Abstract: The paper aims to analyze the causes and sources of a continuous pollution weather process in the central and eastern Hunan from December 7 to 12, 2016. The air quality data from the environment departments, the meteorological observation data, the NCEP reanalysis data and MODIS satellite remote sensing data were used for diagnostic analysis, meanwhile, based on NOAA back trajectory model (HYSPLIT- 4), sources of the air pollution were analyzed. The results showed that the pollution weather process was caused by 3 main reasons: the biomass burning emissions in the middle reaches of the Yangtze River in continuing fine weather, the meteorological condition which was not conducive to dispersion and removal of pollutants, and the special terrain in Hunan.
