| 摘 要： | 针对2010年1-10月间重庆地区区域性灰霾整体概况初步讨论,结果表明灰霾日占观测总天数的23.03%,且多集中在大气扩散条件相对较差的第一三季度.通过对灰霾与非灰霾日典型天气渐变条件下特征因子的讨论,得到颗粒物(尤其是细粒子)对大气能见度影响显著,而黑碳对细粒子贡献显著,导致灰霾发生率增大.

| Abstract: | This article is preliminary introducing the regional overviews of haze situation in Chongqing between January to October in 2010.The result states hazes proportion is 23.03% over all monitoring days.Those hazes happen in the diffuse worse days in Spring and Autumn.It discusses those characteristic factors under the weather between the haze and the un-haze.It shows that particulates(especially fine particles)play a significant effect on the poor visibility,but also BC is the same role on fine particles.These pollutants are leading to the higher haze rate. |
