By contrast, the U.S. National Weather Service, Central Pacific Hurricane Center and the Joint Typhoon Warning Center define sustained winds as average winds over a period of one minute, measured at the same 33 ft (10.1 m) height, [16] [17] and that is the definition used for this scale.

The scale used for a particular tropical cyclone depends on what basin the system is located in; with for example the Saffir–Simpson hurricane wind scale and the Australian tropical cyclone intensity scales both used in the Western Hemisphere. All of the scales rank tropical cyclones using their maximum sustained winds, which are either ...
[1] [2] A named storm could also be classified as a Category 1 tropical cyclone if it is estimated, to have 1-minute mean maximum sustained wind speeds of between 64–82 knots (119–152 km/h; 74–94 mph) on the Saffir–Simpson hurricane wind scale.

Tropical cyclone scales – used to determine a cyclone's intensity, longetivity, and strength throughout its lifetime. Saffir-Simpson Hurricane Scale – a scale widely used by the National Hurricane Center, Central Pacific Hurricane Center, and the Joint Typhoon Warning Center to determine a storm's strength using maximum sustained winds.
Before the 1–5 scale was created in 1969 by the National Hurricane Center and later by the Bureau of Meteorology in Australia, many tropical cyclones were simply ranked by the Beaufort Wind Scale which was created in the early 1800s by Francis Beaufort. The purpose of the scale was to standardize wind reports in ship logs.
