In fact, it was ten years ago that researchers decided we needed something better than the F0-F5 rating system – the Fujita Scale. This change was in large part led by Professor Kishor Mehta, a Texas Tech civil engineer. He helped develop the new Enhanced Fujita Scale, or EF Scale. To more accurately measure the impact of tornadoes.
Mehta says the old system for measuring the severity of storms was developed in 1971, and assigned each tornado a rating based on the amount of damage meteorologists estimated it was capable of inflicting.
