Slide3:  Winds can exceed 300 mph!!! Around 1,000 occur on average each year in the U.S. Kill 80, injure 1,500 people each year on average Can have a path up to a mile wide!!! Can occur any time of the year, but peak during the spring (March-June) Occur most frequently in the central U.S. in a region nicknamed “Tornado Alley” What Exactly Is A Tornado?:  What Exactly Is A Tornado? Violently rotating column of air (Vortex) extending from a thunderstorm to the ground How Do They Form?:  How Do They Form? Actually, no one knows for sure! But…We have a pretty good idea… Step 1:  Step 1 Before a t-storm, a change in wind direction and an increase in speed forms an invisible, horizontal spinning effect in the lower atmosphere (at the base of the storm) Step 2:  Step 2 Rising air within the t-storm (updrafts) tilts the rotating air from horizontal to vertical Step 3:  Step 3 Vertical rotation now extends 2-6 miles up into the t-storm. Now a tornado may form and extend from this area of rotation to the ground. Convection Demo:  Convection Demo Same basic principle behind a tornado vortex (funnel; column of fire in this case) Warm air moves up the vortex (updraft) Cools and sinks as it funnels out of the top (downdraft) The more air drawn in = faster and tighter spin This is called a convection cycle How Strong Are Tornados?:  How Strong Are Tornados? Strength is measured by the Fujita Scale... F0 = weakest, F5 = Strongest Are Most Tornados Strong?:  Are Most Tornados Strong? All tornados are potentially deadly, but most are actually relatively weak (74%)…! Only 1% of all tornados fall in the F4 – F5 range What’s Up With Xenia, OH?:  What’s Up With Xenia, OH? Xenia has been the target of several major tornados down through the years… Most recent: Sept. 2000 Most Notable: April 3, 1974 Sept. 2000 Damage:  Sept. 2000 Damage Where do you think this Tornado ranked on the Fujita Scale? April 3, 1974 Tornado:  April 3, 1974 Tornado April 3, 1974 Damage:  April 3, 1974 Damage Where do you think this tornado ranked on the Fujita Scale? Answers:  Answers Sept. 2000 = F3-F4 (Severe/Devastating Damage; Winds of 200-260 mph) April 1974 = F5 (Incredible Damage; Winds of 260-300+ mph!!!) Quick Review:  Quick Review Are most tornados strong or weak? Which would cause more damage, an F1 or an F5 tornado? During which season do most tornados occur in the U.S.? What is the nickname of the region in the U.S. where many tornados occur? What is used to classify the intensity of tornados? Bonus**: How do experts think tornados form? THE END:  THE END
