摘　　要：利用2004年9～11月在番禺区气象局采集到的气溶胶质量浓度资料和同期的气象资料，分析了番禺秋季气溶胶质量浓度变化及其与气象条件的关系。结果发现：番禺秋季大气污染物主要是PM10，PM10中以细粒子（PM2.5）为主，而且污染严重；气溶胶污染严重时大气层结稳定，污染高值主要出现在西北气流和东北气流的共同影响下，受周边环境的影响明显；PM（PM10和PM2.5）浓度超标日的天气过程主要出现在台风外围环流云系的影响下；气溶胶对能见度的影响较大，二者负相关明显。By utilizing the aerosol sample and meteorological data collected from September to November in 2004 at Panyu District Bureau of Meteorology, the relations between aerosol concentration change and meteorological conditions were analyzed . The results show that PM10 was the main air pollutant in autumn of Panyu, and fine particle dominated in PM10. Atmosphere is stable when aerosol pollution is serious, with high concentration occurring under northwest/northeast airflow and influenced by surroundings dramatically ; the peripheral downdraft of typhoon often brings about severe pollution weather; aerosol has significant negative correlation with the visibility.
