The National Weather Service's arrow showing the EF scale. This includes a description word for each level of the scale. The Enhanced Fujita scale (abbreviated as EF-Scale) is a scale that rates tornado intensity based on the severity of the damage they cause.
The 1977 Birmingham–Smithfield F5 tornado's damage was surveyed by Ted Fujita and he "toyed with the idea of rating the Smithfield tornado an F6". [13] In 2001, tornado expert Thomas P. Grazulis stated in his book F5–F6 Tornadoes; "In my opinion, if there ever was an F6 tornado caught on video, it was the Pampa, Texas tornado of 1995". [14]
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, ...

What is the difference between an EF-1 and EF-2 tornado? Tornadoes differ by wind speeds and amount of damage. On the EF Scale, an EF-2 tornado is more severe than an EF-1, with 111 to 135 mph winds.
It is often referred to as a twister, whirlwind or cyclone, [1] although the word cyclone is used in meteorology to name a weather system with a low-pressure area in the center around which, from an observer looking down toward the surface of the Earth, winds blow counterclockwise in the Northern Hemisphere and clockwise in the Southern ...
The scale is intended to be analogous to the Fujita and Enhanced Fujita scales, while being more applicable internationally by accounting for factors such as differences in building codes. In 2018, the first draft version of the IF-scale, version 0.10 was published. This version was based on a 12-step rating scale.
"In the original Twister, the idea of putting these Dorothy sensor balls into a tornado is completely science fiction, but it inspired a generation of people to want to do scientific research on ...
