ANALYSIS OF TRANSMISSION CHARACTERISTICS AND POTENTIAL SOURCES OF AIR POLLUTANTS IN JIAYUGUAN

  • 摘要: 利用Meteoinfo软件中的Trajstat插件对2019-03—2020-02期间抵达嘉峪关市的气团进行后向轨迹模拟,并结合各类大气污染物数据,对嘉峪关市四季的后向轨迹进行聚类分析,研究抵达嘉峪关市的主要气团输送路径及对应路径的污染物浓度特征。通过潜在源贡献因子法(PSCF)及权重浓度轨迹分析法(CWT)来分析PM10与O3的输送来源及主要潜在源区。结果表明:输送至嘉峪关市的气团中,西北方向气团轨迹数目和污染轨迹数目占比均大于其余方向,嘉峪关市四季的大气污染更易受到西北方向气团的影响。嘉峪关市春季PM10污染相对严重,更易受到新疆东部地区潜在源区的影响,其余三季PM10污染相对较轻,潜在源区主要集中在新疆东部地区,少数位于嘉峪关市东北方向。嘉峪关市春、夏季的O3污染相对严重,强潜在源区主要集中在新疆东部地区及甘肃河西走廊地区,秋、冬季O3污染相对较轻,其中秋季潜在源区主要位于甘肃河西走廊地区,冬季潜在源区主要位于新疆东部地区。
