Frequently Asked Questions

What is the Enhanced Fujita (EF) Scale and how does it improve upon the original Fujita (F) Scale?

The Enhanced Fujita Scale (EF Scale) is a classification method used to estimate tornado wind speeds based on the damage left behind. It improves upon the original Fujita Scale by considering more variables, such as specific damage indicators (DIs) and degrees of damage (DOD), resulting in a more accurate estimation of wind speeds.

Why was the original Fujita Scale replaced by the Enhanced Fujita Scale?

The original Fujita Scale, developed in 1971, had limitations such as a lack of damage indicators, no account for construction quality and variability, and no definitive correlation between damage and wind speed. These limitations may have led to inconsistent ratings and an overestimate of tornado wind speeds. The Enhanced Fujita Scale was developed to address these limitations and provide more accurate estimation of wind speeds.

How are tornado wind speeds rated on the Enhanced Fujita (EF) Scale?

The Enhanced Fujita Scale (EF Scale) ranges from EF0 to EF5, with each rating corresponding to a specific range of wind speeds. For example, an EF3 tornado will have estimated wind speeds between 136 and 165 mph, whereas an F3 tornado (based on the original Fujita Scale) has winds estimated between 162-209 mph. The wind speeds necessary to cause “F3” damage are not as high as once thought, which the EF Scale takes into account.

Who has the authority to provide official tornado EF Scale ratings?

The National Weather Service (NWS), a federal agency, is the only authority responsible for providing official tornado Enhanced Fujita Scale ratings. NWS personnel use damage indicators (DIs) and degrees of damage to assess the wind speeds and assign an appropriate EF Scale rating to tornadoes.

How does the Enhanced Fujita (EF) Scale account for different types of damage?

The Enhanced Fujita Scale incorporates 28 damage indicators (DIs), including building type, structures, and trees, to assess the severity of tornado damage. For each damage indicator, there are 8 degrees of damage (DOD) ranging from the beginning of visible damage to complete destruction. The original Fujita Scale did not consider these details, making the EF Scale more comprehensive in its evaluation of tornado damage.

How do Doppler radar and storm spotters contribute to tornado warnings and the EF Scale?

Doppler radar technology allows meteorologists to detect tornadoes by analyzing storm rotation and identifying associated mesocyclones. Storm spotters, trained individuals who observe severe weather conditions on the ground, provide visual confirmation of tornadoes. Their observations and Doppler radar data can help assess tornado intensity and contribute to the assignment of an appropriate EF Scale rating.
