厦门市"米克拉"台风事件GNSS PWV反演以及与降雨量相关性分析
GNSS PWV Retrieval and Correlation Analysis with Rainfall During Typhoon Mikla in Xiamen City
摘要
Abstract
In this paper,the atmospheric precipitation water vapor(PWV)is retrieved by using the GNSS continu-ous operation reference station(CORS)data during Typhoon Mikla in Xiamen in 2020 and the PWV is evaluated by taking the PWV from ERA5 reanalysis data as a reference.The relationship between GNSS PWV variation char-acteristics and actual rainfall during the typhoon is then analyzed.The results show that the average PWV bias be-tween GNSS PWV and ERA5 PWV is about 0.72 mm with the correlation coefficient reaching about 0.90,illustra-ting the high accuracy and high consistency of the GNSS PWV.GNSS PWV can reflect the spatial-temporal dynam-ic change process of water vapor during the typhoon period and is consistent with the typhoon rainfall process.关键词
