摘要
利用云南省10个环境影响评价个例及2019年昆明市臭氧监测资料中发生轻度污染的8个个例,分析研究了逆温的强度特征与大气污染的关系,逆温强度对常规大气污染物浓度有较好的正相关,逆温强度越大,大气污染物浓度越大。分析表明逆温强度大于等于1.2℃/100 m的逆温才会对常规大气污染物传输和分布产生影响,对常规大气污染物传输和分布产生影响的逆温统计频率与常规统计的逆温频率相差较大。臭氧污染浓度与同期逆温相关性较差,逆温不是影响臭氧生成、传输和分布的主要气象因素。
Based on 10 environmental impact assessment cases in Yunnan Province and 8 slightly-polluted casesin monitoring data of ozone in Kunming in 2019,the relationship between inversion intensity and air pollution is analyzed.Inversion intensity has a good positive correlation with the concentration of conventional air pollutants.The higher the inversion intensity,the higher the concentration of air pollutants.This statistical example shows that the inversion intensity of 1.2℃/100 m or more will have an impact on the transmission and distribution of conventional air pollutants,and the inversion statistical frequency that has an impact on the transmission and distribution of conventional air pollutants is quite different from that of conventional statistics.The correlation between ozone pollution concentration and inversion is poor,and inversion is not the main meteorological factor affecting ozone generation,transmission and distribution.
