cyclone names

Four lists of names are maintained by the World Meteorological Organization, rotating without regard to year, with the first name for a new year being the next name in sequence that was not used the previous year. Who names the names?

Before the formal start of naming, tropical cyclones were often named after places, objects, or saints' feast days on which they occurred. Written by Bob McDavitt, Meteorologist, Jan 2011 Tropical Depressions intensifying into tropical cyclones in all other areas between 90°E and 160°E as well as the Equator and 40°S are named by the Australian national weather service. Six lists of names are maintained by the World Meteorological Organization with them rotating on a yearly basis. the 2019 list will be used again in 2025. [1], Tropical cyclones that occur within the Northern Hemisphere between the anti-meridian and 100°E are officially named by the Japan Meteorological Agency when they become tropical storms. The names are used one after the other.

or costly that the future use of its name on a different storm would be This naming convention has been established by the World Meteorological Organization Tropical Cyclone Programme. For example, EP052019 indicates the 5th tropical depression in 2019 in the Eastern North Pacific. The National weather service of Mauritius name the storm should it intensify into a moderate tropical storm between 55°E and 90°E; if the storm should intensify into a moderate tropical storm between 30°E and 55°E then the national weather service of Madagascar assigns the appropriate name to the storm. [16], Within the North Indian Ocean between 45°E – 100°E, tropical cyclones are named by the India Meteorological Department (IMD/RSMC New Delhi) when they are judged to have intensified into cyclonic storms with 3-minute sustained wind speeds of at least 34 kn (39 mph; 63 km/h). National Hurricane Center

The left hand list is used sequentially. When the bottom of one list is Traditionally, the tropical cyclone formation areas are divided into seven basins (see map).

When a tropical depression intensifies into a tropical storm to the north of the Equator between the coastline of the Americas and 140°W, it will be named by the NHC. B : Bay of Bengal

Bureau Home > When a tropical or subtropical storm exists in the South Atlantic Ocean, the Brazilian Navy Hydrographic Center's Marine Meteorological Service names the system using a predetermined list of names. Names from List A are assigned in a random order while list B details replacement names for list A which will be added in the bottom of list A to maintain the alphabetical order. The six lists above are used in rotation and re-cycled every six years, i.e., the 2019 list will be used again in 2025.

Cyclone Amphan may may hit the West Bengal and Bangladesh coast by 20 May, 2020. Formal naming schemes and naming lists have subsequently been introduced and developed for the Eastern, Central, Western and Southern Pacific basins, as well as the Australian region, Atlantic Ocean and Indian Ocean. Names in bold will replace the adjacent names next time they are used. The names are intended to reduce confusion in the event of concurrent storms in the same basin.

* indicates replacement name not chosen yet. Before names are added to the Australian list, they are approved by neighbouring countries through Tropical cyclone formation is rare within the Mediterranean sea, South Atlantic and to the east of 120W in the Southern Pacific, as a result there are no official naming lists for these areas although in 2004 & 2010 when tropical cyclones formed within the South Atlantic they were named as Catarina and Anita. Tropical cyclones are named to help with communication about these dangerous storms. Their areas of responsibility extend across the regional boundaries of the Regional Specialized Meteorological Centres (RSMCs) of the WMO, which are outlined in red on the map. The RSMCs have regional responsibility to provide weather advisories, bulletins and warnings on tropical cyclones, while the TCWCs supplement this work by observing, naming and forecasting tropical cyclones. [7] The name "Kurumí" replaced "Kamby" in 2018 without being used. The hyperactive 2005 season wound up using six Greek names: Tropical Storm Alpha, Hurricane Beta, Tropical Storm Gamma, Tropical Storm Delta, Hurricane Epsilon and Tropical Storm Zeta… However, standards vary from basin to basin: some tropical depressions are named in the Western Pacific, while tropical cyclones must have a significant amount of gale-force winds occurring around the centre before they are named in the Southern Hemisphere. [12] The names of significant tropical cyclones are retired from the lists, with a replacement name selected at the next World Meteorological Organization's Hurricane Committee meeting. The only time that there is a change in the list is if a storm is so deadly Career Opportunities, National Oceanic and Atmospheric Administration, history of naming tropical cyclones and retired names, World Meteorological Organization tropical cyclone naming page. This page was last changed on 27 September 2020, at 05:21. Mu 13. tropical cyclone formed on December 28th, it would take the name from the previous In the event that more than twenty-one named tropical cyclones occur in the Atlantic basin in a season, additional storms will take names from the Greek alphabet.

