降雨监测与预报技术在防洪减灾中的应用进展
Application progress of rainfall monitoring and forecasting techniques in flood control and disaster reduction
摘要
Abstract
Flood disasters are highly sudden and develop rapidly,posing significant threats to people's lives and properties safe-ty.Rainfall is a disaster-causing factor for floods,and the accuracy of rainfall data is of great significance for flood control and disaster reduction.Focusing on rainfall monitoring and forecasting technology,we summarized the current state of rain gauge obser-vations,weather radar rainfall estimation and forecasting,numerical weather prediction,and satellite remote sensing inversion.By analyzing the application of spatiotemporal downscaling methods and multi-source data fusion technology in rainfall monitoring and forecasting,we reveal their effectiveness in improving the accuracy of both the"quantity"and"type"of rainfall data.Re-search indicates that significant progress has been made in rainfall monitoring and forecasting technology.However,challenges re-main in complex terrains,such as mountainous and urban environments,where resolution is limited and accuracy and timeliness are insufficient.Multi-source data fusion can improve the accuracy of rainfall data,spatiotemporal coverage,and prediction accu-racy.Therefore,optimizing algorithm models and integrating multi-source data from"space-sky-ground"to create high-res-olution forecasts is a future research direction.关键词
