The highest wind speed ever measured in a tornado, which is also the highest wind speed ever recorded on the planet, is 301 ± 20 mph (484 ± 32 km/h) in the F5 Bridge Creek-Moore, Oklahoma, tornado which killed 36 people. [119] The reading was taken about 100 feet (30 m) above the ground. [3]
The old scale lists an F5 tornado as wind speeds of 261–318 mph (420–512 km/h), while the new scale lists an EF5 as a tornado with winds above 200 mph (322 km/h), found to be sufficient to cause the damage previously ascribed to the F5 range of wind speeds.
Tornado intensity is the measure of wind speeds and potential risk produced by a tornado. Intensity can be measured by in situ or remote sensing measurements, but since these are impractical for wide-scale use, intensity is usually inferred by proxies , such as damage.
A tornado is seen West of Dodge City, Kansas moving North on May 24, 2016 in Dodge City, Kansas.
The rating of any given tornado is of the most severe damage to any well-built frame home or comparable level of damage from engineering analysis of other damage. Since the Fujita scale is based on the severity of damage resulting from high winds, a tornado exceeding F5 is an immeasurable theoretical construct.
Most UK tornadoes are T6 or below with the strongest known UK tornado estimated as a T8 (the London tornado of 1091). For comparison, the strongest detected winds in a United States tornado (during the 1999 Oklahoma tornado outbreak) would be T11 using the following formulas: v = 2.365 (T+4) 3/2 m/s v = 8.511 (T+4) 3/2 km/h v = 5.289 (T+4) 3/2 mph
While tornadoes can flatten homes and level trees, so too can microbursts, which are storms that can tear through an area with 100 mph winds. An EF-3 tornado caused widespread destruction in the ...
These scales – the Fujita scale, the Enhanced Fujita scale, the International Fujita scale, and the TORRO tornado intensity scale – attempt to estimate the intensity of a tornado by classifying the damage caused to natural features and man-made structures in the tornado's path. Tornadoes are among the most violent known meteorological ...
