1961-2012年江苏省霾日时空变化特征及影响因素分析
Spatial and temporal variations of haze day and its influencing factors from 1961 to 2012 in Jiangsu province
摘要
Abstract
Based on the observed meteorological data from 69 weather stations during 1961-2012 in Jiangsu prov-ince and atmospheric aerosol data of 2012 in Suzhou,haze days were identified and selected and then their tempo-ral and spatial characteristics and relationship with meteorological factors and pollutants were analyzed.The results show that the number of annual haze days in all stations is in an increasing trend from 1961 to 2012,and this trend is significant for 85% stations.Mean annual haze day in Jiangsu province is a significant upward trend,especially during 201 1-2012.The difference in spatial distribution of haze days is not obvious before 1980,while since 1980, the haze days have occurred mainly in the south of Jiangsu province and seldom in the eastern coastal area.Haze often happens in winter and spring,especially in December and January.Less precipitation and low wind speed are favorable to occurrence of haze weather.Except sulfur dioxide,concentrations of PM10 ,PM2.5 ,nitrogen dioxide and other pollutants increase with the increase of haze levels.Among them,PM2.5 concentration increases significantly.关键词
