weather conditions(wind speed, precipitation, temperature, humidity, etc.), the change rule of p H value and conductivity of acid rain in Shijiazhuang city status and study on the effects of acid rain and meteorological elements.The results show that the greater the rainfall, precipitation acidity the stronger the will, the smaller the K value is.The frequency of acid rain and the trend of decrease with the increase of wind speed.As the temperature increases, the frequency of acid rain decreased obviously;Monthly average relative humidity in contrast to the monthly average precipitation PH change trend.
