摘要
结合2010年苏州市出现的一次典型灰霾天气,利用环境空气自动监测系统监测数据、气象观测数据及后向轨迹模型等资料,对灰霾天气过程及成因进行了分析。结果表明:城市灰霾现象主要诱因是大尺度环流造成局地扩散条件变差,颗粒物在近地面堆积造成的。
Combined with the typical dust--haze weather occurred in Suzhou city in 2010,the article analyzes the dust-- haze＇s forming process and causes based on the ambient air＇s automatic monitoring data,meteoro- logical observation data and backward trace model. The results sho~ that the main inducement of the weath- er is the poor local diffusion conditions caused by large--scale circulation and that leads to the accumulation of particles near the ground.
