First, it's the Fujita Scale, not fajita.
These wind speeds are only estimates that are based on damage and were later found to be inaccurate.
F0: 40-72 mph
F1: 73-112 mph
F2: 113-157 mph
F3: 158-206 mph
F4: 207-260 mph
F5: 261-318 mph.
The strongest tornado in the Fujita scale is F5.
Estimated wind speeds for an F1 tornado on the original Fujita Scale are 73-112 mph. These were found to be inaccurate, though, and were adjusted to 86-110 mph for an EF1 tornado.
That would be the Fujita scale or, more recently, the Enhanced Fujita scale. However, both scales base rating primarily on damage, with the wind speeds only being estimated based on that damage.
in the regular fujita scale f5 tornado maximum wind speeds are 261 - 318 but on the enhanced fujita scale its over 200+mph for an EF5
It is named for its creators: civil engineer Herbert Saffir and meteorologist Robert Simpson. Saffir was the one who first came up with the wind scale and presented it to Simpson, then head of the National Hurricane Center, who made made additions to the scale to account for storm surge and flooding.
the Fujita scale (not the fajita scale) is used to tell how powerful a tornado is.
F5. And its the Fujita scale, not fajita.
The scale is based on wind speeds in the hurricane
They use the Beaufort scale to classify winds and wind speeds.
The strongest tornado in the Fujita scale is F5.
The Beaufort scale is a measure that relates wind speed to observed conditions at sea or on land. Its full name is the Beaufort Wind Force Scale, although it is a measure of wind speed and not of "force" in the scientific sense of the word.
Dr. Tetsuya Theodore Fujita
The Beaufort wind force scale, or simply Beaufort scale, was devised at the beginning of the 19th century (around 1805) to provide a standard measure of wind speeds for sailors.
I believe you mean the Fujita scale. This is a scale, developed in 1971 used to rate the intensity of tornadoes based on damage and to provide wind speed estimates. It ranges from F0 at the weakest to F5 at the strongest. In 2007 it was replaced in the U.S. by the Enhanced Fujita (EF) scale, which provides more detailed damaged descriptions and corrected wind speed estimates.
There are several "scales" used for describing wind speed, but the most common may be the Beaufort Scale of wind speeds, in 12 steps from "Calm" to "Light Air", all the way to "hurricane". The Beaufort Scale isn't used to MEASURE wind speed, but to DESCRIBE it.
Estimated wind speeds for an F1 tornado on the original Fujita Scale are 73-112 mph. These were found to be inaccurate, though, and were adjusted to 86-110 mph for an EF1 tornado.
The is no Fajita scale. The Fujita scale provides basic standards by which to assess the damage done by a tornado. Based on the severity of the damage a tornado is assigned a rating, which can range from F0 for the weakest tornadoes to F5 for the strongest.
