  22. BACKGROUND

  23. TORNADOE SEASON • The peak tornado season is late winter through midsummer,…. • But tornadoes can happen any time of the year when the atmospheric conditions are right.

  24. MISSOURI IS PART OF TORNADO ALLEY • TORNADOES HAVE OCCURRED IN EVERY STATE, BUT THEY OCCUR MOST FREQUENTLY IN “TORNADO ALLEY,” WHICH INCLUDES PARTS OF: TEXAS, OKLAHOMA, ARKANSAS, TENNESSEE, NEBRASKA, KANSAS, MISSOURI, ILLINOIS, AND IOWA.

  25. THE PHYSICS OF TORNADOES • TORNADOES ARE CAUSED BY THE COLLISION OF DESCENDING COLD AIR MASSESS COMING FROM THE NORTH AND ASCENDING WARM AIR MASSES COMING FROM THE SOUTH.

  26. THE PHYSICS OF TORNADOES • THE COLLISION CREATES A FUNNEL OF HIGH-VELOCITY WIND THAT IS VERY DESTRUCTIVE AS IT “TOUCHES DOWN” ONE OR MORE TIMES ALONG A LONG, NARROW (TYPICALLY 10-100 M) PATH.

  27. PHYSICS OF A TORNADO

  28. HAZARDS OF A TORNADO (AKA POTENTIAL DISASTER AGENTS) • WIND: SPEEDS CAN REACH 500 KM/HR (300 MI/HR) • PATH: CAN VARY FROM NARROW TO WIDE; SHORT TO LONG • THUNDER, LIGHTNING, AND HEAVY PRECIPITATION ARE TYPICAL • HAIL CAN BE VERY DAMAGING WITHIN A FEW MINUTES
