dr. ted fujita. in 1971 he created what became known as the fujita scale.cribed as an f-1 or f-5 the f stands for ted fujita. the measurement is not just about wind speed. it's also about the damage caused. overtime engineers and meteorologists using the scale decided they could build a better system to account more accurately for different levels of damage. it was 2007 when they made a new scale. the enhanced fujita scale. you still have the same categories increasing in severity but this factors in enhanced specific criteria for evaluating the damage down to the level whether the tornado struck a single wide tornado home or double wide or the doctor's office. judging by all of those factors you determine how strong the tornado was. now they say ef-1. that means the enhanced fujita scale. the bigger the number, the worse it is. a storm with rating of five is incredible. it was the afternoon of may 3rd, 1999 when an f-5 tornado crossed into moore, oklahoma. the mayor today was also the same mayor then. he said the storm followed the same path of that huge o

dr. ted fujita of the university of chicago in 1971, he created what became known as the fujita scale for tornadoes. so when you hear a tornado described as f-0 or f-1, the f stands for fujita. an f-5 is the largest with winds of more than 260 miles per hour, even 300 miles per hour and more. but the measurement is not just about wind speed. it's also about the damage caused. over time engineers and meteorologists using the fujita scale decided they could build a better system to account more accurately for different levels of damage to different types of construction. so it was 2007 when they made a you new scale. the enhanced fujita scale. you still have the same categories from 0 to 5, but also factors in enhanced specific criteria for evaluating the damage down to the level of whether the tornado has struck a single wide mobile home or double wide or doctor's office. so you assign a specific degree p damage depending on whether it pushed in the doors or destroyed the wholt building. and judging by all of those factors and levels of debris determine how strong the tornado was. you used
