摘要
摘要 由于报告方法的不一致和文献资料的普遍缺乏,建立一个全球统一的龙卷风数据库一直是一个难以实现的目标,既不利于恶劣天气气候学的研究,也不利于历史研究。以前的在线龙卷风文献也经常不一致或现已失效。许多国家或大陆通过政府赞助或独立组织来维护龙卷风信息。龙卷风档案的开发旨在利用已知龙卷风活跃地区最完整的信息来源,创建一个同类首创的全球龙卷风文献数字化综合资料库。龙卷风发生和报告的空间和时间趋势可通过交互式用户界面进行可视化,该界面采用了多种过滤方法和环境再分析数据集(如ERA5)。使用 Thomas Grazulis 的 "重要龙卷风 "引入的额外数据可能对美国龙卷风气候学研究有益。龙卷风档案 "也是一项合作性工作,数据归属清晰,扩充途径开放,创建一个通用数据模型来存储龙卷风信息将有助于数据库的维护和更新。在这项工作中,我们记录了创建龙卷风档案数据库的必要方法,对龙卷风发生的时空模式进行了更广泛的气候学分析,并概述了数据的潜在用例。我们还强调了其主要局限性,并强调了进一步实现龙卷风文献国际标准化的必要性。
The Tornado Archive: Compiling and Visualizing a Worldwide, Digitized Tornado Database
Abstract Given inconsistencies in reporting methods and general lack of documentation, the creation of a unified tornado database across the world has been an elusive target for severe weather climatology purposes and historical interest. Previous online tornado documentation has also often been inconsistent or is now defunct. Many individual countries or continents maintain tornado information through either government-sponsored or independent organizations. The Tornado Archive was developed to create a first-of-its-kind digitized synthesis of worldwide tornado documentation, using the most complete sources of information available for regions known to be tornadically active. Spatial and temporal trends in tornado occurrence and reporting can be visualized through an interactive user interface with a variety of filtering methods and environmental reanalysis datasets, such as ERA5. The additional data introduced using Thomas Grazulis’ Significant Tornadoes may be beneficial for tornado climatology studies over the United States. The Tornado Archive is also intended to be a collaborative exercise, with clear data attribution and open avenues for augmentation, and the creation of a common data model to store the tornado information will assist in maintaining and updating the database. In this work, we document the methods necessary for creating the Tornado Archive database, provide broader climatological analysis of spatiotemporal patterns in tornado occurrence, and outline potential use cases for the data. We also highlight its key limitations, and emphasize the need for further international standardization of tornado documentation.
