| 摘 要： | 利用辽宁中部地区2008年1月的气象与环境监测资料,对该地区发生的一次灰霾天气过程进行了分析。结果表明,由于冬季地面、高空稳定的天气条件,特别是地面500m以下的城市边界层区域的大气扩散能力的较弱,造成了空气中污染物不能扩散,导致环境空气质量恶化,颗粒物浓度增高,能见度下降,形成灰霾过程。

| Abstract: | Based on meteorology and environment monitoring data in Jan.2008 in Liaoning central region,a typical haze weather process was analyzed.The results showed that the haze was formed due to structure of surface and upper air layer in Liaoning central region,especially for atmospheric dispersion weak ability in lower air layer under 500m called urban boundary layer.It made air quality and visibility declined and particulate matter concentration increased. |
