1. Weather - Tornadoes By: Jericho Dixon and Kory Tompkins

2. What Are Tornadoes? Tornadoes are one of the most violent and powerful types of weather. They consist of a very fast rotating column of air that usually forms a funnel shape. They can be very dangerous as their high speed winds can break apart buildings, knock down trees, and even toss cars into the air

3. How Tornadoes Form Tornadoes tend to form from very tall thunderstorm cloud called a cumulonimbus clouds. The typical steps to form a tornado are: 1.A large thunder storm occurs in a cumulonimbus cloud 2.Fast cold air at a high altitude is forced across warm air from the ground 3.The air between the cold and warm air begins to swirl horizontally 4.Warm air from the ground pushes up on the swirling air and tips it over 5.The funnel of swirling air begins to suck up more warm air from the ground 6.The funnel grows longer and stretches toward the ground 7.When the funnel touches the ground it becomes a tornado. The funnel of swirling air begins to suck up more warm air from the ground

5. Types of Tornadoes Supercell - A supercell is large long -lived thunderstorm. It can produce some of the largest and most violent tornadoes. Waterspout- A waterspout forms over warm water. They usually dissipate when they hit land. Land Spout – A land spout is similar to a waterspout but on land. It is week and is not associated with a vortex of air from a thunderstorm. Gustnado - A small tornado formed at a weather front by gust of wind. Multiple Vortex - A tornado with more then one spinning tube of air.

6. Tornado Categories Tornadoes are categorized by their wind speed and the amount of damage they cause using a scale called the “Enhanced Fujita” scale. It is usually abbreviated as the ”EF” scale.

7. Where Do Most Tornadoes Occur? Tornadoes can form most anywhere, but most of the tornadoes in the United States occur in an area called Tornado Alley. Tornado Alley stretches from northern Texas to South Dakota and from Missouri to the Rocky Mountains.
