Tornadoes usually intensify when the parent storm intensifies. This can result from an increase in temperature and humidity. Tornadoes can also strengthen if there is greater convergence of air at lower levels.

∙ 8y agoBecause of their high wind speeds, they are really destructive.
The wind itself can be attributed to the fact that the pressure inside a tornado is much lower than its surroundings. A large pressure drop over a short distance will produce strong winds.

∙ 12y agoA tornado can be stronger than a hurricane in that they can attain greater wind speeds, about 300 mph in tornadoes vs. about 200 mph in hurricanes.
Tornadoes can produce much master winds than hurricanes.
Maximum winds in a tornado are likely around 300 mph, while in hurricanes they are closer to 200 mph.
Winds in tornadoes are stronger because the pressure drop takes place over a much shorter distance.

∙ 10y agoAs far as weather phenomena go, even large tornadoes are actually compartively small. Many of the largest tornadoes undergo a process called vortex breakdown, whereby a downdraft move through the center of the tornado, forcing the core to expand. Note, though, that many aspects of tornado dynamics are not fully understood.

How did the F-scale help scientist learn more about unpredictable tornadoes?
The Fujita scale does not help in predicting tornadoes, but it is a useful tool in statistical studies of tornadoes, where singling out stronger or weaker tornadoes is useful.
Has Hawaii ever had tornadoes?
Yes. Tornadoes do occasionally occur in Hawaii, but they are rare and none stronger than F2 have been recorded there.
Why are tornadoes becoming more dangerous for humans?
With increasing population growth and suburban sprawl there is more opportunity for tornadoes to kill people can cause major damage. The tornadoes themselves are not becoming stronger or more dangerous. In fact, the number of strong tornadoes in the United States has actually decreased in the past 60 years.
Does higher pressure make larger tornado's?
No. Stronger tornadoes (which are usually larger) have lower pressure than weak ones.
Do few tornadoes last more than a few minutes?
Correct, most tornadoes do not last more than a few minutes. Stronger tornadoes tend to last longer than weaker ones, though, so many of the major tornadoes that make national headlines will last more than just a few minutes.
Are hurricanes or tornadoes stronger?
Tornados are
Are little tornadoes stronger then bigger ones?
No. Usually the larger tornadoes are the stronger ones, but not always. There have been a few small but very violent tornadoes as well as large but fairly weak ones.
What percentage of tornadoes is considered strong?
About 20% of tornadoes are rated as strong (EF2 or stronger).
Are twisters stronger or more powerful than tornadoes?
No. Twisters and tornadoes are the same thing.
Which is more dangerous tornadoes or waterspouts?
Tornadoes are generally more dangerous as they are stronger than waterspouts.
Have Washington and Oregon ever had tornadoes?
Yes. Tornadoes do occur in Washington and Oregon. However, tornadoes stronger than F1 are rare.
Are tornadoes a serious threat to Tucson Arizona?
Not really. Although tornadoes can hit Tuscon, it is unusual and tornadoes stronger than EF1 are rare in Arizona.
Can tornadoes be formed by hurricanes?
Yes. It is farily common for hurricanes to produce tornadoes. However, a hurricane will rarely produce tornadoes stronger than EF2.
Does a tornadoes strength effect how long it last?
Generally stronger tornadoes last longer, though this is not always they case.
Why do tornadoes go longer if they spin faster?
Stronger tornadoes generally last longer because they have more energy.
What is stronger a small skinny tornado or a large tornado?
Generally large tornadoes are stronger but that is not always the case.
Are tornadoes a serious threat to Illinois and why?
Yes, tornadoes are a serious threat to Illinois. Violent tornadoes (EF4 or stronger) are a farily regular occurence in Illinois. These are the tornadoes that are known for devastating communities.
