Tornado Model

We're Sullivan and Alexa and we're fascinated by tornados. Since studying real ones is dangerous, we decided to build our own tornado model to learn more about how these violent storms form. Our question: which is more important in forming a tornado, a sidewind or an updraft?

How would you investigate this question?
Tornadoes are a real challenge to study, so you probably want to think about building a tornado model. You'll need a set-up that has a wind blowing air from the side, and one blowing air upward. Think about which settings to use on each fan (low, medium, high), and how you'll determine which setting produce the most severe tornadoes. Describe your investigation in your notebook and discuss it with your teacher, or go to Tornados to learn what Sullivan and Alexa discovered.
