The warm air rises through the colder air, causing an updraft. Scientists have been wary of attributing the frequency and intensity of convective storms that can produce tornadoes to climate change, in part because historical and observational data around tornadoes is relatively limited. **Like the Fujita Scale, the Enhanced Fujita Scale is a set of wind estimates (not measurements of wind at the surface).
