【 摘 要 】

The observation data from the CORS stations in Nanning, Wuzhou and Baise were processed with GAMIT software in this paper, and the accuracy and reliability of CORS data inversion results were verified with the help of Inverse Distance Weighted (IDW) simplified analysis process. Furthermore, the time-series variation of precipitable water vapor in the three regions under extreme weather was analyzed in a selectively manner in combination with the meteorological data from radiosonde and actual rainfall. The results showed that the PWV obtained from CORS data inversion was well consistent with that acquired from the meteorological data from radiosonde, and the overall variation trend was basically consistent with the actual rainfall before and after typhoon. Characterized by all-weather operation, high spatiotemporal resolution, and continuous monitoring of water vapor variation and etc., it could effectively supplement the shortcomings of existing upper-Air meteorological detection means, so it is of great reference value for water vapor monitoring, extreme weather warning and other aspects.
