The Fujita Scale rates tornadoes from F0 to F5 based on the severity of the damage they do.
F0 is the weakest but most common category. F0 damage includes missing shingles, broken tree limbs, trees with shallow roots uprooted, gutters taken down and some trailers overturned. About 55% of tornadoes are rated F0
F1, the next lowest category, is also the second most common. F1 damage includes severely stripped house roofs, severely damaged or mostly destroyed trailers, collapse porches and roofs, and broken windows. About 25% of tornadoes are rated F1
F2 is the beginning of what care called significant tornadoes. F2 damage includes roofs torn from frame houses, trailers completely demolished, and cars lifted. large amounts of debris may start to fly. About 15% of all tornadoes are rated F2.
F3 is the third strongest and third least common category of tornado. F3 damage includes many or most of the walls in a well-built home collapsed, sometimes with just a few left standing. Most trees will be uprooted. About 4% of tornadoes are rated F3.
F4 is the beginning of what are called violent tornadoes. F4 damage consisted of well-built houses completely leveled and left as piles of rubble and trees stripped of their bark. About 1% of tornadoes are rated F4.
F5 is the strongest and rarest category on the Fujita scale classified as incredible. F5 damage consists of well-built houses being swept clean off their foundations. Sometimes houses may be carried or thrown large distances. Pavement may be peeled from roads. Less than 0.1% of tornadoes are rated F5.
A wedge tornado is a tornado that appears wider than it is tall.
No. A tornado and a twister are the same thing.
Referring to "an F3" can mean a couple different things. It may refer to one of a number of plane models including the Panavia Tornado, a fighter jet used by the RAF. It may also refer to a level on the Fujita scale, a system of rating the severity of tornadoes. On this scale the weakest tornadoes are rated F0 while the strongest are rated F5. A rating of F3 indicates a strong tornado capable of leaving well-built houses mostly destroyed.
Yes. A river, forked or not, will not affect a tornado.
There is no such thing as an E4 tornado. You most likely mean an EF4 tornado. The estimated winds for an EF4 tornado are 166-200 mph. That is equivalent to a category 5 hurricane (winds 156 mph or greater).
A tornado with estimated winds of 100 mph would be rated EF1.
The Topeka, Kansas tornado 1966 was an F5.
The Hallam, Nebraska tornado was rated F4
The intensity of a tornado is rated based on damage done on the ground.
The Waco, Texas tornado of May 11, 1953 was rated F5.
The last confirmed tornado was in Texas on September 17, 2011. It was rated EF0
The Tuscaloosa, Alabama tornado of April 27, 2011 was rated EF4.
A tornado that stays in a field would be rated EF0 as currently there is no Standford for rating tornado damage to crops.
A tornado with estimated winds of 120 mph would be rated EF2.
Tornado - 1973 is rated/received certificates of: West Germany:6 (f)
The 2013 Washington, Illinois tornado was rated as a high-end EF4.
A tornado anywhere is a violent event. If you mean by the technical definition of a violent tornado, one rated EF4 or EF5, such tornadoes do occur fairly regularly in Tornado Alley, but make up a very small minority of the tornadoes that occur there. As with most places, most of the tornadoes in Tornado Alley are rated EF0 or EF1.
