Tornadoes develop wind the rotating updraft of a thunderstorm, called a mesocyclone, tightens into a smaller circulation. Just as a spinning ice skater speeds up when she pulls in her arms, so does the vortex of air as it narrows.
Tornadoes are sometimes divided into "weak" tornadoes "strong" and "violent" tornadoes. Weak tornadoes are those rated EF0 and EF1. Most tornadoes are weak. Strong tornadoes are those rated EF2 and EF3. Violent tornadoes are those rated EF4 and EF5. They are the rarest of tornadoes, only about 1% of tornadoes are this strong.
Less than 1% of tornadoes earn a violent rating (F4 or F5) on the Fujita Scale. The same applies the the Enhanced Fujita scale with EF4 and EF5 tornadoes.
Florida has actually had two violent F4 tornadoes in the past 60 years, but the reason such strong tornadoes are so rare has to do with the climate. Tornadoes form in very strong thunderstorms called supercells, which form best near boundaries with large contrasts in temperature and/or moisture content. In Florida, which is nearly tropical, the temperature contrasts tend to be small, and so the storms are generally not intense enough to produce strong tornadoes.
Tornadoes are considered the most violent of all winds, with wind speeds that can exceed 300 miles per hour. These fast-moving columns of air can cause significant damage and destruction in their path.
Most tornadoes are considered weak, with wind speeds less than 110 mph. Strong tornadoes, with wind speeds between 111-135 mph, are less common, while violent tornadoes, with wind speeds over 136 mph, are the rarest and most destructive.
The year with the most violent tornadoes on record was 1974, with a total of 36 tornadoes rated as violent.
Most violent tornadoes (F4 and F5) occur in the months of March-June.
The most violent tornadoes generally occur in North America.
All tornadoes are considered a violent weather events in general terms. However, less than 1% of tornadoes attain a violent rating of EF4 or EF5 on the Enhanced Fujita scale.
No, about 1% percent of tornadoes are rated as violent EF4 or EF5). About 75-80% of tornadoes are rated as weak (EF0 or EF1).
No, tornadoes are not calm. They are violent, rotating columns of air that can cause significant destruction and are characterized by strong winds and intense atmospheric instability.
No. Tornadoes are violent whirlwinds that can form during thunderstorms.
A tornado is a violent weather event the most violent in fact. Tornadoes are produce by thunderstorms and are, in simple terms, extremely violent rotating windstorms.
Tornadoes
Violent tornadoes have been recorded in most states east of the Rockies. However, most of the violent tornadoes occur on the Great Plains in the central part of the country.
Tornadoes are sometimes divided into "weak" tornadoes "strong" and "violent" tornadoes. Weak tornadoes are those rated EF0 and EF1. Most tornadoes are weak. Strong tornadoes are those rated EF2 and EF3. Violent tornadoes are those rated EF4 and EF5. They are the rarest of tornadoes, only about 1% of tornadoes are this strong.
No. Tornadoes are violent whirlwinds. The strongest of tornadoes produce damage comparable in severity to that of an atomic bomb.
