Tropical cyclone naming

Last updated

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. The names are intended to reduce confusion in the event of concurrent storms in the same basin. Once storms develop sustained wind speeds of more than 33 knots (61 km/h; 38 mph), names are generally assigned to them from predetermined lists, depending on the basin in which they originate. Some tropical depressions are named in the Western Pacific, while tropical cyclones must contain a significant amount of gale-force winds before they are named in the Southern Hemisphere.

Before it became standard practice to give personal (first) names to tropical cyclones, they were named after places, objects, or the saints' feast days on which they occurred. Credit for the first usage of personal names for weather systems is generally given to Queensland Government Meteorologist Clement Wragge, who named systems between 1887 and 1907. When Wragge retired, the practice fell into disuse for several years until it was revived in the latter part of World War II for the Western Pacific. Formal naming schemes and lists have subsequently been used for major storms in the Eastern, Central, Western and Southern Pacific basins, and the Australian region, Atlantic Ocean and Indian Ocean.

Before the formal start of naming, tropical cyclones were often named after places, objects, or saints' feast days on which they occurred. The credit for the first usage of personal names for weather systems is generally given to the Queensland Government Meteorologist Clement Wragge, who named systems between 1887 and 1907. 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. Formal naming schemes have subsequently been introduced for the North Atlantic, Eastern, Central, Western and Southern Pacific basins as well as the Australian region and Indian Ocean. [8]

At present, tropical cyclones are officially named by one of eleven warning centers and retain their names throughout their lifetimes to facilitate the effective communication of forecasts and storm-related hazards to the general public. [9] This is especially important when multiple storms are occurring simultaneously in the same ocean basin. [9] Names are generally assigned in order from predetermined lists, once they produce one, three, or ten-minute sustained wind speeds of more than 65 km/h (40 mph). [1] [4] [5] However, standards vary from basin to basin, with some systems named in the Western Pacific when they develop into tropical depressions or enter PAGASA's area of responsibility. [3] Within the Southern Hemisphere, systems must be characterized by a significant amount of gale-force winds occurring around the center before they are named. [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. [1] [2] [6] A name is retired or withdrawn if a consensus or majority of members agree that the system has acquired a special notoriety, such as causing a large number of deaths and amounts of damage, impact, or for other special reasons. [1] A replacement name is then submitted to the committee concerned and voted upon, but these names can be rejected and replaced with another name for various reasons: these reasons include the spelling and pronunciation of the name, the similarity to the name of a recent tropical cyclone or on another list of names, and the length of the name for modern communication channels such as social media. [1] [2] [10] PAGASA also retires the names of significant tropical cyclones when they have caused at least

Within the North Atlantic Basin, tropical or subtropical storms are named by the United States National Hurricane Center (NHC/RSMC Miami), when they are judged to have 1-minute sustained winds of at least 34 kn (39 mph; 63 km/h). [1] The name selected comes from one of six rotating alphabetic lists of twenty-one names, that are maintained by the World Meteorological Organization's (WMO) RA IV Hurricane Committee. [1] These lists skip the letters Q, U, X, Y and Z, rotate from year to year and alternate between male and female names. [1] The names of significant tropical cyclones are retired from the lists, with a replacement name selected at the next meeting of the Hurricane Committee. [1]

Prior to 2021, if all of the names on the annual name list were used, additional tropical or subtropical storms would be named with Greek letters. In March 2021, the WMO announced any additional storms will receive a name from a supplemental list, to avoid confusion caused by the Greek letter names. [12]

Within the Eastern Pacific Ocean, there are two warning centers that assign names to tropical cyclones on behalf of the World Meteorological Organization when they are judged to have intensified into a tropical storm with winds of at least 34 kn (39 mph; 63 km/h). [1] Tropical cyclones that intensify into tropical storms between the coast of Americas and 140°W are named by the National Hurricane Center (NHC/RSMC Miami), while tropical cyclones intensifying into tropical storms between 140°W and 180° are named by the Central Pacific Hurricane Center (CPHC/RSMC Honolulu). [1] Significant tropical cyclones have their names retired from the lists and a replacement name selected at the next World Meteorological Organization Hurricane Committee. [1]

Eastern North Pacific (east of 140°W)

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. 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. [1] The names of significant tropical cyclones are retired from the lists, with a replacement name selected at the next meeting of the Hurricane Committee. [1] If all of the names on the annual name list are used, any additional tropical or subtropical storms will receive a name from a supplemental list. [12]

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. [2] However, PAGASA also names tropical cyclones that occur or develop into tropical depressions within their self-defined area of responsibility between 5°N–25°N and 115°E–135°E. [3] This often results in tropical cyclones in the region having two names. [3]

