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.
Fujita rated tornadoes from 1916 to 1992 [4] [5] and Tom Grazulis of The Tornado Project retroactively rated all known significant tornadoes (F2–F5 or causing a fatality) in the U.S. back to 1880. [6] The Fujita scale was adopted in most areas outside of the United Kingdom. [citation needed]
The TORRO tornado intensity scale (or T-Scale) is a scale measuring tornado intensity between T0 and T11. It was proposed by Terence Meaden of the Tornado and Storm Research Organisation (TORRO) , a meteorological organisation in the United Kingdom , as an extension of the Beaufort scale .
Tornadoes can occur anywhere in the U.S., according to the National Weather Service.Tornadoes are “most common in the central plains east of the Rocky Mountains and west of the Appalachians.”
The Enhanced Fujita scale (abbreviated as EF-Scale) rates tornado intensity based on the severity of the damage they cause. It is used in some countries, including the United States and France. [1] The EF scale is also unofficially used in other countries, including China and Brazil.
The device showed a 1.54 inches of mercury (53.23 mb) pressure drop and recovery in just 1 minute, including a 0.68 of an inch of mercury (23 mb) pressure change in less than a second.
The International Fujita scale (abbreviated as IF-Scale) rates the intensity of tornadoes and other wind events based on the severity of the damage they cause. [1] It is used by the European Severe Storms Laboratory (ESSL) and various other organizations including Deutscher Wetterdienst (DWD) and State Meteorological Agency (AEMET).
