  2. Overview of Tornadoes During class we have discussed tornadoes quite a bit, and even set a “goal” for the death count by the end of the semester (which we have yet to meet). In 1999, Salt Lake City was hit with a tornado and I remember, as a kid, going to see the destruction that it caused. I saw houses with roofs torn off, and pieces of, what was then, the Delta Center just lying on the ground. Having a personal recollection of this topic, I wanted to do my ePortfolioon tornadoes.

  3. What is a tornado? Science.howstuffworks.com Tornadoes form where there are large differences in atmospheric pressure over short distances. In class we compared this with the analogy of Jimmy Buffett down in Margaritaville running into some Cowboy’s.

  4. Formation of tornados Wall cloud • The organizational stage • This is where the tornado begins to form • Caused by updrafts developed in front of the advancing cold front and upwelling due to latent heat of condensation tilts the horizontally rotating air vertically.

  5. Mature Stage Tornado • In this stage of tornado formation, a funnel actually forms. • This is what we see when we think of a tornado Weathersavvy.com

  6. The shrinking stage Shrinking tornado Extremeplanet.me Though the name may make it seem less harmful, during the shrinking stage, the winds can increase, making the tornado more destructive.

  7. The rope stage Rope Stage Prairiestorm.blogspot.com • This is the final stage of a tornadoes’ process • This occurs when a tornado encounters a downdraft • The tornado is still extremely dangerous in this stage

  8. Tornado Classification Tornados are classified by the most damage they cause along their path They are classified on a scale called the Enhanced Fujita (EF) Scale

  14. My Experience • I remember after the tornado hit downtown SLC, my family and I drove up to see what it had actually done. I was amazed at the damage this twister had caused. • We had taken photos, but unfortunately after 14 years they have been misplaced. • This tornado opened my eyes a bit. It showed me that sever weather can occur here in Utah, and that we all need to be prepared for it.
