User:Jason Rees/SHEM naming history

SWIO

 * Wragge started it off in around 1892 naming all weather systems after politicians etc but his system died away after he retired.


 * Latter stages of World War 2 - Some tropical cyclones in the Southern Hemisphere were named by United States Armed Forces.


 * 1958-59 - The New Caledonia Meteorological Service introduced a naming scheme and started to assign female names to tropical cyclones in order to identify them in their public bulletins.


 * November 1962 - The New Caledonia Meteorological Service proposes to the third session of the World Meteorological Organizations Regional Association V, that all tropical cyclones in the region should be named using female names. Members of the association suggested that male names might have to be used instead of female names, in order to avoid any confusion with those names used in the Northern Hemisphere. These proposals were examined by the association, which realised that any naming or numbering scheme used on a regional basis, would need very close coordination to avoid confusion or duplication. The association suggested that there was no real need for a regional naming scheme in the Southern Hemisphere, but had no objections to members using a national naming scheme assuming that the names were not duplicated.


 * March 1, 1963 - The BoM established a tropical cyclone warning centre at Darwin.


 * October 1963 - The BoM holds a conference in Melbourne where they decide to follow international practises and name tropical cyclones using female names.


 * January 6, 1964 - TCWC Perth names Tropical Cyclone Bessie which was the first tropical cyclone to be formally named by the BoM.

I believe that what became Meteo France started naming in the SWIO at this stage.


 * 1969-70 - The Nadi office of the NZMS starts naming tropical cyclones.


 * January 4, 1970 - The Nadi Weather Office names Tropical Cyclone Alice.


 * October 10, 1970 - Fiji declares its independence from the United Kingdom.


 * December 21, 1974 – TCWC Darwin names Tropical Cyclone Tracy.


 * February 24. 1975 - The Australian Science Minister Bill Morrison announces that the BoM will use both male and female names from October 1, 1975.


 * During the 1970's, PNG appears to have had an annual list of names, while French Polynesia also appears to have named some systems in the 70s & 80s (Most notably TC Orama which along with Nisha is strangely not retired...)


 * September 16, 1975 - Papua New Guinea becomes independent from Australia.
 * October 1, 1975 - Male names start to appear
 * October 1, 1975 - The FMS becomes independent from the NZMS on October 1, 1975 and takes over the responsibility for naming tropical cyclones.


 * 1979-80 - The FMS starts using a rotating list of names.
 * 1979-80 - Papua New Guinea's list of names for the season was Kas, Lena, Mike, Noe, Owen, Peso, Hob, Suzy, Tau and Ati.


 * 1980-81 - The BoM appears to move to a circular list of names for each of its three TCWCs.


 * February 1983 - The French Polynesian Meteorological Service names Tropical Cyclone Nisha: Orama.


 * In 1985 the combination of TCs Nigel, Eric, Odette, Gavin and Hina impacting Vanuatu/Fiji prompt the formation of the RA V TCC.


 * January 1986 - The first session of the RA V Tropical Cyclone Committee takes place in Nadi, Fiji.


 * July 1988 - RA V TCC meets in Brisbane, Australia and updates the naming lists for Aus/SPAC.


 * October 1989 - The RA I TCC meets for its Ninth Session in Harare, Zimbabwe and invites the Seychelles Meteorological Service to submit names at its next sessions for the cyclone seasons between 1992-93 and 1999-2000.
 * 1996-97 - The BoM refreshes its naming liststhe


 * October 9 - 16, 1996 - At its sixth session, the RA V TCC prepares a list of names that have been retired/deleted from usage in RSMC Nadi's AOR between 1972-73 & 1995-96. THe names included were: Anne (1988), Bebe (1972), Betsy (1992), Bola (1988), Eric (1985), Esau (1992), Fran (1992), Harry (1989), Ima (1986), Issac (1982), Kina (1992-93), Joni (1992), Lin (1992), Lili (1989), Namu (1986), Nigel* (1985), Nina* (1992-93), Ofa (1990), Oscar (1983), Peni (1990), Polly (1993), Raja (1986-87), Sally, (1986-87), Theodore (1994), Tia (1991), Uma (1987), Val (1991), Veena (1983), Wally (1980), Wasa (1991).


 * February 25, 1997 - A tropical depression moved into MetService's area of responsibility on February 25, where it started to bear the hallmarks of a tropical cyclone, which prompted New Zealand's MetService to discuss naming the system with the Fiji Meteorological Service. At the time there was no precident of a tropical cyclone being named in the South Pacific to the south of 25&deg;S, while nobody was quite sure if MetService should take a name from the FMS list of names for the region or make one up. As a result, it was decided to treat the system as a depression operationally, before it was later classified as an unnamed tropical cyclone in post analysis.


 * September 8 - 12, 1998 - In its country report to the RA V Tropical Cyclone Committee's Seventh Session, MetService requests the right to name tropical cyclones in consulation with the FMS within its area of responsibility.


 * 1998-99 - New Zealand's MetService names TC Gita in conjunction with the FMS.


