2019年江苏省颗粒物污染气象条件分析

Meteorological condition analysis of particulate pollution of Jiangsu province in 2019

文章利用气象观测数据及大气环境观测数据,分析并与2018年相比了江苏省2019年霾的全省分布特征及主要颗粒物污染物空间分布特征。分析并与2018年相比了2019年主要影响颗粒物污染气象条件的时空分布特征。结合大气化学模式,分析总气象条件对颗粒物污染影响。由分析结果可知,2019年江苏省气象条件相比2018年略有利于颗粒物污染浓度下降,下降了3.4%,实际全省PM2.5浓度下降约6.5%,人为控制因素使颗粒物污染下降3.1%。

By utilizing meteorological observations and atmospheric environmental observations,spatial distribution characteristics of haze and particulate pollution elements of Jiangsu province in 2019 are analyzed and compared with that in 2018.And it analyzes the spatial and temporal characteristics of leading meteorological factors of particulate pollution of Jiangsu province in 2019 and compares it with that in 2018.Combined with atmospheric chemistry model,the influence of total meteorological conditions on particulate pollution is analyzed.From the analysis results,we can see that the meteorological conditions in Jiangsu Province in 2019 are slightly favorable to the decrease of particulate pollution concentration by 3.4%compared with 2018,and the actual PM2.5 concentration in the whole province is reduced by about 6.5%,and the pollution of particulate matter by artificial control factors is reduced by 3.1%.