[6] A replacement name is then submitted to the next World Meteorological Organization's RA V Tropical Cyclone Committee meeting. There are six lists of names which rotate every six years and begin with the letters A—Z used, skipping Q and U, with each name alternating between a male or a female name. These lists of names are applied to any storms in the Philippine area (5-25 °N and 115-135 °E) and are used in addition to the name given to the storm from the JMA list for the North-west Pacific, which are shown in parentheses. subsequent season's list of names. In the Australian list, the 2011 season started with Tasha, followed by Vince, then  Zelia. Significant tropical cyclones have their names retired from the lists and a replacement name selected at the next World Meteorological Organization Regional Association IV Hurricane Committee meeting.

W-HFO.webmaster@noaa.gov, Disclaimer For the history of naming, see, Central North Pacific Ocean (140°W to 180°), The names Ambali through Jeruto were automatically removed from the naming lists during the, Indonesian Agency for Meteorology, Climatology and Geophysics, Badan Meteorologi, Klimatologi, dan Geofisika, List of retired South Pacific cyclone names, Winter storm naming in the United Kingdom and Ireland, Regional Specialized Meteorological Center, 2019–20 South-West Indian Ocean cyclone season, Regional Association IV (North America, Central America and the Caribbean) Hurricane Operational Plan 2020, Typhoon Committee Operational Manual Meteorological Component 2019, Tropical Cyclone Operational Plan for the Bay of Bengal and the Arabian Sea: 2019, Tropical Cyclone Operational Plan for the South-West Indian Ocean: 2016, Tropical Cyclone Operational Plan for the South-East Indian Ocean and the Southern Pacific Ocean 2020, "NORMAS DA AUTORIDADE MARÍTIMA PARA AS ATIVIDADES DE METEOROLOGIA MARÍTIMA NORMAM-19 1a REVISÃO", "They Called the Wind Mahina: The History of Naming Cyclones", "Subject: Tropical Cyclone Names: B1) How are tropical cyclones named? Southern hemisphere storms are numbered in a single sequence irrespective of whether they are in the "S" or "P" areas.

Tropical cyclone names. Who names the names? If a cyclone severely impacts the coast, resulting in significant damage and potentially loss of life Tropical cyclones and subtropical cyclones are named by various warning centers to simplify communication between forecasters and the general public regarding forecasts, watches, and warnings.

[5][6], Any member of the World Meteorological Organization's hurricane, typhoon and tropical cyclone committees can request that the name of a tropical cyclone be retired or withdrawn from the various tropical cyclone naming lists. [6] Outside of these areas, the Australian Bureau of Meteorology names systems that develop into tropical cyclones. Should the list of names for a given year prove to be insufficient, names are taken from a reserve list of names, with the first ten published every year.[7]. Omicron 16.

Upsilon 21. The first storm of each year begins with the letter "A". Iota 10.

Should a tropical cyclone pass from one warning center to another it will retain its original name, except when moving into the South-West Indian Ocean where the Mauritius Meteorological Service will rename the system. [6] The names are assigned in alphabetical order and used in rotating order without regard to year. Names in bold will replace the adjacent names next time they are used.

Last names used in previous seasons in bold.

If a storm ever reached the magnitude that might otherwise have led to retirement, the storm would be listed with the retired names with a footnote indicating the Greek letter would still be available for future storms. They are now maintained and updated through The South Pacific tropical cyclone season runs from November to the end of April but it is not uncommon to get a tropical cyclone outside of these months. [8] This system of naming weather systems subsequently fell into disuse for several years after Wragge retired until it was revived in the latter part of World War II for the Western Pacific.

[6], If a system intensifies into a tropical cyclone between the Equator – 10°S and 141°E – 160°E, then it will be named by Papua New Guinea National Weather Service (NWS, TCWC Port Moresby). Delta 5.
