List of retired South Pacific cyclone names
Tropical cyclones are non-frontal, low-pressure systems that develop, within an environment of warm sea surface temperatures and little vertical wind shear aloft. Within the South Pacific, names are assigned from a pre-determined list, to such systems, once they reach or exceed ten-minute sustained wind speeds of 65 km/h (40 mph), near the center, by either the Fiji Meteorological Service or New Zealand's MetService.
