摘　　要： 分析了深圳地区2003～2004年发生的6个典型污染过程.基于WRF中尺度气象模式的分析表明深圳地区的空气污染过程主要受副热带高压、热带气旋及变性冷高压脊的影响.HYSPLIT气流轨迹分析说明珠江三角洲上游地区的污染对深圳地区存在影响,当深圳处于海上气团控制时,空气质量较好. The six typical air pollution processes occurred in 2003-2004 years were analyzed in Shenzhen area. The analyses based on the WRF mesoscale meteorological model showed that air pollution processes were controlled by weather systems such as subtropical high, tropical cyclone and degraded cold high pressure system. The analyses based on the HYSPLIT trajectory model indicated that pollutants from the upstream regions of Pear River Delta could influence the Shenzhen area, there would be better air quality when Shenzhen area was controlled by air mass from ocean.
