Final answer:
The Fujita scale (F-scale) was updated to the Enhanced Fujita scale (EF-scale) in 2007. The EF-scale provides a more detailed and accurate assessment of tornado intensity based on a broader range of structural damage indicators. It was implemented to improve forecasting and analysis of tornadoes.
Step-by-step explanation:
The Fujita scale (F-scale) was updated to the Enhanced Fujita scale (EF-scale) in 2007. The EF-scale was developed as an improvement to the F-scale in order to more accurately classify tornadoes based on the damage they cause.
The F-scale, which was introduced in 1971 by Tetsuya Fujita, used wind speeds and damage descriptions to categorize tornadoes on a scale from F0 to F5. However, over time it was realized that the F-scale had limitations and needed updating.
The updated EF-scale, implemented in 2007, takes into account a broader range of structural damage indicators and the estimated wind speeds associated with each level. It provides a more detailed and accurate assessment of tornado intensity, aiding meteorologists in analyzing and forecasting tornadoes.
