Generally, yes.
Techincally, 100%. If it does not touch the ground it is not considered a tornado. The number of potential tornadoes that do not touch down is not known, as these weaker circulations are often difficult to detect.
It varies widley from one tornado to another, and most tornadoes will vary in strength during their time on the ground. Weak tornadoes may have peak winds of only about 65 mph. In rare cases, peak winds may exceed 300 mph. Generally weaker tornadoes are more common.
MyMy answer is that while skinny or thin tornadoes can be weaker, cuz EF-1 tornadoes are thin, OR SKINNY and while the fato huge tornadoes are really destructive and are EF-5 or EF-6 consideres like the EL RENO incident
Weaker
In a sense. Some tornadoes, usually the weaker ones, only touch down intermittently.
About 96% of tornadoes are given ratings lower than EF3.
Hurricanes usually spawn supercell tornadoes from supercells that form in their outer bands. These tornadoes are weaker on average than tornadoes from other storm systems.
Yes, generally, they are, though that does not mean that Canada does not get violent tornadoes.
Most tornadoes are produced by thunderstorms called supercells. Tornadoes spawned by other types of thunderstorm are generally weaker.
Generally, yes.
The Fujita scale does not help in predicting tornadoes, but it is a useful tool in statistical studies of tornadoes, where singling out stronger or weaker tornadoes is useful.
Based on data from the past 20 years Florida averages 66 tornadoes per year. Data from before then tends to miss many of the weaker tornadoes.
Tornadoes are strong enough to kill people, though the weaker ones usually don't kill. Usually a few dozen people die every year due to tornadoes.
No. Tornadoes need thunderstorms to form. There are little whirlwinds called dust devils, however. They look somewhat like tornadoes but are much weaker and usually harmless.
Tornadoes do form in deserts, but very rarely. Deserts often see whirlwinds called dust devils. They look like tornadoes but are weaker and form on sunny days while tornadoes form from thunderstorms.
Since official record began in 1950 through 2013, Washington has recorded 109 tornadoes. The actual number of tornadoes is likely higher, as we missed many of the weaker tornadoes early in this period.
