中国龙卷灾情调查研究进展

A review of tornado damage survey research in China

  • 摘要: 龙卷灾情调查是获取龙卷地面风场特征、评估灾害强度及构建高质量龙卷个例库的基础性工作,对提升龙卷监测预警能力具有重要意义。从龙卷地面风场特征、强度定级标准、调查技术方法、龙卷个例库建设及业务流程五个方面,梳理了2015年以来我国龙卷灾情调查的主要研究进展。在此基础上,剖析了当前调查工作面临的关键瓶颈,包括调查流程普及不足、关键要素数据采集不完整、强度评定地区差异显著等。针对上述问题,从完善灾情调查技术体系、强化现场调查人员和气象信息员队伍培训、建立标准龙卷个例库及推动强度评估标准本地化应用等方面提出对策建议,以期为龙卷灾情调查制度的完善和龙卷个例库的持续优化提供参考依据。

     

    Abstract: Tornado damage surveys are fundamental to characterizing near-surface wind fields, assessing disaster intensity, and establishing high-quality tornado database. They play a critical role in enhancing tornado monitoring and warning capabilities. This article reviews the main advances in tornado damage surveys in China since 2015 from five perspectives: near-surface wind field characteristics, intensity rating criteria, survey methodologies, tornado database construction, and operational workflows. Based on this review, we identify the key bottlenecks currently facing the damage survey, including limited standardization and dissemination of the survey process, incomplete data collection of key elements, and significant regional differences in intensity evaluation. To address these challenges, We propose several countermeasures and recommendations, including improving the technical system of damage survey, strengthening the training of damage investigators and meteorological information personnel, establishing a standard tornado database and promoting the localization application of tornado intensity evaluation standards. These efforts are expected to provide a reference for improving the tornado damage survey system and tornado database in China.
