| 中文摘要:卫星反演风场对数值预报初始场的构造、台风、高空急流及水汽输送的研究等都具有非常重要的意义。利用上海市气象局3个海洋浮标站海面风场观测资料和国内外同类卫星产品,对FY-3E风场测量雷达(WindRAD)的风场产品进行了精度检验,并结合2022年6月以来影响上海地区的2个台风进行了应用能力评估。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风速反演结果基本可达到业务化应用的精度要求。与国际同类的风场反演结果相比,台风风圈结构信息和最大风速信息随时间变化的规律具有较好的一致性。本文研究结果对FY-3E/WindRAD风产品应用与分析具有重要的参考价值。 |

| Abstract:Satellite wind field inversion plays an important role in numerical forecasting, such as the construction of initial field and the research of typhoon, high-altitude jet stream and water vapor transport. The accuracy of wind field products of FY-3E Wind field measurement radar (WindRAD) was checked by using the observation data of sea surface wind field at 3 ocean buoy stations belonging to Shanghai Meteorological Bureau and similar satellite products at home and abroad, and the application capability of FY-3E WindRAD was evaluated with 2 typhoons affecting Shanghai areas since June 2022. The results showed that FY-3E/WindRAD could describe the basic wind circle structure characteristics of typhoon well, and, the wind speed inversion results of FY-3E/WindRAD could basically meet the precision requirements of business applications compared with the measured results of buoy stations. The information of typhoon circle structure and maximum wind speed obtained from FY-3E/WindRAD was in good consistent with the inversion results of similar international wind fields in time evolution. The research results of this paper have important reference value for the application and analysis of wind products of FY-3E wind field measurement radar (WindRAD). |