International names

Tropical cyclones within the Western Pacific are assigned international names by the Japan Meteorological Agency when they become tropical storms with 10-minute sustained winds of at least 34 kn (39 mph; 63 km/h). [2] The names are used sequentially without regard to year and are taken from five lists of names that were prepared by the ESCAP/WMO Typhoon Committee, after each of the 14 members submitted 10 names in 1998. [2] The order of the names to be used was determined by placing the English name of the members in alphabetical order. [2] Members of the committee are allowed to request the retirement or replacement of a system's name if it causes extensive destruction or for other reasons such as number of deaths. [2]

Since 1963, PAGASA has independently operated its own naming scheme for tropical cyclones that occur within its own self-defined Philippine Area of Responsibility. [3] [15] The names are taken from four different lists of 25 names and are assigned when a system moves into or develops into a tropical depression within PAGASA's jurisdiction. [3] [15] The four lists of names are rotated every four years, with the names of significant tropical cyclones retired if they have caused at least

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). [4] If a cyclonic storm moves into the basin from the Western Pacific, then it will keep its original name. [4] However, if the system weakens into a deep depression and subsequently reintensifies after moving into the region, then it will be assigned a new name. [4] In May 2020, the naming of Cyclone Amphan exhausted the original list of names established in 2004. [4] A new list of names has been prepared and is being used in alphabetical order for storms after Amphan. [4] [17]

Within the South-West Indian Ocean in the Southern Hemisphere between Africa and 90°E, a tropical or subtropical disturbance is named when it is judged to have intensified into a tropical storm with winds of at least 34 kn (39 mph; 63 km/h). [5] [18] This is defined as being when gales are either observed or estimated to be present near a significant portion of the system's center. [5] Systems are named in conjunction with Météo-France Reunion by either Météo Madagascar or the Mauritius Meteorological Service. [5] If a disturbance reaches the naming stage between Africa and 55°E, then Météo Madagascar names it; if it reaches the naming stage between 55°E and 90°E, then the Mauritius Meteorological Service names it. [5] The names are taken from three pre-determined lists of names, which rotate on a triennial basis, with any names that have been used automatically removed. [5] These names are then replaced by the WMO's RA I Tropical Cyclone Committee, with names submitted by member nations. [5]

Australian region (90°E – 160°E)

Within the Australian region in the Southern Hemisphere between 90°E – 160°E, a tropical cyclone is named when observations or Dvorak intensity analysis indicate that a system has gale force or stronger winds near the center which are forecast to continue. [6] The Indonesian Badan Meteorologi, Klimatologi, dan Geofisika names systems that develop between the Equator and 10°S and 90°E and 141°E, while Papua New Guinea's National Weather Service names systems that develop between the Equator and 10°S and 141°E and 160°E. [6] Outside of these areas, the Australian Bureau of Meteorology names systems that develop into tropical cyclones. [6] In order to enable local authorities and their communities in taking action to reduce the impact of a tropical cyclone, each of these warning centres reserve the right to name a system early if it has a high chance of being named. [6] If a name is assigned to a tropical cyclone that causes loss of life or significant damage and disruption to the way of life of a community, then the name assigned to that storm is retired from the list of names for the region. [6] A replacement name is then submitted to the next World Meteorological Organization's RA V Tropical Cyclone Committee meeting. [6]

Indonesia

If a system intensifies into a tropical cyclone between the Equator – 10°S and 90°E – 141°E, it will be named by the Badan Meteorologi, Klimatologi, dan Geofisika (BMKG/TCWC Jakarta). [6] Names are assigned in sequence from list A, while list B details names that will replace names on list A that are retired or removed for other reasons. [6]

Within the Southern Pacific basin in the Southern Hemisphere between 160°E – 120°W, a tropical cyclone is named when observations or Dvorak intensity analysis indicate that a system has gale force or stronger winds near the centre which are forecast to continue. [6] The Fiji Meteorological Service (FMS) names systems that are located between the Equator and 25°S, while the New Zealand MetService names systems (in conjunction with the FMS) that develop to the south of 25°S. [6] In order to enable local authorities and their communities in taking action to reduce the impact of a tropical cyclone, the FMS reserves the right to name a system early if it has a high chance of being named. [6] If a tropical cyclone causes loss of life or significant damage and disruption to the way of life of a community, then the name assigned to that cyclone is retired from the list of names for the region. [6] A replacement name is then submitted to the next World Meteorological Organization's RA V Tropical Cyclone Committee meeting. [6] The name of a tropical cyclone is determined by using Lists A–D in order, without regard to the year before restarting with List A. [6] List E contains names that will replace names on Lists A–D when needed. [6]

South Atlantic Ocean

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. The names are assigned in alphabetical order and used in rotating order without regard to year. [7] The name "Kurumí" replaced "Kamby" in 2018 without the latter being used. In 2022, 32 new names were added. [21]

The 2000 Pacific typhoon season marked the first year using names contributed by the World Meteorological Organization. It was a rather below-average season, producing a total of 23 tropical storms, 13 typhoons and 4 intense typhoons. The season ran throughout 2000, though typically most tropical cyclones develop between May and October. The season's first named storm, Damrey, developed on May 7, while the season's last named storm, Soulik, dissipated on January 4 of the next year.

