Abstract

Abstract: Based on monitoring data of main pollutants and the NCEP/NCAR FNL (Final Analysis) reanalysis data with resolution of 1°×1°, together with aerosol extinction coefficients data and a backward trajectory simulation method of airflow from HYSPLIT of NOAA, a serious pollution process on May 25 to 30, 2014 in Shanghai caused by sand dust and straw burning was analyzed.Pollution source, transport path, meteorological conditions and atmospheric boundary layer features during this process were discussed.The results indicate that PM_2.5 is prevailing in this process.Duration of pollution is long because of common influence of sand dust and straw burning.The horizontal transportation in the middle-low troposphere (700-850 hPa), vertical wind distribution and atmospheric stratification change provide favorable conditions for this air pollution event.Echo intensity and aerosol extinction coefficients observed by a micro pulse lidar (MPL) truly reflect the air pollution event, and both have a positive correlation with PM_2.5 concentration after they revised by squared distance of radar monitoring, which is indicative to pollution weather forecast in Shanghai.

Key words: Dust transport, Straw burning, Temperature inversion, Back trajectory, PM_2.5
