The official Fujita scale category is determined by meteorologists and engineers after a ground or aerial damage survey, or both; and depending on the circumstances, ground-swirl patterns (cycloidal marks), weather radar data, witness testimonies, media reports and damage imagery, as well as photogrammetry or videogrammetry if motion picture ...
The Enhanced Fujita scale replaced the decommissioned Fujita scale that was introduced in 1971 by Ted Fujita. [6] Operational use began in the United States on February 1, 2007, followed by Canada on April 1, 2013, who uses a modified version known as the CEF-scale.
English: This is a schematic produced by Dr. Ted Fujita (1920-1998) when explaining the technical details of the Fujita tornado intensity scale when he introduced it. It was originally published in a science journal but he and his family have released all his available works for public use.
Fujita is recognized as the discoverer of downbursts and microbursts and also developed the Fujita scale, [6] which differentiates tornado intensity and links tornado damage with wind speed. Fujita's best-known contributions were in tornado research; he was often called "Mr. Tornado" by his associates and by the media. [7]
