| 中文摘要:卫星反演的洋面风场对全球台风灾害监测具有重要的指示意义和实用价值。利用上海市气象局3个海洋浮标站海面风场观测资料以及国内外同类卫星产品，对风云三号E星(FY-3E)的风场测量雷达(WindRAD)产品进行了精度检验，并结合2022年6月至2023年9月影响上海地区的3个台风个例进行了风场产品应用能力评估。结果表明，FY-3E/WindRAD能够较好地刻画台风的基本风圈结构特征；与浮标站实测结果相比，FY-3E/WindRAD风速反演结果基本达到业务化应用的精度要求。与国际同类风场反演结果相比，其台风风圈结构信息和最大风速信息随时间的变化规律具有较好的一致性。研究结果对FY-3E/WindRAD风场产品应用和分析具有重要的参考价值。 |

| Abstract:The satellite-derived ocean surface wind field has important indicative significance and practical value for global typhoon disaster monitoring. The wind field observation data of three ocean buoy stations of the Shanghai Meteorological Bureau and similar satellite products at home and abroad are used to test the accuracy of the wind field measurement radar (WindRAD) product of Fengyun-3E (FY-3E), and the application capability of the wind field product is evaluated in combination with three typhoons that have affected the Shanghai area during June 2022 and September 2023. The results show that FY-3E/WindRAD can better describe the basic wind circle structure characteristics of typhoons, and compared with the measured results of the buoy stations, the wind speed inversion results of FY-3E/WindRAD basically meet the accuracy requirements of operational applications. Compared with the international similar wind field inversion results, the change law of the typhoon wind circle structure information and maximum wind speed information over time has a good consistency. The research results have important reference value for the application and analysis of FY-3E/WindRAD wind field products. |
