摘要
针对厦门市3次台风事件,利用厦门市连续运行参考站(CORS)的GNSS观测数据,使用PANDA软件进行解算,反演出大气可降水量(PWV),将获取的ERA5再分析数据与反演出的PWV数据进行对比分析,在此基础上分析厦门市受台风影响期间GNSS-PWV变化特征与实际降雨量的关系.结果表明:PWV与ERA5数据具有较好的一致性;GNSS反演PWV具有较高的精度;GNSS-PWV能够较好地反映台风期间水汽的时空动态变化过程,其与降水量之间呈现出明显的相关性.
In view of the three typhoons in Xiamen City,the GNSS observation data of Xiamen Continuous Operation Reference Station(CORS)was used for calculation with PANDA software.The obtained ERA5 reanalysis data was compared with the PWV data of the counter-performance.On this basis,the relationship between GNSS-PWV variation characteristics and actual rainfall during typhoon in Xiamen was analyzed.The results show that:PWV and ERA5 data have good consistency;GNSS inversion of PWV has high precision;GNSS-PWV can well reflect the spatio-temporal dynamic change process of water vapor during typhoons,and has a significant correlation with rainfall.
