Who developed the categories for hurricanes?
Saffir–Simpson scale
The scale was developed in 1971 by civil engineer Herbert Saffir and meteorologist Robert Simpson, who at the time was director of the U.S. National Hurricane Center (NHC).[1] The scale was introduced to the general public in 1973,[2] and saw widespread use after Neil Frank replaced Simpson at the helm of the NHC in 1974.[3]
Robert Simpson (meteorologist)
In 1967 Simpson became Deputy Director of the National Hurricane Center. Simpson reorganized NHC, making it separate from the Miami Weather Bureau office, and established the position of 'hurricane specialist' for NHC's senior forecasters. He directed NHC from 1968 to 1974, during which time he co-developed the Saffir-Simpson Hurricane Scale (SSHS) with Herbert Saffir, established a dedicated satellite unit at NHC, studied neutercanes, and began issuing advisories on subtropical storms. His controversial remarks to Vice President Spiro Agnew in the wake of Hurricane Camille led to an upgrade of the Air Force and Navy Hurricane Hunter squadrons, and persuaded NOAA (then ESSA) to improve their hurricane research aircraft.
