About Ted Fujita
Tetsuya Theodore Fujita was a Japanese and American meteorologist whose research primarily focused on severe weather. His research at the University of Chicago on severe thunderstorms, tornadoes, hurricanes, and typhoons revolutionized the knowledge of each. Although he is best known for creating the Fujita scale of tornado intensity and damage, he also discovered downbursts and microbursts and was an instrumental figure in advancing modern understanding of many severe weather phenomena and how they affect people, airplanes, and communities, especially through his work exploring the relationship between wind speed and damage. On June 12, 1982, Fujita observed an ongoing tornado for the first time. Fujita was also the first to widely study the meteorological phenomenon of the downburst, which can pose serious danger to aircraft. As a result of his work, in particular on Project NIMROD, pilot training worldwide routinely uses techniques he pioneered to provide instruction to students.