<span class="mw-page-title-main">Typhoon</span> Types of tropical cyclone that develops in the Northern Hemisphere going to the eastern side

A typhoon is a tropical cyclone that develops between 180° and 100°E in the Northern Hemisphere and which produces sustained hurricane-force winds of at least 119 km/h (74 mph). This region is referred to as the Northwestern Pacific Basin, accounting for almost one third of the world's tropical cyclones. The term hurricane refers to a tropical cyclone in the north central and northeast Pacific, and the north Atlantic. In all of the preceding regions, weaker tropical cyclones are called tropical storms. For organizational purposes, the northern Pacific Ocean is divided into three regions: the eastern, central, and western. The Regional Specialized Meteorological Center (RSMC) for tropical cyclone forecasts is in Japan, with other tropical cyclone warning centres for the northwest Pacific in Hawaii, the Philippines, and Hong Kong. Although the RSMC names each system, the main name list itself is coordinated among 18 countries that have territories threatened by typhoons each year.

<span class="mw-page-title-main">1967 Pacific typhoon season</span> Typhoon season in the Pacific Ocean

The 1967 Pacific typhoon season was one of the most active Pacific typhoon seasons on record, witnessing the formation of 35 tropical storms during the season. It began on January 1, 1967, though most storms usually form between June and December within the basin. The first storm of the season, Ruby, formed on January 28 west of the Philippines. The scope of this article is limited to the Pacific Ocean, north of the equator and west of the international date line. Storms that form east of the date line and north of the equator are called hurricanes; see 1967 Pacific hurricane season. Tropical depressions that are monitored by the United States' Joint Typhoon Warning Center (JTWC) were given a numerical designation with a "W" suffix, and any storms reaching 1-minute sustained winds of over 40 mph were given a name. Tropical depressions that enter or form in the Philippine area of responsibility are assigned a name by the Philippine Atmospheric, Geophysical and Astronomical Services Administration or PAGASA. This can often result in the same storm having two names.

<span class="mw-page-title-main">Tropical cyclone scales</span> Scales of the intensity of tropical cyclones

Tropical cyclones are ranked on one of five tropical cyclone intensity scales, according to their maximum sustained winds and which tropical cyclone basins they are located in. Only a few scales of classifications are used officially by the meteorological agencies monitoring the tropical cyclones, but other scales also exist, such as accumulated cyclone energy, the Power Dissipation Index, the Integrated Kinetic Energy Index, and the Hurricane Severity Index.

A Regional Specialized Meteorological Centre (RSMC) is responsible for the distribution of information, advisories, and warnings regarding the specific program they have a part of, agreed by consensus at the World Meteorological Organization as part of the World Weather Watch.

<span class="mw-page-title-main">1997–98 Australian region cyclone season</span>

The 1997–98 Australian region cyclone season was a slightly below average tropical cyclone season. It ran from 1 November 1997 to 30 April 1998. The regional tropical cyclone operational plan also defines a tropical cyclone year separately from a tropical cyclone season, and the "tropical cyclone year" ran from 1 July 1997 to 30 June 1998.

<span class="mw-page-title-main">1998–99 Australian region cyclone season</span>

The 1998–99 Australian region cyclone season was an above average tropical cyclone season that featured Gwenda, the most intense tropical cyclone in the Australian Region. It began on 1 November 1998 and ended on 30 April 1999. The regional tropical cyclone operational plan also defines a tropical cyclone year separately from a tropical cyclone season, which runs from 1 July 1998 to 30 June 1999.

<span class="mw-page-title-main">History of tropical cyclone naming</span>

The practice of using names to identify tropical cyclones goes back several centuries, with storms named after places, saints or things they hit before the formal start of naming in each basin. Examples of such names are the 1928 Okeechobee hurricane and the 1938 New England hurricane. The system currently in place provides identification of tropical cyclones in a brief form that is easily understood and recognized by the public. The credit for the first usage of personal names for weather systems is given to the Queensland Government Meteorologist Clement Wragge, who named tropical cyclones and anticyclones between 1887 and 1907. This system of naming 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. Over the following decades, formal naming schemes were introduced for several tropical cyclone basins, including the North and South Atlantic, Eastern, Central, Western and Southern Pacific basins as well as the Australian region and Indian Ocean.

