This tornado occured in Oklahoma in 1999.
In the future tornado warnings will give the public so much time to take cover that the life loss will be reduced drasticly, but the only way that that is going to happen is if we can know when tornadoes are going to happen.
My design can help by taking a sensor and place it in the path of a tornado, get wind readings, preassure differentials, and temperature in the funnel itself. This site will tell you how I plan on doing that.
