		The Fujita Scale is a well known scale that uses damage caused by a tornado and relates the damage to the fastest 1/4-mile wind at the height of a damaged structure.
		Fujita's scale was designed to connect smoothly the Beaufort Scale (B) with the speed of sound atmospheric scale, or Mach speed (M).
		Fujita explains explicitly that "F-scale winds are estimated from structural and/or tree damage, the estimated wind speed applies to the height of the apparent damage above the ground." Figure 1 shows graphically the relationship between the three scales.

	Fujita scale - Wikipedia, the free encyclopedia
		Fujita scale ratings are issued after a tornado has passed through an area, not while it is on the ground.
		The scale was introduced in 1971 by Tetsuya "Ted" Fujita of the University of Chicago who developed the scale together with Allen Pearson (path length and width additions in 1973), head of the National Severe Storms Forecast Center (predecessor to the Storm Prediction Center) in Kansas City, Missouri.
		The new scale was publicly unveiled at a conference by the American Meteorological Society in Atlanta on February 2, 2006.

	Fujita Tornado Damage Scale (Site not responding. Last check: 2007-10-21)
		The Fujita Scale is what looks at the amount of destruction to the environment and to man made structures that are destroyed by the tornado.
		The Pearson Scale is a more scientific way of looking at a tornado while the Fujita Scale is more subjective since it relies on the aftermath and destruction of the tornado to estimate the wind speeds of the tornado.
		This is a graph, which displays the Fujita scale shows the F-Scale along the left side of the graph as well as the level of destruction at right and the winds speeds that are capable of causing this destruction at the bottom.

		Fujita listed "F-6" and even higher ratings on on his original scale, but F-6 or higher rated tornadoes aren't thought to exist.
		The Fujita scale is different from the Saffir-Simpson scale of hurricane strength in one very important way.
		Fujita scale numbers are assigned to tornadoes only after the fact; after the National Weather Service inspects the damage.

	Fujita_Scale Forum
		The Fujita Scale (F-Scale) is a measure of tornado intensity that was invented by Dr. Ted Fujita (Fujita 1971).
		The Fujita Scale is a damage scale since numerical values are assigned based on descriptions of typical types of damage and since it has been closely aligned with photographs that depict the assigned levels of damage.
		Fujita was well aware of the criticisms leveled at the non-overlapping wind speed scales and their correlation with specific damage observations.

		The Fujita scale bridges the gap between the Beaufort Wind Speed Scale and Mach numbers (ratio of the speed of an object to the speed of sound) by connecting Beaufort Force 12 with Mach 1 in twelve steps.
		F1 on the Fujita scale is equal to B12 (73 mph) on the Beaufort scale, which is the minimum windspeed required to upgrade a tropical storm to a hurricane.
		F12 on the Fujita scale is equal to M1 (738 mph) on the Mach numbers.

	The Fujita Scale of Tornado Intensity
		The Fujita Scale is used to rate the intensity of a tornado by examining the damage caused by the tornado after it has passed over a man-made structure.
		The Fujita Scale is based on damage, not the appearance of the funnel.
		Storm spotters, storm chasers and other weather observers often try to estimate the intensity of a tornado when they are in the field, basing their judgement on the rotational speed and amount of debris being generated as well as the width.

		After testing the tornado scale for three years the TORRO Tornado Intensity Scale was announced at a meeting of the Royal Meteorological Society in 1975 and published next year in the UK (Meaden 1975-76) and in the USA (Abbey 1976).
		Having noted the existence of the Beaufort scale as being useful for speeds below hurricane speed, Dr. Fujita reflected that, in case the highest wind speeds in tornadoes might be found to approach Mach 1 (738 mph or 330 metres per second), he should allow for that when proposing his tornado damage scale.
		Moreover, because Fujita’s scale was given F numbers from F0 to F12, only the part up to F5 is of any use for all known tornadoes, rendering it very cramped in practical use.

	Fujita-Pearson Scale of Tornado Intensity
		The scale was original created in 1971 by Dr. Fujita as a way of determining the strength of tornadoes from the damage that they caused.
		Fujita and Dr. Pearson two years later published a paper that added in factors related to the width and length of the tornado path, and called the scale the Fujita-Pearson Scale.
		Yet when a spotter or anyone else from the field makes a judgment about the size of a tornado without damage data, but on the width and length of the tornado path, they are making that judgment based on the size of the tornado on the ground, which is the Pearson method.

		The Fujita Scale is named for Dr. T.
		Since, until recently, it was very difficult to actually measure wind speeds in a tornado, he devised a classification scheme based on the damage or other effects caused by the winds.
		Finally, everyone agrees that a tornado cannot really be quantified by a single number, but a scale like this at least gives you a starting point to work with.

		In the U.S., tornadoes are classified according to a system known as the Fujita or Fujita-Pearson scale, named after Professor Theodore Fujita, retired professor at the University of Chicago, and Dr. Alan Pearson, former director of the National Severe Storm Forecast Center (NSSFC), who devised the system in 1971.
		This scale may not be a perfect system for linking damage to wind speed, but it had distinct advantages over what had gone on before its inception.
		Although storm spotters, storm chasers and other weather observers often try to judge the intensity of a tornado when they are in the field, the official estimate or classification is made after the tornado has passed.

	Fujita Scale
		The Fujita Scale uses numbers from 0 through 5 and the ratings are based on the amount and type of wind damage.
		The scale had been calculated through F-12, which is Mach 1 - the speed of sound (750 mph) - but tornado wind speeds are not expected to reach these speeds; see the F-6 description below.
		If this level is ever achieved, evidence for it might only be found in some manner of ground swirl pattern, for it may never be identifiable through engineering studies.

	Fujita or F Scale for wind velocity
		In 1971, T. Fujita proposed a wind scale to cover the range from force 12 at the top of the Beaufort scale to Mach 1, the speed of sound in air, in 12 equal steps.
		The equivalent on the Fujita scale or F-scale of any wind speed M (in meters per second) can be found from the equation
		In practice, however, only whole numbers are used, and the wind velocity is estimated from effects observable in the aftermath, in which respect the Fujita scale resembles the Mercalli Scale for earthquake intensity.
