  13. 13. The Supercell Storm</li></li></ul><li>Tornadoes<br /><ul><li>A narrow, violently rotating column of air that extends from the base of a thunderstorm to the groundWarm, Moist Air+Cool, Dry Air=Instability in Atmosphere </li></li></ul><li>Tornadoes<br />Tornado Intensity: Enhanced, Operational Fujita Scale:<br /><ul><li>EF0: 65-85mph: Light damage; Broken tree branches
  14. 14. EF1: 86-110mph: Moderate damage; Trees snapped, roofs damaged
  15. 15. EF2: 111-135mph: Considerable damage; Trees uprooted, Mobile homes demolished
  16. 16. EF3: 136-165mph: Severe damage; Cars lifted off ground, Trains overturned
  17. 17. EF4: 166-200mph: Devastating damage; Houses destroyed, Cars thrown 300 yards or more in air
  18. 18. EF5: Over 200mph: Incredible damage; Strongly built homes completely thrown away</li></li></ul><li>Hurricanes<br />Hurricanes occur when cool winds move over the very warm ocean waters in the summer. The cool air is forced up by the warm moisture of the ocean forming a hurricane.<br />Facts: <br /><ul><li>Can be up to 600 miles across
  19. 19. Speeds of 75-200 mph
  20. 20. Each one usually lasts over a week
  21. 21. Moves 10-20 mph over an open ocean
  22. 22. The “eye” is the calmest part</li></li></ul><li>Hurricane Stages<br />http://www.weatherwizkids.com/weather-hurricane.htm<br />
  23. 23. Floods<br /><ul><li>Flood: Overflowing of water onto land that is normally dryTypes of Floods:
  24. 24. River Floods
  25. 25. Coastal Flooding
  26. 26. Inland Flooding
  27. 27. Flash Flood (Most Dangerous)</li></li></ul><li>Floods<br />Flood Facts:<br /><ul><li>Number one weather-related killer in the US
  28. 28. Just 2 feet of water can float your vehicle (or even a bus!)
  29. 29. Six inches of rapidly moving water can knock you down
  30. 30. “Turn around, Don’t Drown!” 80% of flash flood deaths are auto-related</li></li></ul><li>Winter Storms<br />Usually develops when cold, dry air moves south and hits warm, moist air moving north.<br />Types of Weather During a Winter Storm:<br /><ul><li>Blizzards
  31. 31. Sleet
  32. 32. Freezing Rain
  33. 33. Lake-Effect Snow</li>
