【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。
[Abstract]:In view of the current situation of frequent haze occurrence in Beijing, based on the influencing factors of haze and GPS water vapor sharing, this paper takes the specific season as the background. In this paper, the consistency between the PM2.5 content in the atmosphere and the precipitation of the tropospheric dry delay ZHDG in Beijing from January to November 2014 is analyzed. The results show that there is a good positive correlation between the PM2.5 content in the atmosphere and the precipitable water content of GPS in the summer season of the haze process, while the PM2.5 content in the atmosphere has a good positive correlation with the dry delay content in the troposphere in winter. It is found that the combination of the two changes can be used in haze weather monitoring and early warning to some extent.
