What is the original F scale for tornadoes?

What is the original F scale?

From that, a rating (from EF0 to EF5) is assigned. The EF Scale was revised from the original Fujita Scale to reflect better examinations of tornado damage surveys so as to align wind speeds more closely with associated storm damage.

EF SCALE.

EF SCALE
EF Rating 3 Second Gust (mph)
65-85
1 86-110
2 111-135

Has there ever been an F6 tornado?

There is no such thing as an F6 tornado, even though Ted Fujita plotted out F6-level winds. The Fujita scale, as used for rating tornados, only goes up to F5. Even if a tornado had F6-level winds, near ground level, which is *very* unlikely, if not impossible, it would only be rated F5.

Has there ever been an f12 tornado?

An F12 tornado would have winds of about 740 MPH, the speed of sound. Roughly 3/4 of all tornadoes are EF0 or EF1 tornadoes and have winds that are less than 100 MPH. EF4 and EF5 tornadoes are rare but cause the majority of tornado deaths.

What is the difference between the F scale and EF scale?

The F-scale is based on the amount of destruction a tornado causes, whereas the EF-scale relies more on wind-speed to determine a tornado TMs rating.

Was the Jarrell tornado an F6?

When we talk about how powerful the tornado was, saying it was a torrent of force is an understatement. It remains as one of the most catastrophic in history, and meteorologists rated it at the top of the Fujita scale as an F5.
