That is not fully understood and is the topic of ongoing research by scientists. What is known is that tornadoes are violently rotating vorticies of air that form during some thunderstorms. Wind air in and near a tornado spiral inward and upward at very high speeds around a center of intense low pressure.

Most tornadoes form from the mesocyclone, or rotating updraft, of a powerful type of thunderstorm called a supercell. The bottom portion of the mesocyclone tightens and intensifies to produce the tornado, but it is not known how this happens or why happens in some storms and not others.

its about tornadoes and how they work/do.


Tornadoes are not named. Tornadoes are too short-lived for a name to be useful, and there are simply too many of them for any naming system to work.


The United States averages about 1200 tornadoes per year, which would work out to about 3600 tornadoes in an average 3-year period.


Tornadoes hurt and kill people and can destroy their homes, schools, and places where they work.


No. While tornadoes are usually accompanied by lightning and can sometimes produce static discharges, electricity has nothing to do with the way they work.


People research tornadoes to learn more about them and how they work. Partially out of curiousity and partially to get information that could improve warnings.


There are to primary ways. First they will chase tornadoes and scan them with radar or, more rarely, try to get probes inside them. It is difficult and dangerous work. Second, scientists will try to model tornadoes in supercomputers.


In the dynamics of how they work, no. Ceiling fans are powered by electric motors. Tornadoes are driven by thermodynamic processes whether they are in the northern or southern hemisphere. In terms of direction, yes. Most ceiling fans spin clockwise as to most tornadoes in the southern hemisphere.


The number of tornadoes in 1900 is not known. Official records for the United States only go back to 1950, and the vast majority of tornadoes were missed. Work by tornado expert Thomas P. Grazulis indicates that there were at least 51 significant tornadoes (F2 or stronger or causing a death) in the U.S. in 1900. However, most tornadoes are not rated as significant, and many F2 tornadoes may still have been missed.


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.


Tornadoes in the U.S. are called tornadoes.


That is difficult to determine. Records of F1 tornadoes before the 1980s are unreliable as many tornadoes that would likely be rated F1 were missed. The only extensive published work from before 1950 only lists F1 tornadoes if they result in a fatality, and killer F1's are rare.Since 1950 Florida has recorded 846 F1 tornadoes.


The idea is that studying tornadoes, which sometimes means getting close to them, allows us to better understand them. A better understanding of tornadoes may help us predict them, which would mean better warnings for people who might be in the path of a tornado.


It depends on what you mean by extreme. Tornadoes of EF4 and EF5 tornadoes, however are often referred to as violent tornadoes. These account for about 1% of all tornadoes.


Tornadoes don't get named, Hurricanes do, but Tornadoes don't.


Thin tornadoes are often called rope tornadoes.


Most tornadoes are supercell tornadoes.


The first person to have conducted extensive research on tornadoes was John Park Finely, whose main work, beginning in 1879, essentially started the study of tornado climatology.


No. Tornadoes are violent.


No, it doesn't get tornadoes.


No. Tornadoes are dangerous.


Antarctica does not get tornadoes.


Yes, some strong tornadoes create brief satellite tornadoes that circle the main funnel.


No, tornadoes are caused by thunderstorms. Tornadoes and earthquakes are completely unrelated.


There is nothing to be "done" about tornadoes. Tornadoes are a natural weather event.
