Abstract In order to improve the level of meteorological services,a comprehensive analysis was conducted on the meteorological data and PM2.5 concentration data of heavy haze weather in the Tongliao area from November 6th,2017 to November 7th,2017.The results show that during this haze process,there was no obvious cold air in the high altitude,and the ground was a weak atmospheric pressure field.The atmospheric structure was stable,the wind speed was low,the inversion frequency was high,and the intensity was high.At the same time,the increase in pollutant emissions,the obstruction of the Greater Khingan Mountains,and the extinction effect of high concentrations of PM2.5 have caused the occurrence of this severe haze weather process.The research results provide support for improving the prevention ability of haze weather in Tongliao City.
