University of Chicago meteorologist Ted Fujita devised the Fujita Scale, the internationally accepted standard for measuring tornado severity. His goal was to create categories that could separate ...

Under the Enhanced Fujita scale, there are seven categories of storm. The lowest category is EFU, which is used for storms that don't have enough data or cause enough damage to be classified.

However, the Enhanced Fujita scale has a more intricate mechanism and is also designed to leverage the latest research on the topic. Is an EF5 tornado stronger than F5?

The Enhanced Fujita Scale, or EF Scale, is the scale used to estimate the wind speed of a tornado based on the damage it left behind. The Enhanced Fujita Scale replaced the Fujita scale Feb. 1, 2007.

The strength of tornadoes is rated on the Enhanced Fujita, or EF, Scale. The scale runs from 0 to 5 and rates tornadoes after they’ve hit by assessing damage to determine wind speed.

Fujita had an F-5 tornado producing 260 mph winds to 318 mph winds. The EF scale says an EF-5 tornado has winds over 200 mph. The EF scale also does not have an upper end on the EF-5 wind speed range.
