EF stands for Enhanced Fujita. It was changed from the original Fujita or "F" scale in order to provide more accurate ratings and to correct wind speeds. The original Fujita scale's damage descriptions were too generalized and it overestimated the winds of strong tornadoes.
It stands for "Enhanced Fujita" as it is a rating on the Enhanced Fujita Scale, and updated version of the Fujita scale, created by Tetsuya Fujita.
EF stands for Enhanced Fujita, which is the name of the scale. It is adapted from the Fujita scale which was developed by Dr. Tetsuya Fujita in 1971.
EF means "Enhanced Fujita" referring to the scale that is used, called the Enhanced Fujita Scale.
The F stands for Fujita as in the Fujita scale, which was invented in 1971 by Tetsuya Theodore Fujita. The Fujita scale measures the intensity of tornadoes from F0 to F5 based on damage.
It doesn't really stand for anything, apart from the F for Fujita scale. 5 is the highest on that scale for tornado intensity.
The "E" stands for Enhanced, as EF5 is a rating on the Enhanced Fujita Scale.
The E stands for Enhanced, as EF2 is a rating on the Enhanced Fujita scale.
EF5 refers to the highest rating on the Enhanced Fujita scale, which runs from 0 to 5.
The F stands for Fujita.
Enhanced Fujita
The F stands for Fujita - the name of the scale used to indicate the strength of tornadoes. The E - stands for enhanced.
The Fujita scale is a way to measure the intensity of a tornado. f5 is the most violent category. An f5 tornado has 261-318 mph winds.
