Enhanced Fujita scale - Wikipedia
The Enhanced Fujita Scale takes into account the quality of construction and standardizes different kinds of structures. The wind speeds on the original scale were deemed by meteorologists and engineers as being too high, and engineering studies indicated that slower winds than initially estimated cause the respective degrees of damage.

Storm Prediction Center Enhanced Fujita Scale (EF Scale)
The Fujita Scale is a well known scale that uses damage caused by a tornado and relates the damage to the fastest 1/4-mile wind at the height of a damaged structure. Fujita's scale was designed to connect smoothly the Beaufort Scale (B) with the speed of sound atmospheric scale, or Mach speed (M).
The Enhanced Fujita Scale (EF Scale) - National Weather Service
The Enhanced Fujita Scale or EF Scale, which became operational on February 1, 2007, is used to assign a tornado a 'rating' based on estimated wind speeds and related damage. When tornado-related damage is surveyed, it is compared to a list of Damage Indicators (DIs) and Degrees of Damage (DoD) which help estimate better the range of wind ...
EF Scale: The Official Tornado Ranking Scale Explained
The EF-Scale is for tornadoes to rate them on a scale from 0 to 5 (and more). The EF-Scale categorized tornadoes as the Saffir-Simpson scale categorizes hurricanes. It is used for most tornadoes world-wide to assess how strong the tornado was based on a few factors.
Enhanced Fujita Tornado Damage Scale - NOAA/NWS Storm Prediction Center
Standard measurements are taken by weather stations in open exposures, using a directly measured, "one-minute mile" speed. A 95-page PDF file explaining the development and makeup of the Enhanced F-scale is available here.
Enhanced Fujita Scale - National Weather Service
The EF Scale incorporates 28 damage indicators (DIs) such as building type, structures, and trees. For each damage indicator, there are 8 degrees of damage (DOD) ranging from the beginning of visible damage to complete destruction of the damage indicator.
Recent tornado events have highlighted the need for a definitive F-scale assessment guide to assist our field personnel in conducting reliable post-storm damage assessments and determine the magnitude of extreme wind events.

Tornado Measurement and Strength: Decoding the EF Scale - AccuWeather
2024年8月8日 · Each tornado is rated from EF0 - EF5, with EF0 being the weakest and EF5 being the strongest. The EF Scale replaced the F Scale previously used. Each rating is determined by surveying the...
Enhanced Fujita Scale • The EF-scale was developed at Texas Tech Univ. involving many US interests • Has much improved wind speed / wind damage correlation with large number of damage indicators while consistent with existing US database • Adopted for use in the United States in 2007, Sills and McCarthy have been
