摘要
研究旨在对2016年12月7—12日湖南中东部地区出现的一次持续性污染天气过程进行分析,以得到本过程的空气污染物来源及造成本次污染过程的原因。笔者利用环保部门国控空气质量监测资料、常规气象资料、NCEP再分析资料、MODIS卫星遥感资料进行诊断分析,同时使用HYSPLIT-4后向轨迹模式对污染来源进行了聚类分析模拟。结果表明:连续晴好天气背景下长江中游区域生物质燃烧所造成的烟尘颗粒物排放,以及不利于污染物扩散清除的气象条件是本次持续性污染天气过程的主要原因,另外,湖南特殊的地形条件也是造成本次持续性污染天气过程的一个重要因素。该诊断分析结果得出了湖南此次复杂的大气污染过程的成因,并分析出了大气污染物的来源。
The paper aims to analyze the causes and sources of a continuous pollution weather process in the central and eastern Hunan from December 7 to 12, 2016. The air quality data from the environment departments, the meteorological observation data, the NCEP reanalysis data and MODIS satellite remote sensing data were used for diagnostic analysis, meanwhile, based on NOAA back trajectory model（HYSPLIT-4）, sources of the air pollution were analyzed. The results showed that the pollution weather process was caused by 3 main reasons： the biomass burning emissions in the middle reaches of the Yangtze River in continuing fine weather, the meteorological condition which was not conducive to dispersion and removal of pollutants,and the special terrain in Hunan.
