Tornadoes come from powerful thunderstorms called a super-cell. Tornadoes develop near low-pressure areas of high winds. The warm air moves up as the cold air moves down. Then when the warm air and the cold air hit together the main thunder storm is formed. After that, the cold air move under the warm air and then the warm air rushes up at fast speed. Finally the air create twisting, up drafts and causes a tornado. Tornadoes can usually last as long as regular thunder storm and can be vary destructive.

How Tornadoes Form

Tornadoes are the most destructive storms. They can have winds that can reach up to as high as 300 mph. They form when cold, dry, high pressure air blows over the Northern Great Plains and collides with warm, moist, low pressure air coming from the south. This warm air spins upward explosively forming a tornado.


Damage From a Tornado

Tornadoes can cause a lot of damages if they reach ground. They are natures deadliest storms. Tornadoes should always be taken serious, for they are very dangerous and are som

etimes deadly. Tornado winds can also reach to 300 mph. About 1/2 of tornadoes that occur cause as much damage as a F1 tornado. F0 through F3 tornadoes account for 80% of most tornadoes in the united states. About 1.1% of tornadoes that occur are F4 tornadoes. You should beware of tornadoes.


Types of Tornadoes

There are 6 types of destructive tornadoes. The first kind of tornadoes is a F0. A F0 often can reach up to around 73 mph or lower. A F0 causes little damage such as: broken chimneys, broken trees, sign damage. Another type of tornado is a F1. A F1 tornado can reach as low as 73 and as high as 112 mph. F1 tornadoes can cause roofs to peel off, mobile home to be flip or turned, and can blow cars off the road. The F2 tornado is the third type of tornado. A F2 can reach as low as 113 mph and can reach up to 157 mph. F2s can cause roofs to be torn off, mobile homes destroyed, large trees uprooted and snapped, and lift lift cars off the ground. There also F3 tornadoes. F3 tornadoes can go to 158 mph and up to 206 mph. F3s tornadoes can cause roofs and some wall to be ripped of well built houses, trains over turned, trees uprooted, and cars can be lifted or thrown. The next type of tornadoes are the F4s. They can go to at least 207 mph and can reach up to 260 mph. F4s can cause house to be leveled, and cars tossed and be created to be large missile generated. The final kind of tornado there is, is called the F5. They can go to as low as 261 mph and reach up to over 300 mph. F5s causes strong houses to be leveled or swept away, can trough cars up to 100 meters away, trees can be debarked, and incredible phenomena will occur. Finally, those are the six different types of tornadoes.


Safety Precautions

Finally, those are very helpful and important safety precautions during tornadoes.
