  2. Fujita scale - Wikipedia

    en.wikipedia.org/wiki/Fujita_scale

    F5. 261–318 mph. Incredible. 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 official Fujita scale category is determined by meteorologists and engineers after a ground or ...

  3. Enhanced Fujita scale - Wikipedia

    en.wikipedia.org/wiki/Enhanced_Fujita_scale

    This includes a description word for each level of the scale. 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.

  4. Tornado - Wikipedia

    en.wikipedia.org/wiki/Tornado

    The Fujita scale, Enhanced Fujita scale (EF), and International Fujita scale rate tornadoes by damage caused. The EF scale was an update to the older Fujita scale, by expert elicitation, using engineered wind estimates and better damage descriptions. The EF scale was designed so that a tornado rated on the Fujita scale would receive the same ...

  5. Tornado intensity - Wikipedia

    en.wikipedia.org/wiki/Tornado_intensity

    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. The Fujita scale, Enhanced Fujita scale, and the International Fujita scale ...

  6. TORRO scale - Wikipedia

    en.wikipedia.org/wiki/TORRO_scale

    TORRO scale. 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.

  7. International Fujita scale - Wikipedia

    en.wikipedia.org/wiki/International_Fujita_scale

    International Fujita scale. 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 ...

  8. Tornado climatology - Wikipedia

    en.wikipedia.org/wiki/Tornado_climatology

    A tornado can be reported more than once, such as when a storm crosses a county line and reports are made from two counties. The severity of tornadoes is measured by the Enhanced Fujita Scale, which measures tornado intensity on a scale of EF0 to EF5 based on wind speed and intensity of destruction. The ratings are made after the tornado has ...

  9. List of F4, EF4, and IF4 tornadoes - Wikipedia

    en.wikipedia.org/wiki/List_of_F4,_EF4,_and_IF4...

    The Windsor–Tecumseh Tornado of 1946. F4/EF4 Tornadoes in the United States 1950–2019. This is a list of tornadoes which have been officially or unofficially labeled as F4, EF4, IF4, or an equivalent rating. These scales – the Fujita scale, the Enhanced Fujita scale, the International Fujita scale, and the TORRO tornado intensity scale ...
