  2. Tornado intensity - Wikipedia

    en.wikipedia.org/wiki/Tornado_intensity

    Near the tornado's peak intensity, they recorded a wind speed of 115–120 meters per second (260–270 miles per hour; 410–430 kilometers per hour). Though the portable radar had the uncertainty of ±5–10 metres per second (11–22 mph; 18–36 km/h), this reading was probably within the F5 range, confirming that tornadoes were capable of ...

  3. Enhanced Fujita scale - Wikipedia

    en.wikipedia.org/wiki/Enhanced_Fujita_scale

    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.

  4. Fujita scale - Wikipedia

    Frame-home structural damage cannot exceed total destruction and debris dispersal, which constitutes F5 damage. A tornado with wind speeds greater than 319 miles per hour (513 km/h) is possible, as the 1999 Bridge Creek-Moore Tornado did have 321 mph (517 km/h) winds, but that measurement was not near ground level.

    en.wikipedia.org/wiki/Tornado

    The most extreme tornadoes can attain wind speeds of more than 480 kilometers per hour (300 mph), can be more than 3 kilometers (2 mi) in diameter, and can stay on the ground for more than 100 km (62 mi). [3] [4] [5] Various types of tornadoes include the multiple-vortex tornado, landspout, and waterspout. Waterspouts are characterized by a ...

    The 1974 Guin tornado had the highest forward speed ever recorded in a violent tornado, at 75 mph (121 km/h). The deadliest tornado in world history was the Daulatpur–Saturia tornado in Bangladesh on April 26, 1989, which killed approximately 1,300 people. [1]

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

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

    The scale ranks tornadoes from F0 to F5, with F0 being the least intense and F5 being the most intense. F4 tornadoes were estimated to have had maximum winds between 207 mph (333 km/h) and 260 mph (420 km/h). [3] [a] Following two particularly devastating tornadoes in 1997 and 1999, engineers questioned the reliability of the Fujita scale.

    New mobile radar data shows that wind speeds in the recent Greenfield tornado passed 300 mph. Scientists say it's rare.

  9. List of F5, EF5, and IF5 tornadoes - Wikipedia

    The National Weather Service in Birmingham, Alabama, noted the rating for this tornado was F4 on the Fujita scale, which has a wind speed range of 207 to 260 miles per hour (333 to 418 km/h). However, the wind speeds assigned to this tornado was between 210 and 261 miles per hour (338 and 420 km/h), indicating the potential that this tornado ...
