This list includes tornadoes rated F4/EF4/IF4 or equivalent by government meteorologists, non-government tornado experts (i.e. Thomas P. Grazulis or Ted Fujita) or meteorological research institutions (i.e. European Severe Storms Laboratory) that rated a tornado differently than the official government organization in charge of the rating ...

Without a thorough engineering analysis of tornado damage in any event, the actual wind speeds needed to cause that damage are unknown. The Enhanced F-scale was implemented in February 2007.

2025年1月10日 · Moderate tornado: 73-112 mph: The lower limit is the beginning of hurricane wind speed; peels surface off roofs; mobile homes pushed off foundations or overturned; moving autos pushed off the roads; attached garages may be destroyed. F2: Significant tornado: 113-157 mph: Considerable damage.

This is a list of tornadoes which have been officially or unofficially labeled as F4, EF4, IF4, or an equivalent rating during the 2020s decade.

The Fujita scale (F-Scale; / fuˈdʒiːtə /), or Fujita–Pearson scale (FPP scale), is a scale for rating tornado intensity, based primarily on the damage tornadoes inflict on human-built structures and vegetation.

The F4 rating was replaced by EF4 under the new Enhanced Fujita Scale. A tornado rated an F4 had winds speeds between 207 to 260 MPH. The damage from a F4 tornado is devastating, large debris become flying missles.

2012年4月10日 · Tracks of violent F4/EF-4 and F5/EF-5 tornadoes in the United States from 1950-2011. Map by Katie Wheatley. Source: SPC. I recently detailed the 58 F5/EF-5 tornadoes that have been recorded in the United States. They are the ultimate low probability, but very high consequence weather event.

2024年5月6日 · On the Fujita scale, for a tornado to be classified as an F-5, its peak wind speeds must exceed 261 mph. For a tornado to be classified as an EF-5 on the EF-Scale, the estimated three-second...

The Fujita Tornado Scale, usually referred to as the F-Scale, classifies tornadoes based on the resulting damage. This scale was developed by Dr. T. Theodore Fujita (University of Chicago) in 1971. MINIMAL DAMAGE: Some damage to chimneys, TV …

The Seymour, Texas, tornado of April 10, 1979 is a prime example of a tornado that is destined to be misjudged on the Fujita Scale. This spectacular funnel was probably capable of F4 damage, had it passed through a town.
