上海地区一次典型连续颗粒物污染过程分析
Analysis of a Typical Air Pollution Event in Shanghai
摘要
Abstract
A continuous air pollution event which occurred in Shanghai during 4-9 March 2013 was inves-tigated.The main features of air pollution transportation and formation were preliminary discussed by using the hourly observation data of PM2 .5 and PM10 ,conventional weather data,data from the ground-based Micro Pulse Lidar (MPL 4B),data from FY-3A satellite and NCEP (1°×1°)reanalysis data.The results show that the pollution event was mainly influenced by the weather condition in upper and lower levels.The northwest wind after the trough,the stable stratification and the weak pressure field made air pollutants difficult to disperse.The northwest wind at 850 hPa could transport the dust to Shanghai,and then the dust subsided to the ground surface.The faint wind and the stable temperature stratification near the surface provided favorable conditions for the formation and maintenance of the heavy pollution event.关键词
