  2. 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.

  3. TORRO scale - Wikipedia

    en.wikipedia.org/wiki/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 .

  5. Enhanced Fujita scale - Wikipedia

    en.wikipedia.org/wiki/Enhanced_Fujita_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 and Brazil.

  6. List of F4 and EF4 tornadoes (2000–2009) - Wikipedia

    en.wikipedia.org/wiki/List_of_F4_and_EF4...

    This is a list of tornadoes which have been officially labeled as F4, EF4, IF4, or an equivalent rating during the 2000s decade. 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 ...

  7. List of tornado outbreaks by outbreak intensity score

    In late 2023, American meteorologist and tornado expert Thomas P. Grazulis created the Outbreak Intensity Score (OIS) as a way to rank tornado outbreaks. [1] [2] For the score, only significant tornadoes are counted: F2/EF2 tornadoes receive 2 points each, F3/EF3 tornadoes receive 5 points each, F4/EF4 tornadoes receive 10 points each, and F5/EF5 tornadoes receive 15 points each. [1]

  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 ...

    The Fujita scale attempts to estimate the intensity of a tornado by classifying the damage caused to natural features and man-made structures in the tornado's path. A famous photo of an F4 tornado in the 1965 Palm Sunday tornado outbreak. Tornadoes are among the most violent known meteorological phenomena. Each year, more than 2,000 tornadoes ...
