The Saffir–Simpson hurricane wind scale (SSHWS) classifies hurricanes —which in the Western Hemisphere are tropical cyclones that exceed the intensities of tropical depressions and tropical storms —into five categories distinguished by the intensities of their sustained winds. This measuring system was formerly known as the Saffir ...
Tropical cyclones are defined as being warm cored, non-frontal synoptic cyclones, that develop over tropical or subtropical waters, with organized atmospheric convection and have a definite cyclonic surface wind circulation. They are classified by the wind speeds located around the circulation centre and are ranked, by the World Meteorological ...
Severe thunderstorm warning (SVR) – A severe thunderstorm is indicated by Doppler weather radar or sighted by Skywarn spotters or other persons, such as local law enforcement. A severe thunderstorm contains large damaging hail of 1 inch (2.5 cm) in diameter or larger, and/or damaging winds of 58 mph (93 km/h) or greater.
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, [ 1 ][ 2 ] with several later modifications by Köppen, notably in 1918 and 1936. [ 3 ][ 4 ] Later, German climatologist Rudolf Geiger (1894–1981 ...
The 1999 Bridge Creek–Moore tornado was a large, long-lived and exceptionally powerful F5 tornado in which the highest wind speeds ever measured globally was recorded at 321 miles per hour (517 km/h) by a Doppler on Wheels (DOW) radar. Considered the strongest tornado ever recorded to have affected the metropolitan area, the tornado ...
Tornadoes of 2014#June 3–4 – The high risk was issued at 2000Z for 60% wind probability and potential derecho; tornado probability was 10%, well short of high-risk level. Extreme hail/wind and some tornadoes were reported, although most of the activity remained along or south of the southern part of the high risk.
F5. 261–318 mph. Incredible. The Fujita scale (F-Scale; / fuˈdʒiːtə /), or Fujita–Pearson scale (FPP scale), is a scale for rating tornado intensity, based primarily on the damage tornadoes inflict on human-built structures and vegetation. The official Fujita scale category is determined by meteorologists and engineers after a ground or ...
The known Category 3 hurricanes cumulatively killed 18,361 people, including 7,469 in the 2nd half of the 19th century, 7,541 in the 20th century, and 3,351 so far in the 21st century. Four hurricanes accounted for more than half of the recorded deaths. In 1870, a hurricane killed 1,200 people in Cuba. The 1893 Sea Islands hurricane left over ...
