Most people who experience a tornado survive it. An F4 tornado will level most houses but in many cases a basement provides adequate protection. Even then, Only the strongest part of an F4 tornado has the power to produce F4 damage, so you have a good chance of being spared the worst of the tornado. On rare, and I put emphasis or rare, occasions people have even been carried by F4 tornadoes and lived.
Even an F5 tornado is survivable, partly because most buildings aren't hit by the full force of F5 winds.
As to the weaker categories mentioned in the first answer, An F3 tornado will usually leave at least a few interior walls standing so it is possible take shelter in a central room if you don't have a basement.
An F2 will tear the roof off a house and so, will probably is unlikely to kill or seriously hurt someone in a substantial structure. However, an F2 can completely destroy a trailer home which is a weak structure. A significant portion of tornado deaths are in trailers.
F1 tornadoes rarely kill, many deaths from tornadoes result from fallen trees and overturned trailers.
F0 tornadoes are even less likely to kill but they can still bring down trees.
Most tornadoes are weak and are not killers.
Consider the statistics; the United States gets more than 1000 tornadoes every year that usually kill a total of 60-80 people
Yes. Virtually all means of modeling tornadoes produce a vortex through some means.
A tornado is a kind of vortex so yes, in some ways.
A tornado is itself a kind of vortex, and can have smaller vortices inside of it.
Yes, every tornado has a vortex, which is the rapidly rotating column of air that extends from the base of the storm clouds to the ground. This vortex is what causes the destructive winds associated with tornadoes.
A vortex is a spinning or rotating movement in a liquid or gas. A tornado is a violently rotating column of air and thus is a type of vortex.
A vortex is a spinning flow of air or liquid. In a tornado, a vortex forms when warm, moist air meets cool, dry air, creating a rotating column of air that extends from the base of the storm cloud to the ground. This rotating vortex is what gives a tornado its destructive power.
A multiple vortex tornado has smaller, short-lived vortices moving around inside of it. The suction vortices have stronger winds than the rest of the tornado and are noted for cutting narrow curved swaths of intense damage. A multiple vortex tornado sometimes has the appearance of two or more tornadoes moving circles. A single vortex tornado is simply one vortex of tornadic wind.
No country does. A suction vortex is not a tornado; it is a feature that can develop in a tornado. A tornado itself is a vortex but can sometimes contain smaller vortices (vortexes) called suction vortices. Such a storm is called a multiple-vortex tornado.
A tornado is basically just a vortex of wind
There is no such thing as an actual tornado underwater, as a tornado is, by definition, a vortex of air. However, a vortex underwater is called a whirlpool.
A good hypothesis for a science fair project using a tornado vortex (tornado in a bottle) could be: "If the speed of rotation is increased in a tornado vortex model, then the strength and duration of the vortex will also increase." This hypothesis can be tested by varying the speed at which the bottle is rotated and observing the resulting vortex's characteristics, such as its height, stability, and longevity.
