Overview of TornadoesDuring 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 ePortfolio on tornadoes.
What is a tornado? 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.

Formation of tornadosThe 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. (Natural Hazards, Keller, DeVecchio)

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

Tornado
The shrinking stageThough the name may make it seem less
harmful, during the shrinking stage, the winds can increase, making the tornado more destructive.

This occurs when a tornado encounters a downdraft
The tornado is still extremely dangerous in this stage

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.
