Abstract : The mechanism (phases) of a developing tornado was investigated in this study on a laboratory model. Three existing theories for the mechanism of tornado formation were studied and discussed in length. From the information gained in this study an experimental facility was designed and constructed to approximate the fluid flow environment of the tornado. Vortices formed in this facility are considered similar to actual weak strength tornados. The mechanism for the formation of these vortices was deduced, using flow visualization techniques.
