A scale of tornado severity with numbers from 0 to 6, based on the degree of observed damage.
- ‘Rated at F2 on the Fujita scale, the storm would have inflicted great damage had it passed through a major town.’
- ‘The Fujita scale measures damage with ratings, with the strongest being F - 5.’
- ‘Reports had it pegged as an F4 tornado on the Fujita scale, topping out with wind speeds in excess of two hundred forty miles per hour.’
- ‘As with the Saffir-Simpson and the Fujita scales, the new snowstorm rating system will have five levels.’
- ‘Tornadoes are measured by the Fujita scale, and this is shown as an F1 to F5 tornado.’
Mid 20th century: named after Dr. Tetsuya Theodore Fujita (1920–1988), the meteorologist who chiefly devised it.
