摘    要:利用北京空气质量监测资料和NCEP再分析资料,分析了北京发生PM10重污染的天气形势。研究表明:1)虽然北京地区PM10重污染(API指数3级以上)每年只有10 d左右,但与之关联的轻微或轻度空气污染(API指数3级)天数,却可能占全年3级污染总天数的40%-50%。因此,分析研究造成北京PM10重污染的天气形势,对于空气污染的预警预报以及污染源的控制和管理,都具有十分重要意义。2)通过海平面气压场的主观分析,确定了二类北京PM10重污染的典型天气形势,即高压南下东移阻滞型和与北上台风(或热带低压)相关联的弱高压控制型,并指出了后者在2008年奥运会期间,对开展北京空气污染预报和污染控制的指导作用。

关 键 词:PM10重污染  天气形势  北京

Abstract:PM10 heavy air pollution events(API great than 3 grades) in Beijing area have been researched by analyzing air quality data and NCEP reanalysis data.1)The days of PM10 heavy air pollution in Beijing area are only about 10 days,but air pollution days related with them maybe accounted about 40%~50% of total air pollution days in Beijing.So,the study on synoptic pattern resulting in PM10 heavy air pollution is very important for the forecast and project of PM10 heavy air pollution and the control and management of air pollution sources.2)By using objective analytical method of surface air pressure,two typical types of synoptic patterns,which often result in PM10 heavy air pollution in Beijing area and around,was defined,that are the blocking pattern of moving southward anticyclone and the weak anticyclone pattern related to moving northward tropical cyclone.
Keywords:PM10 heavy air pollution  synoptic pattern  Beijing