<span class="mw-page-title-main">Timeline of the 2014 Pacific typhoon season</span>

This timeline documents all of the events of the 2014 Pacific typhoon season. Most of the tropical cyclones forming between May and November. The scope of this article is limited to the Pacific Ocean, north of the equator between 100°E and the International Date Line. Tropical storms that form in the entire Western Pacific basin are assigned a name by the Japan Meteorological Agency. Tropical depressions that form in this basin are given a number with a "W" suffix by the United States' Joint Typhoon Warning Center. In addition, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) assigns names to tropical cyclones that enter or form in the Philippine area of responsibility. These names, however, are not in common use outside of the Philippines.

<span class="mw-page-title-main">Tropical cyclones in 2011</span>

During 2011, tropical cyclones formed within seven different tropical cyclone basins, located within various parts of the Atlantic, Pacific and Indian Oceans. During the year, a total of 131 tropical cyclones had formed this year to date. 71 tropical cyclones had been named by either a Regional Specialized Meteorological Center (RSMC) or a Tropical Cyclone Warning Center (TCWC). Thirty-nine of these named systems eventually intensified into hurricane-equivalent tropical cyclones. The most active basin in the year was the Western Pacific, which documented 21 named storms. North Atlantic basin documented 19 named storms, continuing the consecutive third-most active season trends from the previous year, due to the 2010–12 La Niña event. Conversely, the Eastern Pacific basin featured slightly more activity than the previous season, with 11 named storms. The least active basin in the year was the North Indian Ocean basin which documented only 2 named storms, the lowest since the 1993 season. Activity across the Southern Hemisphere were almost evenly spread, with the South-West Indian Ocean basin recording 10 tropical cyclones, the Australian region recording 17 tropical cyclones, and the South Pacific basin also recording 10 tropical cyclones, respectively. Twenty-one Category 3 tropical cyclones formed in the year, including three Category 5 tropical cyclones. The accumulated cyclone energy (ACE) index for the 2011, as calculated by Colorado State University was 573.8 units.

During 1991, tropical cyclones formed within seven different tropical cyclone basins, located within various parts of the Atlantic, Pacific and Indian Oceans. During the year, a total of 100 systems formed with 75 of these developing further and were named by the responsible warning centre. The strongest tropical cyclone of the year was Typhoon Yuri, which was estimated to have a minimum barometric pressure of 895 hPa (26.43 inHg). The deadliest tropical cyclone was Cyclone BOB 01, which caused 138,866 fatalities in Bangladesh, Northeastern India, Myanmar, Yunnan, while the costliest was Typhoon Mireille, which caused an estimated $10 billion USD in damage after striking Japan. Four Category 5 tropical cyclones formed in 1991.

<span class="mw-page-title-main">Tropical cyclones in 2008</span>

Throughout 2008, 124 tropical cyclones have formed in bodies of water known as tropical cyclone basins. Of these, 83 have been named, by various weather agencies when they attained maximum sustained winds of 35 knots. The strongest storm of the year was Typhoon Jangmi in the Western Pacific Ocean. The deadliest storm of the year was Cyclone Nargis, which caused devastating and castatrophic destruction in Myanmar with 138,373 fatalities. The costliest storm of the year was Hurricane Ike, which wreaked havoc thorough Cuba and Texas, with $38 billion in damage. Throughout the year, 24 Category 3 tropical cyclones formed, including one Category 5 tropical cyclone in the year. The accumulated cyclone energy (ACE) index for the 2008, as calculated by Colorado State University was 613.9 units.

The 2024 Pacific typhoon season is an ongoing event in the annual cycle of tropical cyclone formation in the western Pacific Ocean. The season runs throughout 2024, though most tropical cyclones typically develop between May and October.

<span class="mw-page-title-main">Tropical cyclones in 2024</span> Tropical cyclones in 2024 worldwide

In 2024, tropical cyclones will form in seven major bodies of water, commonly known as tropical cyclone basins. Tropical cyclones will be named by various weather agencies when they attain maximum sustained winds of 35 knots. So far, twenty-four systems have formed, with fourteen of them being named. The most intense storm of the year so far is Djoungou, with a minimum pressure of 922 hPa (27.23 inHg). Among this year's systems, so far, four have became a major tropical cyclone, with no tropical cyclones intensifying into Category 5 tropical cyclones on the Saffir–Simpson scale (SSHWS). The accumulated cyclone energy (ACE) index for the 2024 so far, as calculated by Colorado State University (CSU), is 98.7 units overall.
