In terms of duration a strong tornado typically lasts at least 20 minutes, and may last for over an hour. In terms of path length, most will travel at least 10 or 20 miles. Size is variable, but strong tornadoes are often 200 yards to at least 1/4 mile wide, wit some exceeding a mile.
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.
The Valetta tornado struck in 1551 or 1556, not in the 1900s. Since it was so long ago we can only guess at how strong it was.
No. The intensity of a tornado cannot be truly determined the intensity of a tornado until after it passes. A meteorologist can, based on radar, look for clues that a strong tornado is in progress, but there is a good deal of uncertainty. In long-term forecasts we can sometimes tell if a storm system has the potential to produce strong to violent tornadoes, but cannot determine where individual tornadoes will occur or how strong they will be, as every outbreak that produces strong tornadoes also produces weak ones.
Yes, especially if it is a strong tornado.
The strong wind in a tornado is the source of its destructive potential.
A supercell tornado is a tornado that forms from thunderstorm called a supercell. A supercell is a powerful thunderstorm that has a strong rotating updraft called a mesocyclone. Supercells are the strongest thunderstorms on earth. Most strong tornadoes are supercell tornadoes.
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.
A strong to violent tornado could potentially destroy a portion of it. But the area appears too large to be covered by a tornado.
Yes. In some cases a large, strong tornado will produce what is called a satellite tornado, which circles the main one.
