Severe Weather

  1. 1. Tornadoes by Briana Johnson<br />
  2. 2. What Tornados Come From<br />Tornados mostly start from great storm clouds called super cells. If the super cells get strong enough , they eventually turn into a tornado.<br />
  3. 3. Types of Tornados<br />Waterspout- weak tornado formed over water <br />Land Spout- equivalent to waterspout but formed over land<br />Multiple Vortex Tornado- a tornado that has more than one vortex, or a tornado with more than one spinning mass of cloud<br />Satellite Tornado- small and weak tornado that forms near a stronger tornado; doesn’t cause much damage to surroundings<br />
  4. 4. How Tornados Are Formed<br />A wall cloud, the type of cloud that often results in a tornado, is formed when warm air and cold air meet going in different directions and speeds. It starts a tornado usually when it reaches about 35 mph. The air pressure can range between 975 and 1000, and the precipitation and temperature can be anything.<br />
  5. 5. Where Tornados Mostly Appear<br />Tornados form in most places with hot, moist air. The place where tornados mostly happen is in Tornado Alley or the Great Plains. In that particular area, there are over 500 tornados each year. Think about that compared to everywhere else in America!<br />
  6. 6. Just Plain Creepy!!!<br />
  7. 7. Special Info<br />Where they most often occur- Tornado Alley or the Great Plains<br />Types of precipitation- any kind <br />Interesting types of tornados- waterspout, land spout, multi vortex, and suction vortexes, satellite tornado<br />Average wind speed- can range from speeds of 40 mph to 110 mph<br />
  8. 8. What Tornadoes Can Do<br />Tornadoes can move in speeds that range from 20-60 mph<br />Can make a strong updraft that can destroy or lift things of the ground in a matter of seconds<br />Can last for a few seconds, all the way to more than an hour<br />People can lose homes, family, and everything they own in the short but devastating time of a tornado<br />
  9. 9. One Great Storm(or not so great)<br />One of the worst storms of all time was the Tri-state Tornado of 1925. It caused the deaths of 695 people, the most deaths in America caused by one tornado in a period of 120 years! About 2,000 people were injured. It ran through Missouri, Illinois, and Indiana. It was the worst tornado in history.<br />
