Tropical cyclone scales 热带气旋等级
(重定向自Severe Tropical Storm)
Tropical cyclones are officially ranked on one of five tropical cyclone scales, according to their maximum sustained winds and which tropical cyclone basin(s) they are located in. Only a few scales of classifications are used officially by the meteorological agencies monitoring the tropical cyclones, but some alternative scales also exist, such as accumulated cyclone energy, the Power Dissipation Index, the Integrated Kinetic Energy Index, and the Hurricane Severity Index.
