摘要：There was a high visibility heavy pollution event in Shenyang on October 21st, 2014. This paper analyzes the formation and maintenance of the heavy pollution weather from the aspects of weather situation, meteorological elements, atmospheric stability and pollutants transportation. The results show that the heavy pollution weather process is due to the surface layer atmosphere transports local atmospheric pollutants into the air by turbulent motion, and the inversion of the upper block pollutants diffuse into the sky, plus the northeaster wind transport, the heavy pollution occurs in Shenyang area. In the event of heavy pollution, the relative humidity is relatively low, and the moisture absorption effect of particulate matter in the atmosphere is limited, so the atmospheric visibility is not reduced to a lower level.
