Does the temperature of water affect the size of a tornado?

We hypothesize that the warmer the water temperature, the greater the diameter of a tornado. We built a tornado chamber to test our hypothesis. A pan of water was placed inside the Plexiglass chamber with water at different temperatures. We added dry ice which formed clouds. A bathroom exhaust fan created a spinning vertical tube of dry ice cloud, which allowed us to observe and photograph the results. Our tornadoes ranged in size from 4.5cm at 10 degrees celcius to almost 12cm at 100 degrees.
