Committee Members Sought for NEW ASCE/SEI Standard for Estimating Wind Speeds in Tornadoes and Other Windstorms

June 26, 2014

ASCE is seeking members to serve on a committee for the development of a national consensus standard on estimating wind speeds in tornadoes and other windstorms. The intent of the standard is to develop standardized methods for estimating the intensity of tornadoes and other severe wind storms.

Users of the standard could include, but are not limited to, wind and structural and forensic engineers, meteorologists, climatologists, forest biologists, risk analysts, emergency managers, building and infrastructure designers, and the media.

The content of the standard would include improvements to the existing damage-based Enhanced Fujita (EF) scale to address known problems and limitations, and incorporation of additional methods to estimate intensity such as those based on radar measurements, treefall pattern analysis, and forensic engineering analysis, and archival of the data used for estimating wind speeds.

Interested parties may submit an online standards committee application to apply for participation. For more information, please contact James Neckel, Codes and Standards Coordinator, at
