摘要
文章利用颗粒物激光雷达、空气污染物监测仪器及能见度仪等数据资料对奉化冬季12、1、2月的灰霾过程进行分析,选取2015-12-14～2015-12-16的1个典型灰霾发生个例,结合地面气象要素,分析了灰霾发生过程中相对湿度、能见度以及风速数据的变化,进而分析出灰霾发生的原因。同时利用颗粒物激光雷达数据对灰霾的时空分布特征进行解析,了解灰霾发展消散期间气溶胶在时间和空间上的分布特征,进一步了解灰霾的光学特性。
This paper analyzes the ash haze process in Fenghua during the 12 th,1 st and 2 nd months of winter based on the data from atmospheric particle lidar,air pollutant monitoring instrument and visibility meter.A typical case of ash haze happening from 14 th Dec,2015 to 16 th Dec,2015 is selected to analyze changes in relative humidity,visibility and wind speed data during the ash occurrence process combing with ground meteorological elements.Then,the causes for the ash haze are analyzed.Meanwhile,by using the data of atmospheric particle lidar,the spatial and temporal distribution characteristics of the ash haze are analyzed.The distribution characteristics of the aerosols in time and space during the ash haze development and dissipation have been known,which would further understand the optical properties of ash haze.
