The Fujita scale is used to measure tornadoes. This scale categorizes tornadoes based on the damage they cause to buildings and vegetation, providing ratings from F0 (weakest) to F5 (strongest). Established in 1971 by Dr. Ted Fujita, it takes into account the wind speed associated with the tornado's destruction. However, in 2007, an enhanced version called the Enhanced Fujita scale (EF scale) was introduced, refining the ratings to better correlate damage assessments. The Fujita scale effectively helps meteorologists and researchers understand tornado intensity and improve warning systems.
