Did You Know?

Credit for the invention of the word microburst is generally given to tornado expert Tetsuya Theodore Fujita. Fujita first described these extremely intense wind patterns in 1974. He noted that microbursts are usually short-lived, lasting only 5 to 15 minutes, but that they are extremely dangerous, especially for aircraft, because they cause sudden unexpected changes in wind direction or speed. Since the mid-1970s, many airports have installed Doppler radar systems to help detect potentially deadly microbursts.
