摘要: 本研究利用一个多尺度空气质量模式系统,模拟了2002年9月3~9日间山西省排放的大气颗粒物向北京地区的输送过程,以分析下垫面非均匀性和天气条件对输送过程的影响以及源于山西污染物对北京地区颗粒物浓度的贡献。分析结果显示:山西省排放的污染物能够被输送到北京地区,具有明显的输送通道,而且不同地区排放的污染物的输送路径是不相同的。山西排放的PM10对北京地区近地面PM10浓度的影响可达10~30μg/m3,500m高度的影响高达30~70μg/m3。

Abstract: In this study transport processes of airborne particulates originated from Shanxi to the Beijing region during the period of 3 to 9 September 2002 are investigated by use of the Community Multi-scale Air Quality (CMAQ) modeling system with the meteorological fields simulated by the Regional Atmospheric Modeling System (RAMS). The influences of the complex terrain and the weather conditions on the transport processes as well as contribution of the pollutants from Shanxi to the particulate concentrations over Beijing are discussed. The results indicate that the pollutants emitted in Shanxi can be transported to Beijing along certain pathways, and these pathways are quite different due to the difference in source locations in Shanxi. Contributions of the Shanxi sources to the PM10 concentrations over Beijing are up to 10~30μg/m3 in the surface layer while up to 30~70μg/m3 at a height of 500m.

Key words: airborne particulates, air quality, CMAQ
