Abstract This paper analyzes the ash haze process in Fenghua during the 12th,1st and 2nd 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 14th Dec,2015 to 16th 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.
