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

The shrinking stageThough the name may make it seem less

harmful, during the shrinking stage, the winds can increase, making the tornado more destructive.

The rope stageThis 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

Tornado ClassificationTornados are classified by the most damage

they cause along their pathThey are classified on a scale called the

Enhanced Fujita (EF) Scale

Where do tornadoes occur?Tornadoes are most common right here in the

USA We have the perfect combination of characteristics

to produce tornadoes

They do occur in other places in the world as well, just not as often

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.
