Process Analysis about the Impact of a Strong Cold Front on Air Pollution Transportation in Eastern China in Spring

  • 摘要: 利用CMAQ(4.7.1)和HYSPLIT后向轨迹模式,结合长岛和洪泽湖站点污染物观测数据,对2011年3月31日—4月3日影响我国东北部地区的一次典型强冷锋天气空气污染过程进行模拟分析,验证表明模式能较好地模拟此次强冷锋过程. 由结果可知,此次强冷锋前后污染物浓度呈先升后降又上升的现象. 在冷锋移动过程中,锋前出现一条高浓度污染带,锋面将污染物抬升至800~500 hPa的高度,使污染物在对流层中层快速向西太平洋传输;冷锋对当地污染物的去除不仅有水平方向的推动作用,还会使污染物向高空输送. 锋面过后污染物浓度急剧降低,冷锋对长岛站点SO2、O3、NOx、PM2.5的清除率分别为90.87%、34.10%、50.56%、72.69%,对洪泽湖站点则分别为82.53%、50.45%、65.11%、36.80%. 锋面过去1~2 d后,高压控制天气形势下污染物再次开始积累、浓度回升. 冷锋前后污染物形成一个“积累—锋前抬升—高空平流输送—锋后大风清除—积累”的循环.
