The Enhanced Fujita Scale takes into account the quality of construction and standardizes different kinds of structures. The wind speeds on the original scale were deemed by meteorologists and engineers as being too high, and engineering studies indicated that slower winds than initially estimated cause the respective degrees of damage. [50]
The Enhanced Fujita Scale was formulated due to research that suggested that the wind speeds required to inflict damage by intense tornadoes on the Fujita scale are greatly overestimated. A process of expert elicitation with top engineers and meteorologists resulted in the EF scale wind speeds, but these are biased to United States construction ...
The instantaneous velocity readings taken are not directly equivalent to the three-second gust at 33 feet (10 m) that the Enhanced Fujita scale attempts to estimate, but they mark the second-highest wind speed ever recorded in a tornado, after wind speeds of approximately 135 m/s (300 mph) were recorded in both the 1999 Bridge Creek–Moore ...
The Enhanced Fujita scale measures a tornado's intensity on a scale of 1 to 5 based on its wind speed estimates and resulting damages. The Enhanced Fujita scale measures a tornado's intensity on a ...

The Fujita scale, Enhanced Fujita scale, and the International Fujita scale rate tornadoes by the damage caused. [1] [2] In contrast to other major storms such as hurricanes and typhoons, such classifications are only assigned retroactively. Wind speed alone is not enough to determine the intensity of a tornado. [3]
A unique feature of the International Fujita scale compared to the Fujita or Enhanced Fujita scale is a new damage indicator based on measured wind speeds. For the IF scale , only wind speeds measured at or below 10 metres (11 yd) can be used to determine a rating.
