| 摘 要： | 利用区域中尺度大气数值预报模式(MM5)和美国国家海洋和大气局(NOAA) 后向轨迹模式(HYSPLIT-4)，对2002年10月7 —13日发生在北京及周边地区的典型大气污染过程进行了模拟与分析，揭示了该污染过程的形成机理和生消过程.结果表明:该污染过程具有区域性特征，是由本地污染源和外来污染源在特殊的气象条件下共同造成的混合型污染.HYSPLIT气流来向轨迹分析表明，北京周边地区的污染对北京有显著影响，南部周边城市污染物外源的输入是造成北京地区重污染的主要原因.

| Abstract: | The Mesoscale Model (MM5) and NOAA Back Trajectory Model (HYSPLIT-4) were used to simulate and analyze an air pollution event occurred from October 7th to 13th, 2002. The results show the formulation mechanism and development process of the event, and indicate that the pollution event was of regional characteristics and resulted from combined influences of local pollution sources and emissions out of Beijing in special weather conditions. According to back trajectory analysis based on HYSPLIT, the pollution in the surrounding areas of Beijing has significant impacts on Beijing, with the import of pollutants from the cities to the south of Beijing being the main sources. |
