摘要:

地面风速(wind speed,WS)是评估台风强度及灾害影响的重要参数,但自动气象站分布稀疏,限制了台风期地面风速场的精细监测。基于台风期大气可降水量(precipitable water vapor,PWV)与WS的相关性及风速的时间延续性,本文构建了LPWV-WS、PPWV-WS和PWV-WS3 3种地面风速估计模型。采用2019—2023年日本九州岛地区97个GNSS站的PWV数据、24个自动气象站WS观测数据及ERA5背景风场,对模型性能及应用效果进行验证。结果表明,台风期PWV与WS具有较强相关性,而非台风期相关性较弱。基于台风期样本加权的K折交叉验证结果显示,PWV-WS3模型精度和稳定性最优,其WS的平均绝对误差、均方根误差和标准差分别为0.89、1.25和1.24 m/s,转换得到的风级相应指标分别为0.44、0.71和0.70。以2023年超强台风“卡努”为例,GNSS-PWV加密后的风速场能够更清晰地反映高风速区及其随台风移动的空间演变。研究表明,GNSS-PWV可作为台风期地面风速监测的有效补充,为高时空分辨率风场重建和风灾监测提供技术途径。

Abstract:

Surface wind speed (WS) is a key indicator for evaluating typhoon intensity and assessing potential wind hazards. However, the sparse distribution of automatic weather stations limits high-resolution monitoring of surface wind fields during typhoon events. In this study, three PWV-based WS estimation models (LPWV-WS, PPWV-WS, and PWV-WS3) were developed based on the correlation between precipitable water vapor (PWV) and WS during typhoon periods, together with the temporal persistence of wind speed. The models were evaluated using PWV observations from 97 global navigation satellite system (GNSS) stations, WS observations from 24 automatic weather stations, and ERA5 wind field data collected over Kyushu, Japan, during typhoon events from 2019 to 2023. The results show that PWV is strongly correlated with WS during typhoon periods, whereas the correlation is weak during non-typhoon periods. A weighted K-fold cross-validation based on typhoon samples demonstrates that the PWV-WS3 model achieves the best accuracy and stability, with mean absolute error (MAE), root mean square error (RMSE), and standard deviation (STD) of 0.89 m/s, 1.25 m/s, and 1.24 m/s, respectively. The corresponding errors for the derived wind level (WL) are 0.44, 0.71, and 0.70, respectively. A case study of super Typhoon Khanun (2023) further demonstrates that GNSS-PWV-enhanced wind fields provide a more detailed representation of high-wind-speed regions and their spatial evolution during typhoon movement. These results indicate that GNSS-derived PWV can effectively complement conventional surface wind observations and provide a new approach for high-resolution surface wind field reconstruction and typhoon wind hazard monitoring.
