大气电场与大气污染物关系研究

Relationship Between Atmospheric Electric Field and Atmospheric Pollutants

为了研究大气电场与大气污染物关系,笔者利用太原地区2个气象站2012年6月—2015年5月的同步晴天大气电场、大气污染物、气象要素的观测资料,对太原地区晴天大气电场与大气污染物的相关性进行分析。结果表明:大气电场与大气颗粒物的相关性:PM10>PM2.5>PM1.0,其中PM10与大气电场的相关性比PM2.5、PM1.0显著大;大气电场与污染气体的相关性中NOx较高,其次为O3、CO,污染气体与大气基本带电粒子的相关性决定了它们与大气电场相关性的密切关系。通过对大气颗粒物的特征分析,给出了尖草坪大气电场高于桃园以及桃园大气电场在16:00左右出现1个小峰值的原因。

The paper aims to analyze the relationship between atmospheric electric field and atmospheric pollutants. With data of synchronization atmospheric electric field, atmospheric pollutants, and meteorologicalelements of two weather stations in Taiyuan from June 2012 to May 2015, the correlation of atmosphericelectric field in sunny days with atmospheric pollutants were analyzed. The results showed that： the correlationbetween atmospheric electric field and atmospheric particulate matter followed： PM10PM2.5PM1.0, and thecorrelation between PM10 and the atmospheric electric field was significantly larger than PM2.5, PM1.0; the NOx was high in the correlation of atmosphere electric field and gas pollution, followed by O3, CO; the correlationbetween pollution gases and charged particles decided the relationship between them and atmospheric electricfield. Through analysis of the characteristics of atmospheric particulate matter, the paper gave the reasons whyatmospheric electric field of Jiancaoping was higher than that of Taoyuan and atmospheric electric fieldoccurred at about 16：00 having a small peak in Taoyuan.
