How does the Enhanced Fujita Scale classify tornadoes?
What will be the ideal response?
ANSWER: The Fujita scale classifies tornadoes according to their rotational wind speed. The tornado winds are estimated based on the damage caused by the storm. The Enhanced Fujita Scale, or simply the EF Scale, attempts to provide a wide range of criteria in estimating a tornado’s winds by using a set of 28 damage indicators, including small barns, mobile homes, schools, and trees. The quality of building construction is also taken into account. Each structure or object is examined for the degree of damage it sustained. The combination of the damage indicators along with the degree of damage provides a range of probable wind speeds and an EF rating for the tornado.
