It is unknown as most countries to not keep records of their tornadoes. The United States averages between 1,200 and 1,300 tornadoes per year.
Australia has about 80 tornadoes every year.
It varies. Many days go without a single recorded tornado, while in some major tornado outbreaks, over 100 tornadoes may touch down in a day. To further complicate the issue, many tornadoes in developing nations or in sparsely populate areas go unreported. Based on tornadoes that are recorded though, there is an overall mean of 3 to 4 tornadoes per day, though few days actually see that number of tornadoes.
No. Although many hundreds of tornadoes are recorded every year, they often happen in outbreaks lasting a few hours to a few days.
From 2000 to 2010, 306 tornadoes touched down in Tennessee and another 5 touched down in other states and move into Tennessee.
The United States averages about 1200 tornadoes each year. Worldwide the number is less certain.
It varies widely, but the average is between 1,200 and 1,300.
Michigan averages about 15 tornadoes per year, though the number varies from year to year.

The number of tornadoes that occur worldwide is not known as most countries do not keep records of their tornadoes. Annually there are at least 1800 tornadoes recorded worldwide, but the number of actual tornadoes is much higher, perhaps several times higher.
Approximately than 1000 tornadoes touch down in the United States each year on average.
Yes. Many funnel clouds never touch down.
Worldwide statistics are not available as most countries do not keep records and some of those that do do not have them easily accessible. The U.S. where the greatest portion of tornadoes occur experienced 1075 tornadoes in 2000.
Official records indicate 75 to 80 percent of the world's tornadoes occur in the U.S. This statistic, however, is highly inaccurate as it only counts recorded tornadoes. The U.S. portion of the world's tornadoes is probably much smaller. The United States is a wealthy nation with plenty of resources to track down almost every tornado that touches down within its borders, including minor ones that do no more than topple a few trees. Many other countries do not conduct tornado surveys, resulting an many, if not most tornadoes going unrecorded. Tornadoes that touch down in very remote areas are also unlikely to be recorded.
24 tornadoes touched down in Minnesota in 2009.
Australia has about 80 tornadoes every year.
Every state has had at least a few weak tornadoes.
Tornadoes vary greatly in severity. Many tornado touch down in open fields and never cause any damage. At the other end, some tornadoes destroy entire towns and kill dozens of people.
