| 摘 要： | 以2005年1月6日辽宁中部城市群出现的区域污染事件为例,利用NCEP/NCAR全球再分析资料对2005年冬季影响我国北部的大尺度环流系统进行了客观分析,同时采用中尺度数值模式MM5对不同尺度大气边界层进行数值模拟研究.结果表明,此次污染过程中地形影响形成的气流输送汇是造成区域污染的关键原因,而较强的逆温、逆湿等典型的稳定边界层的特征则加重了局地污染.

| Abstract: | To explore the mechanism of atmospheric pollutants in Liaoning,China,in January 6,2005,the atmospheric circulation in the large-scale of North China in the winter of 2005 was analyzed by using NCEP/NCAR Reanalysis Data.Meanwhile the numerical simulation research on the different-scale of atmospheric boundary layer according to Mesoscale Model MM5 was carried out.The result showed that the main reason of this regional pollution was the airstream convergence affected by terrain,and the typical characteristics of the stabilized boundary layer of a strong temperature inversion and inverse humidity aggravated the local pollution. |
