Fujita Tetsuya, Mr. Tornado, invented the scale for tornadoes

In 1971, Fujita Tetsuya (藤田 哲也), a professor at the Chicago University invented the index: “Fujita scale (F scale),” which measures the wind velocity of tornadoes in the United States. More than one thousand tornadoes a year are recorded globally and 3/4 of them are seen in the United States.
Tetsuya’s index became an international standard.
Moreover, he discovered the downburst (a descending jet stream) in 1975 and saved a lot of lives.

When he passed away at the age of 78 in 1998, the news conveyed great appreciation for him. Those who met him expressed their respects. Some comments included: “Meeting with him was equivalent to meeting with the Pope for me. His influence on a rainstorm science is immeasurable.”  “Perhaps, out of all the people I have met, Fujita is the most uniquely talented. I feel honored to have worked with him.” “He always reached his objective before his competitors. A lot of people got lost halfway through their research; however, Fujita’s report made things clear for them.”

Everyone praised his efficiency and wonderful personality. He took the time to explain his research earnestly and clearly to high school students. He was a good leader and was pleasant and energetic. Though he was not good at doing business, he had genuine originality and creativity to cover such weaknesses. Tetsuya Fujita was well respected.

For a period of time, core alumni members from Northern Kyushu, mainly his old school mates and his pupils of Meiji Vocational School (Kyushu Institute of Technology), took charge of Fujita’s facility, which took up 30 rooms on one floor at Chicago University. They are currently planning on calling the New Kitakyushu Airport “Fujita” for short and to have Fujita Tetsuya Memorial Hall in the airport.
