Modern Day[edit]
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.[1] During September 2001, RSMC La Reunion proposed that the basin adopt a single circular list of names and that a tropical cyclone have only one name during its lifetime.[2] However, both of these proposals were rejected at the fifteenth session of the RA I Tropical Cyclone Committee for the South-West Indian Ocean during September 2001.[2]
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.[3] However, it was decided to postpone the matter until the following committee meeting so that various consultations could take place.[3] 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.[4][5] 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.[5] 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.[5][6] 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.[6]
At its twenty-first session in 2015, the RA I Tropical Cyclone Committee reviewed the arrangements for naming tropical storms and decided that the procedure was in need of a "very urgent change".[7] In particular, it was noted that the procedure did not take into account any of the significant improvements in the science surrounding tropical cyclones and that it was biased due to inappropriate links with some national warning systems.[7] The committee subsequently decided that three lists of names would rotate from year to year, with any names used being automatically replaced at the next RA I Tropical Cyclone Committee.[7] During its twenty-third session in 2019, the committee noticed some inconsistency between the operational plan and the WMO technical regulations which defined the roles and responsibilities of tropical cyclone RSMC's.[8] As a result, the committee decided to acknowledge the authority of RSMC La Reunion and gave them the right to name tropical cyclones.[8]
