摘要: A high PM(10) episode observed at a coastal site nearby Shanghai during 18-19 January 2007 was analyzed in this study. The maximum hourly averaged concentrations for the 2 days were 0.58 and 0.62 mg/m(3), respectively. meteorological condition favorable air pollution with large-scale stagnation. There no dispersing effect by wind, scavenging function precipitation, diluting process clean marine episode. trajectories 16-19 all came from northern region kept low levels, peak time, morning of 18 to 19 January, inland areas had passed over Jiangsu province before arriving site. variation indexes (APIs) cities located upwind direction clearly shows north south. liner correlation coefficient SO(2) is 0.774 episode, while CO, it even reaches 0.995, which indicated that mainly emitted coal burning domestic heating winter. Therefore, caused transport pollutants accumulated boundary layer continental areas.
