摘要：

In order to investigate the effect of meteorological factors on PM2.5 in Beijing, the continuous observation data which from July to September of 2006-2008 of Baolian and Shangdianzi stations are used to analyze. The result showed that: the transportation of southerly wind aggravated the fine particulate pollution degree of urban, and it is also the primary reason of the pollution in rural area. PM2.5 concentration decreased as the northerly wind increased in both urban and rural areas. This indicates that the northerly wind is relatively clear, can dilute and disperses the pollutants in the Beijing area, but the southerly wind play the opposite role. Hourly precipitation above 1 mm can eliminate PM2.5 effetely. (c) 2011 Published by Elsevier Ltd.
