There is some evidence that tornado frequency might be increasing but it is difficult to determine as with more advanced technology and greater knowledge of tornadoes we are now finding tornadoes that we would have previously missed.
Tornadoes are most common in the central and eastern parts of Mississippi. The frequency of strong tornadoes in those areas rivals that in parts of Tornado Alley.
The U.S. has 1,200 to 1,300 recorded tornadoes in an average year.
Global data is not available, but the US had 1075 recorded tornadoes in 2000.
It varies between regions. The U.S. overall averages about 1200 tornadoes per year. Canada gets about 100 per year. Most other countries do not keep records of tornadoes.
Yes. It will increase the standard deviation. You are increasing the number of events that are further away from the mean, and the standard deviation is a measure of how far away the events are from the mean.
There is no real evidence that the number of cyclones or tornadoes is increasing outside of normal fluctuation. The apparent number has increased as advanced technology has made us better able to detect and identify storms, and fast communications means we hear about more events sooner.

The frequency of tornadoes varies with the seasons but they can occur at any time of year.
Increasing the speed of the plunger will increase the frequency of the waves.
Assuming a constant wavelength, then increasing the wave speed will increase the frequency.
They don't. The US has 40 times the number of tornadoes that England has, and they tend to be much more intense- less than 10% of English tornadoes are strong, 42% of US tornadoes are strong storms.
The U.S. gets 75% of all recorded tornadoes. This is misleading however as many countries do not keep records of their tornadoes and the actual percentage of tornadoes for the U.S. is probably much smaller.
Hotspots for tornadoes in the United States include Tornado Alley, which covers parts of Texas, Oklahoma, Kansas, and Nebraska, as well as Dixie Alley in the southeastern US. Other regions prone to tornadoes include parts of the Midwest and Great Plains. Tornadoes can also occur in other parts of the world, but with less frequency than in the central US.
Oklahoma has had the most F4 and F5 tornadoes. Though it is tied with Texas, Iowa, and Alabama in terms of F5 tornadoes in the past 60 years.
Tornadoes in the U.S. are called tornadoes.
