| 摘 要： | 由于对流层中气象因素变化剧烈且蕴含大量的水蒸气和颗粒物，雾霾的发生也极易改变卫星信号的传播路径，从而导致对流层延迟发生变化，因此重点研究气象因素与雾霾之间的相关性问题。通过上海市2016年62 d(DOY 153～214)的大气中污染物含量资料与天顶对流层延迟比较分析发现，大气中每种污染物含量基本呈现相似的走势，天顶对流层延迟随PM2.5含量增加而增大，且在日值数据的比较中发现，上海夏季的PM2.5含量与气压、气温和相对湿度成正相关关系，与风速、降水量呈负相关关系。

| Abstract: | Meteorological factors change dramatically and contain a lot of water vapor and particulate matter, causing the propagation path of satellite signal to be prone to change, further leading to changes of tropospheric delay. Therefore, this paper focuses on the correlation between meteorological factors and haze. The atmospheric pollutant concentration data and tropospheric delay data for 62d (doy 153-214) in 2016 in Shanghai are studied. The study finds that concentrations of each pollutant in the atmosphere shows a similar trend, and the tropospheric delay values increase with increasing PM2.5 content. At the same time, the content of PM2.5 in Shanghai is positively correlated with air pressure, air temperature and relative humidity, and is negatively correlated with wind velocity and precipitation. |
