摘要
利用郑州大气成分站的气溶胶浓度资料和气象资料,对郑州市区PM10、PM2.5、PM1浓度的日变化和月变化特征进行了分析,并对气温、降水、风速、气压等气象要素在降水过程中与气溶胶浓度的关系进行相关分析,结果表明,气溶胶浓度与气压呈正相关,与气温、降水量、风速等气象要素呈明显负相关,且随季节变化有所差异。
The daily and monthly variation of PM10, PM2.5, PM1 concentration in Zhengzhou urban areas were analyzed with the aerosol concentration and meteorological data from Zhengzhou Atmospheric Component Station. The correlation analysis between aerosol concentration and meteorological factors in precipitation including temperature, precipitation, wind velocity, atmospheric pressure etc was carried out. The results indicate that the effect of meteorological factors on aerosol concentration is different in different season; aerosol concentration is positive correlation with atmospheric pressure, and negative correlation with temperature, the volume of precipitation and wind velocity, etc.
