【摘要】：針對北京地區(qū)霧霾頻發(fā)的現(xiàn)狀,該文基于霧霾與GPS水汽共有的影響因素,以具體季節(jié)為背景,對北京地區(qū)2014年1—11月對流層干延遲ZHD、GPS可降水量與大氣中PM2.5含量的一致性做了分析。研究結(jié)果表明:霧霾過程中盛夏季節(jié)表現(xiàn)為大氣中PM2.5含量與GPS可降水量具有很好的正相關(guān)性,而在冬季則表現(xiàn)為大氣中的PM2.5含量與對流層干延遲含量具有很好的正相關(guān)性,并發(fā)現(xiàn)結(jié)合兩者的變化在一定程度上可用于霧霾天氣的監(jiān)測與預(yù)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.
