A "super-typhoon" is a term utilized by the U.S. Joint Typhoon Warning
Center in Guam for typhoons that reach maximum sustained 1-minute surface
winds of at least 130 kt (240 km/h). This is the equivalent of a strong
Saffir-Simpson category 4 or category 5 hurricane in the Atlantic basin or
a category 5 severe tropical cyclone in the Australian basin.
