List of South-West Indian Ocean tropical cyclones
From Wikipedia, the free encyclopedia
Within the South-West Indian Ocean, the term tropical cyclone is reserved for those systems, that have winds of at least 65 knots (120 km/h; 75 mph). It is the third-highest classification used within the South-West Indian Ocean to classify tropical cyclones with.
Background
The South-West Indian Ocean tropical cyclone basin is located to the south of the Equator between Africa and 90°E.[1] The basin is officially monitored by Météo-France who run the Regional Specialised Meteorological Centre in La Réunion, while other meteorological services such as the Australian Bureau of Meteorology, Mauritius Meteorological Service as well as the United States Joint Typhoon Warning Center also monitor the basin.[1] Within the basin a tropical cyclone is a tropical system that has 10-minute maximum sustained wind speeds between 65–89 knots (120–165 km/h; 75–100 mph).[1]
