FScale
Class Description
Fujita scale (referred to as EF-scale starting in 2007) for tornado damage. A set of wind estimates (not measurements) based on damage. It uses three-second gusts estimated at the point of damage based on a judgment of 8 levels of damage to 28 indicators. These estimates vary with height and exposure.
The 3 second gust is not the same wind as in standard surface observations.
Enumerations based on NOAA conventions.
