摘　　要：针对北京地区雾霾频发的现状,该文基于雾霾与GPS水汽共有的影响因素,以具体季节为背景,对北京地区2014年1—11月对流层干延迟ZHD、GPS可降水量与大气中PM2.5含量的一致性做了分析。研究结果表明:雾霾过程中盛夏季节表现为大气中PM2.5含量与GPS可降水量具有很好的正相关性,而在冬季则表现为大气中的PM2.5含量与对流层干延迟含量具有很好的正相关性,并发现结合两者的变化在一定程度上可用于雾霾天气的监测与预警。Haze is combination of tiny particles suspending in the atmosphere and complex meteorological conditions,the GPS zenith hydrostatic delay（ZHD）and GPS perceptible water vapor（PWV）are also influenced by it.Based on the mutual influence of these two factors,this paper studied the influence of ZHD,GPS PWV on haze in Beijing area from January to November,2014.The results showed that the content of PM2.5in the atmosphere,ZHD and PWV had a good consistency in haze weather,also found that the combination of both could forecast the haze weather.
