By how strong the tornado is.
Even though strong tornadoes tend to be larger how strong a tornado is does not determine its size.
Relatively weak tornadoes have been very large and extremely strong tornadoes have been relatively small.
Simply put, Texas is bigger. Oklahoma actually has a higher concentration of tornadoes, but Texas is several times the size of Oklahoma, so there is more area for tornadoes to hit.
There is no definite size for an F3 tornado. F3 tornadoes have been recorded at sizes ranging from 100 yards to over 2 miles. Most, however are in the range of a quarter to a half a mile wide.
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.
There is no such thing as an F7 tornado. The maximum rating is F5. Even then, ratings for tornadoes are based on damage, not size.
It is not so much the biggest but the strongest tornadoes that are rated F5. The Fujita scale rates tornadoes from F0 to F5 based on how severe their damage is. F5 damage is the worst, it is complete destruction. F5 tornadoes tend to be very large, but aren't always. Size is not a factor in assessing tornado strength.
Tornadoes are rated based on the severity of the damage they cause, which is used to estimated wind speed. Although strong tornadoes tend to be larger, size is not an actual factor in rating tornadoes.
Most tornadoes are just a few yards wide when they touch down and grow to 50 to 100 yards wide at peak size.
No. Hurricanes and tornadoes are two different types of storm. Size is not the only difference.
No. Tornadoes vary greatly in strength, size, duration, speed of travel, and appearance.
No. Waterspouts are generally smaller than most tornadoes. Though a few are in the same size range that tornadoes typically fall into.
Tornadoes are not rated by size, they are rated by how severe the damage is from EF0 to EF5. For example if a tornado hits a town, destroying trailers and tearing off roofs but no worse, it is rated EF2, regardless of its size. Although tornadoes with higher ratings tend to be larger, this is not always the case.
It can happen, but it is rare. When tornadoes do merge it usually involves a large tornado absorbing a small one, so the size of the vortex will not be significantly influenced.
Tornadoes vary in strength, size, duration, speed of travel, color, location, and whether or not they are multiple vortex.
Definitely. In fact, Texas has the highest average number of tornadoes of any state in the U.S...This is due partially from it's large size (Oklahoma averages the highest number of tornadoes per square mile, but is a much smaller size than Texas)...Nevertheless, tornadoes are very common in Texas (Especially the northern and eastern parts of Texas)...
Yes. England actually gets a fairly high incidence for its size, but tornadoes stronger than F1 are very rare.
Simply put, Texas is bigger. Oklahoma actually has a higher concentration of tornadoes, but Texas is several times the size of Oklahoma, so there is more area for tornadoes to hit.
There is no set size. They can be fairly small tornadoes a few hundred yards wide or enormous wedges over a mile wide.
