The EF scale is also unofficially used in other countries, including China and Brazil. [2] [3] The rating of a tornado is determined by conducting a tornado damage survey. The scale has the same basic design as the original Fujita scale—six intensity categories from zero to five, representing increasing degrees of damage.

Under this version, each tornado would be assigned one Fujita scale rating and two Pearson scale ratings. For example, a tornado rated F4 based on damage with a path length of 63 miles (101 km) and a path width of 800 yards (730 m) would be rated F,P,P 4,4,4.

Initially receiving an official EF3 rating based on damage, the El Reno tornado was subsequently upgraded to a radar-estimated EF5 rating, the highest on the scale, based on data from a mobile radar. The University of Oklahoma 's RaXPol mobile Doppler weather radar, positioned at a nearby overpass, measured winds preliminarily analyzed as in ...
The Enhanced Fujita scale measures a tornado's intensity on a scale of 1 to 5 based on its wind speed estimates and resulting damages.
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.
The original scale is named after Dr. Ted Fujita, who developed the system to help provide a wind estimate for the amount and type of damage that a tornado can produce. In 2007, the Enhanced ...
