Windstorms in the U.S.

Windstorms in the U.S. This feature layer, utilizing data from the National Oceanic and Atmospheric Administration (NOAA), displays windstorm paths in the United States between 1955 and 2025. Per NOAA, “Damaging winds are often called “straight-line” winds to differentiate the damage they cause from tornado damage. Strong thunderstorm winds can come from a number of different processes. Most thunderstorm winds that cause damage at the ground are a result of outflow generated by a thunderstorm downdraft. Damaging winds are classified as those exceeding 50-60 mph.” Windstorms in and around Washington D.C. Data currency: 2025 Data source: Storm Prediction Center Data modifications: Added field "Date_Calc" For more information: Severe Weather 101: Damaging Winds; NSSL Research: Damaging Winds Support documentation: SPC Tornado, Hail, and Wind Database Format Specification For feedback, please contact: [e-mail] National Oceanic and Atmospheric Administration Per NOAA, its mission is "To understand and predict changes in climate, weather, ocean, and coasts, to share that knowledge and information with others, and to conserve and manage coastal and marine ecosystems and resources."美国暴风灾害数据集。本要素图层采用美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）的公开数据，展示了1955年至2025年间美国境内的暴风移动路径。根据NOAA的官方定义：“具有破坏性的大风常被称为‘直线风’，以区分其与龙卷风造成的破坏类型。强雷暴大风可由多种不同过程诱发。绝大多数在地面造成破坏的雷暴大风，均源于雷暴下沉气流产生的外流。破坏性大风的分级标准为风速超过50-60英里每小时。”本数据集涵盖华盛顿特区及其周边区域的暴风灾害情况。数据更新至2025年，数据源为风暴预测中心（Storm Prediction Center）。数据修改项：新增“Date_Calc”字段。更多相关参考资料包括：《恶劣天气101：破坏性大风》、美国国家强风暴实验室（National Severe Storms Laboratory, NSSL）发布的《破坏性大风》研究内容。配套支持文档：《风暴预测中心龙卷风、冰雹与大风数据库格式规范》。如需反馈，请联系：[e-mail]。美国国家海洋和大气管理局（NOAA）的官方使命为：“深入理解并预测气候、天气、海洋与海岸带的变化，向公众分享相关知识与信息，并保护和管理海岸与海洋生态系统及资源。”
