Meteorologists and engineers look at the aftermath to determine the intensity of the winds.
It is possible to get a rough idea of how strong a tornado is by how fast its rotating.
It is believed that there is a calm "eye" at the center of a tornado. But mostly the winds in a tornado are very strong.

Strong tornadoes do not necessarily move faster, but the faster winds inside the tornado are the reason they're stronger. There are a number of factors affecting the strength of the winds inside a tornado and scientists still do not fully understand them. One factor simply has to do with the amount of energy in the atmosphere that can power a thunderstorm and thus a tornado. A thunderstorm also has to have strong rotation to produce a tornado, especially a strong one. If the rotation in a storm isn't strong enough, then not much of the energy will go into the winds of the tornado. Finally, the tornado's level or organization influences the winds it can generate. A disorganized tornado is unlikely to be able to focus its energy to produce the extreme winds seen in strong tornadoes.
Yes. A strong enough tornado could tear away the roof or walls, exposing the classroom to the wind and debris. A very strong tornado could could destroy the school
Yes, a very strong tornado can sweep it off its foundation and reduce it to rubble.
First, it is impossible to know how exactly strong a tornado is before it hits. But if a strong tornado is approaching you should be in your basement or storm cellar which is the safest place to be. Even if the tornado is an EF5 the portion of it with EF5 winds may still easily miss you.
The strong wind in a tornado is the source of its destructive potential.
It depends on how strong the tornado is. If its a weak tornado then most likely it can not, but if it's a very strong tornado it is very possible that it can.
A strong tornado is one that is EF2 or stronger. A violent tornado is one that is EF4 or EF5.
Yes, a tornado is a very strong windstorm.
A developing tornado can be detected by Doppler radar. This radar can measure wind speeds, and strong rotation withing a thunderstorm often indicates that at tornado is developing or is likely to develop.
Yes, especially if it is a strong tornado.
Scientists are still not sure how exactly a thunderstorm produces a tornado or why one storm will produce a tornado while another won't. They are still not sure what determines how strong or how large a tornado will be or how long it will last.
The Hallam, Nebraska tornado was rated F4
A typical tornado is probably a strong EF0 or EF1.
If you can see the tornado, strong tornadoes tend to be relatively wide, though not always. Additionally you can see the rotation in a tornado. If it is rotating very rapidly then it is probably strong. However, rotation that appears slower does not necessarily mean a weak tornado. Winds nearer the center or in subvortices hidden within the funnel may still be in the range of a strong to violent tornado.
The Xenia, Ohio tornado of April 3, 1974 was an F5, the strongest category of tornado.
