The Fujita scale and the Enhanced Fujita Scale rate tornadoes by damage caused.

The Enhanced Fujita ( EF ) Scale was an upgrade to the older Fujita scale, by expert elicitation, using engineered wind estimates and better damage descriptions.

The EF Scale was designed so that a tornado rated on the Fujita scale would receive the same numerical rating, and was implemented starting in the United States in 2007.

Significant windstorms in Clark County include the Columbus Day windstorm of October 12, 1962, and an April 6, 1972 tornado which rated F3 on the Fujita scale, striking a local school.

However, the two Hartford City tornados were rated category 1 on the Fujita scale — much less dangerous than a category 4.

The first tornado of the outbreak was also the strongest – an F4 ( see Fujita scale ) tornado that left a-long damage path through rural Culpeper and Fauquier Counties in Virginia.

The 1998 tornado was rated an F5 on the Fujita scale.

The 1998 tornado was rated an F5 on the Fujita scale.

The tornado was classified as an F4 on the Fujita scale ( now EF5 on the Enhanced Fujita scale ).

On May 2, 2012 it was announced that four players who played for the team between 2009 and 2011 would receive suspensions for their alleged participation in " Bountygate ": Saints linebacker Jonathan Vilma ( 16 games ), Saints defensive lineman Will Smith ( 4 games ), former Saints / current Browns linebacker Scott Fujita ( 3 games ), and former Saints / current Packers defensive lineman Anthony Hargrove ( 8 games ).

The cover was created by S. Neil Fujita whose design featured a large Gothic-style letter " G " with a long curl at the top emphasizing the first three letters of the title, accompanied by the hands of a puppeteer holding a set of strings over the " father " portion of the word.

Research was carried out from 2001 to 2003 ; glaciological observations were made, and both shallow cores and cores to bedrock were extracted and analyzed ( Olivier and others, 2003 ; Fujita and others, 2004 ).

The tornado was later confirmed on the same day as an EF3 on the Enhanced Fujita Scale with winds near 150 to 160 mph.

The tornado was later rated EF3 on the Enhanced Fujita Scale.

On July 6, 1893, Pomeroy was struck by a tornado that was later estimated to be F5 on the Fujita scale.

The tornado was later confirmed to be an EF-2 on the Enhanced Fujita Scale after damage assessment was completed.

Part of the Tupelo-Gainesville outbreak of April 5 – 6 in that year, the Tupelo storm, which struck at night and destroyed large residential areas on the city's north side, was subsequently rated EF5 on the modern Fujita scale.

The Pierce City tornado was an F-3 on the Fujita scale.

On May 27, 2001, Manalapan was struck by a tornado rated at F2 on the Fujita scale, causing over $ 1 million in damage.

The May 3, 1999 tornado that hit Moore was rated an F5 on the Fujita scale, and was one of the strongest and most destructive tornadoes in history.

The most powerful tornado of the 2003 South Dakota tornado outbreak was located around Centerville and was rated an F-4 on the Fujita scale.

Fujita tapped out about five seconds after the choke was applied.

Meteorologists have since retroactively categorized the Antlers tornado as an F5 on the Fujita Scale, the most powerful.

Fujita rated tornadoes from 1916 – 1992 and Tom Grazulis of The Tornado Project retroactively rated all known significant tornadoes ( F2-F5 or causing a fatality ) in the U. S. back to 1880.

Most intense tornadoes ( EF3 to EF5 on the Enhanced Fujita Scale ) develop from supercells.

La Plata has been visited by two major tornadoes in its history, both of intensity F4 on the Fujita scale.

On April 3, 1974 a tornado rated F5 on the Fujita scale cut a path directly through the middle of Xenia during the Super Outbreak, the second largest series of tornadoes in recorded history.

The Fujita scale ( F-Scale ), or Fujita-Pearson scale, is a scale for rating tornado intensity, based primarily on the damage tornadoes inflict on human-built structures and vegetation.

The Enhanced Fujita Scale was formulated due to research which suggested that the wind speeds required to inflict damage by intense tornadoes on the Fujita scale are greatly overestimated.

From these wind speed numbers, qualitative descriptions of damage were made for each category of the Fujita scale, and then these descriptions were used to classify tornadoes.

* 1971-Ted Fujita introduces the Fujita scale for rating tornadoes.

The tornado was the most intense and destructive of 5 tornadoes that touched down in Johnson County, Iowa that evening ; it was given the rank of F2 on the Fujita Scale.

WISE Center researchers contributed significantly to the development of the Enhanced Fujita Scale for rating the strength of tornadoes.

* Enhanced Fujita Scale ( EF Scale ) rates the strength of tornadoes in the US based on the observed damages

* Enhanced Fujita Scale, an improved version of the Fujita Scale used to rate tornadoes

In addition to developing the Fujita scale, Fujita was a pioneer in the development of tornado overflight and damage survey techniques, which he used to study and map the paths of the two tornadoes that hit Lubbock, Texas on May 11, 1970.
