| 摘 要： | 为了研究区域大气污染现象及其成因,对一次区域性大气重污染过程进行了诊断分析和数值模拟研究.结果表明,在大尺度高压、低压的弱气压场控制背景下,污染物经过长时间的积累达到重污染;在锋区背景下污染物消散,区域空气质量好转.引用中尺度气象模式模拟形成区域重污染过程的有关气象要素,能较好地说明我国北部城市重污染形成的机理.

| Abstract: | To study the regional air pollution and its causes of pollution,a serious heavy air pollution process was analyzed and simulated.Results show that pollutants cumulate for a long time and form heavy pollution with the high pressure and low weak pressure in the air,and regional air quality turns good in the influence of front.A meso-scale meteorology model is used to simulate relative meteorological factors. Simulation results can explain the mechanism of heavy pollution in northern parts of China. |
