Tornadoes and thunderstorms have always been frequent in the U.S. However, advances in technology such as Doppler radar and cell phones have made it easier to detect and report such events.

Why is the US is prone to severe weather such as tornadoes and hurricanes?
Many parts of the world are prone to some form of violent weather. Hurricanes regularly affect the United States because it borders the waters of the Gulf of Mexico and tropical portions of the Atlantic Ocean, whose warm waters provide power to hurricanes. A large clockwise air circulation over the Atlantic will sometimes move hurricanes from the tropics up the U.S. East Coast. The portion of the U.S. between the Rockies and the Appalachians is particularly prone to tornadoes because of frequent collisions of warm moist air from the Gulf of Mexico, cool air from Canada and, in areas further west, dry air from the Rockies. These collisions can produce strong thunderstorms. With wind shear that often accompanies springtime storm systems these thunderstorms can start rotating, which allows them to produce tornadoes.
What state in the US has the most thunderstorms?
Florida
How many thunderstorms rage across the US every day?
about 10,000
In the US most tornadoes are classified as intense?
No. Intense tornadoes (those rated EF3 or higher) only account for about 3% of tornadoes in the U.S. Most tornadoes are rated as weak, EF0 or EF1.
What are the different kinds of weather and how does it helps?
the different kinds of weather are sunny cloudy rain snow sleet hail wind tornadoes hurricanes thunderstorms etc. sometimes it helps by giving us warm weather or good skiing weather or getting rain in a place that is experiencing a drought.
How much thunderstorms are in the US?
tornadoes.
Are tornadoes confined to US?
No. Tornadoes are possible just about everywhere there are thunderstorms.
Do tornadoes only happen in the US?
No. Tornadoes can occur almost anywhere that gets thunderstorms.
Where else in the world besides the US do tornadoes occur?
Everywhere that there are thunderstorms.
Are more frequent in the US than anywhere else in the world?
Tornadoes are more frequent in the US than anywhere else in the world.
When are tornadoes most frequent in the US?
late spring and early summer
Do tornadoes occur elsewhere in the world besides the US?
Yes. Tornadoes can occur almost anywhere that gets thunderstorms. Tornadoes have been recorded on every continent except Antarctica.
Why do few tornadoes happen in the western US?
Tornadoes are relatively rare west of the Rockies largely due to the dry climate, which is not very good for producing the violent thunderstorms that bring tornadoes.
Why do tornadoes in the US occur in the spring?
It is during the spring that there are may collisions between warm air and cold air. This causes thunderstorms which in turn can produce tornadoes.
Which term is used to reference the area of US which tornadoes are most frequent?
The term used for the region of the US where tornadoes frequently form is "Tornado Alley."
What would happen if we had no tornadoes?
Fewer homes would be destroyed in tornado-prone areas and we would not have storm cellars or tornado sirens. Severe thunderstorms would not be considered as dangerous as they are. Fewer people in the US would die from storms. Thunderstorms that would spawn tornadoes would expend their energy in some other way.
Where is tornado alley and why do tornadoes frequesntly form there?
Tornado Alley is in the heart of the US. Northern Texas, Oklahoma, Southwest Iowa, Eastern Colorado, and southern South Dakota. Tornadoes frequently form there because the jet stream mixes with the warm air from the Gulf of Mexico, forming severe thunderstorms that can lead to tornadoes.