 * September 21 -27, 1999 - At the 14th RA I TCC, the committee decided the following:
 * A tropical cyclone would be named when its 10-minute average wind speeds reached 34 kn over half the circulation near the centre or the majority of the depression's circulation.</ref
 * In the absence of any objective measurements, naming was to take place as soon as the disturbance had been assigned a T2.5 number on the Dvorak scale for more than 6 consecutive hours.
 * A new code to identify tropical disturbances for operational monitoring and global climatology was to be introduced.
 * Two lists of names from A-Z containing both Male and Female first names were proposed for the 2000-2001 & 2001-2002 cyclone seasons.
 * 2000-01 - Ando, Bindu, Charly, Dera, Evariste, Francois, Gaby, Hans, Idriss, Jakoba, Kiran, Lanto, Mathieu, Nancy, Oda, Premnath, Quirin, Rakoto, Suzy, Tovo, Ursula, Vimla, Wenda, Xino, Yul and Zoe.
 * 2001-02 - Andre, Bako, Cyprien, Dina, Eddy, Francesca, Guillaume, Hary, Ikala, Jery, Kesiny, Lalita, Mirana, Naly, Orelie, Parina, Quincy, Roger, Solo, Teddy, Usha, Vero, Wendy, Xora, Yolande, Zaza.
 * It was proposed that tropical cyclones moving into the South-West Indian Ocean would not be renamed and would instead retain their original name. The committee agreed to examine this question more deeply and in detail during the following session of the committee.
 * The Committee noted a request from RSMC La Reunion to be given the role of naming tropical cyclones in the region and modified the procedures of naming a tropical cyclone to read: A tropical disturbance is named when reaching the stage of moderate tropical storm (validated T-number 2.5 on the Dvorak Scale over six consecutive hours). As soon as one of the two subregional Tropical Cyclone Advisory Centres (Madagascar if the storm is centred to the west of 55E and Mauritius if the storm is centred between 55E and 90E.) decides to name a disturbance, the RSMC La Reunion - TCC shall be informed immediately via fax and if necessary, by any other appropriate means to ensure that the given name appears in the bulletins issued by the RSMC.
 * It was proposed that the naming scheme would be reviewed at the next session.
 * The RA I TCC invited RA V TCC to consider a proposal for a single list of names in the Southern Indian Ocean, for use by each of the warning centres in the region.
 * In order to standardise the operational area of responsibility for tropical cyclones in the South-West Indian Ocean and the Global Maritime Distress and Safety System, the RA I TCC invited RA V TCC to consider a proposal to move the boundary for the SWIO and the Australian region from 90E to 95E.


 * September 2001 - At the 15th RA I TCC, the RA V TCC and RSMC La Reunion proposed that a tropical cyclone retained its original name when it moved into the SWIO from the Australian Region. RSMC La Reunion also proposed that the boundary of the Aus/SWIO be moved from 90E to 95E, that the basin adopts a single list of names that rotated from year to year and that the date of when the tropical cyclone year changed from August 1 to July 1. With the exception of the change to when the tropical cyclone year changed, these proposals were rejected by the RA I TCC who went on to approve the list of names for the 2002-03 and 2003-04 tropical cyclone years.


 * March 2004 - A tropical cyclone developed within the South Atlantic

During March 2004, a rare tropical cyclone developed within the Southern Atlantic, about 1010 km to the east-southeast of Florianópolis in southern Brazil. As the system was threatening the Brazilian state of Santa Catarina, a newspaper used the headline "Furacão Catarina," which was presumed to mean "furacão (hurricane) threatening (Santa) Catarina (the state)". However, when the international press started monitoring the system, it was assumed that "Furacão Catarina" meant "Cyclone Catarina" and that it had been formally named in the usual way.


 * November 2007 - The PNG NWS names TC Guba, which is automatically retired.


 * April 22, 2008 - TCWC Jakarta names their first tropical cyclone: Durga.


 * October 2008 - The RA I Tropical Cyclone Committee meets in Malawi for its eighteenth session.

At its 18th Session, the RA I TCC rejected a proposal that a tropical cyclone retained its original name, when it moved into the SWIO from the Australian Region but decided to discuss it at their next meeting after various consultations had taken place.


 * 2008-09 - TCWC Jakarta issues a naming list for its AOR.


 * 2008-09 - The BoM merges its three naming lists into one national list.


 * March 10, 2010 - Brazillian Weather Services name TC Anita


 * July 1, 2012 - The Mauritius Meteorological Service stops renaming tropical cyclones when they cross 90E.


 * September 2015 - At its 21st session in September 2015, the RA I TCC reviewed the procedures for naming tropical cyclones over the SWIO and decided that the procedures were in need of an overhaul. This was because it was felt that they did not take into account, significant improvements in the science around tropical cyclones and were biased by links to some national warning systems. As a result, they decided to form a task force which compromised off representatives from RSMC La Reunion, as well as the meteorological services of Mauritius and Madagascar, to develop an alternative procedure.  They also decided that there would now be three list of names that rotated on an annual basis with the names used automatically retired.


 * December 2018 - Concerns were raised by the JMA about names overlapping.


 * October 2019 - At the 23rd RA I TCC, the committee acknowledges that RSMC La Reunion has the right to name tropical cyclones.


 * 2021-22 - New Zealand's MetService names TC Eva in conjunction with the FMS.
