Background
[edit]During 1959, the Madagascan Weather Service introduced a naming scheme for significant tropical cyclones over the South-West Indian Ocean between Africa and 80°E that justified the issuance of a tropical cyclone warning to shipping.[1] Over the next year, the names were used liberally in the South African press before the Mauritius Meteorological Service started to name tropical cyclones with the agreement of the Madagascan Weather Service.[1]
In January 1960, a formal naming scheme was introduced for , by the Mauritius and Madagascan Weather Services with the first cyclone being named Alix.[2][3] Over the next few years the names were selected in various ways including by the meteorological services of the region for several years at a time, before it was turned over to the WMO's South West Indian Ocean Tropical Cyclone Committee at the start of the 2000–01 season.[4]
Ahead of the 2000–01 season, it was decided to start using male names, as well as female names for tropical cyclones developing in the South-West Indian Ocean.[5]
At its 15th session in September 2001, the committee noted a request from the RA V Tropical Cyclone Committee and RSMC La Réunion to ensure that a tropical cyclone only had one name during its lifetime.[6] RSMC La Réunion also proposed that the basin should adopt a single rotating list of names and that the start date of the season be moved from August 1 to July 1.[6] After a lengthy and detailed discussion, the committee agreed to change the start date of the season, but decided to not to change the naming procedures before approving the list of names for the 2002-03 and 2003-04 seasons.[6]
The issue of tropical cyclones being renamed when they moved across 90°E into the South-West Indian Ocean, was subsequently brought up during October 2008 at the 18th session of the RA I Tropical Cyclone Committee.[7] However, it was decided to postpone the matter until the following committee meeting so that various consultations could take place.[7] During the 2009 Tropical Cyclone RSMCs/TCWCs Technical Coordination Meeting, it was reaffirmed that a tropical cyclone name should be retained throughout a system's lifetime, including when moving from one basin to another, to avoid confusion.[8][9] As a result, it was proposed at the following year's RA I tropical cyclone committee, that systems stopped being renamed when they moved into the South-West Indian Ocean from the Australian region.[9] It was subsequently agreed that during an interim period, cyclones that moved into the basin would have a name attached to their existing name, before it was stopped at the start of the 2012–13 season.[9][10] Tropical Cyclone Bruce was subsequently the first tropical cyclone not to be renamed, when it moved into the South-West Indian Ocean during 2013–14.[10]
