Tornadoes are the most violent storms ever. They have caused deaths of many people. Then they also destroyed many buildings and acres of land. Many people are not friends with tornadoes as they sometimes destroy someone's business, and lead people's careers to an end. Also some people are just unlucky, because the country they live might have a lot of tornadoes.
A tornado is a dangerous rotating column of air, extending from a thunderstorm to the ground. You need warm air and cool air to form a tornado, then they make a change in wind direction and increase the wind speed. The wind rotates from horizontal to vertical which then creates a tornado. (Weather wiz kids) Damage paths can be found in excess of one mile wide and 50 miles long. Some

A funnel cloud is a rotating cone shaped column of air which is extending downward from a base of a thunderstorm. Also funnel clouds obviously depend on tornadoes because it's the storms which cause them. Tornadoes are the most dangerous weathers ever. About 1200 tornadoes on average hit the United States.

Tornados can happen at any time of the year. Opening windows or hiding under a bridge during a tornado, can be really dangerous. Tornado seasons cannot be forecasted. (weather wiz kids)
Also there is a couple of ways to measure tornadoes. The EF scale is the standard and most common way to measure tornadoes based on wind damage. The original Fujita scale was developed by Dr Theodore Fujita. All tornadoes were assigned a number according to the most intense damage this tornado has caused. The enhanced F scale started being used in the United States on February 1, 2007. The EF scale uses three second wind gusts, estimates based on a more detailed system for accessing the damage, which is also taking into account different building materials. (How to measure
