摘    要:结合2008年10月28日南京市出现的灰霾天气,利用环境空气自动监测数据、气象观测数据、卫星遥感监测秸秆焚烧信息及后向轨迹模型等资料,对灰霾天气过程及成因进行分析。结果表明,由于当晚大气扩散条件不利,周边地区秸秆焚烧产生的大量气溶胶污染物在地面东北气流的引导下向南京市城区输送,使得大气监测点颗粒物浓度异常上升,导致能见度恶化,形成了典型性重度灰霾污染天气。

关 键 词:灰霾  大气颗粒物  秸秆焚烧

Abstract:By using auto -monitored air- quality data, meteorologically observed data, telemetry information of straw burning and the backwards trajectory of pollution model, the cause and formation of the haze phenomena on 28th October 2008 in Nanjing are analyzed. Results indicate that, on the condition of the bad atmospheric diffusion and the northeastward air current, a mass of aerosol, produced by straw burning, cause a typical severe haze phenomena which includes the increasing of the particles'concentration in atmosphere and the decreasing of visibility.
Keywords:haze  particles in atmosphere  straw burning
