Subject: B1) How are tropical cyclones named? Contributed by Chris Landsea For listings of the current names being used see B2. Tropical cyclones are named to provide ease of communication between forecasters and the general public regarding forecasts, watches, and warnings. Since the storms can often last a week or longer and that more than one can be occurring in the same basin at the same time, names can reduce the confusion about what storm is being described. According to Dunn and Miller (1960), the first use of a proper name for a tropical cyclone was by Clement Wragge, an Australian forecaster late in the 19th century. He first designated tropical cyclones by the letters of various alphabets, then started using South Sea Island girls' names. When the new Australian government failed to create a federal weather bureau and appoint him director, he to took to naming cyclones "after political figures whom he disliked. By properly naming a hurricane, the weatherman could publicly describe a politician (who perhaps was not too generous with weather-bureau appropriations) as 'causing great distress' or 'wandering aimlessly about the Pacific.'". Although Wragge's naming practice lapsed when his Queensland weather bureau closed, fourty years later the idea inspired author George Stewart. In his 1941 novel "Storm", a junior meteorologist named Pacific extratropical storms after former girlfriends. The novel was widely read, especially by US Army Air Corp and Navy meteorologists during World War II. When Reid Bryson, E.B. Buxton, and Bill Plumley were assigned to Saipan in 1943 to forecast tropical cyclones they decided to name them (a' la Stewart) after their wives. In 1945, the armed services publicly adopted a list of women's names for typhoons of the western Pacific. From 1950 to 1952, tropical cyclones of the North Atlantic Ocean were identified by the phonetic alphabet (Able-Baker-Charlie-etc.), but in 1953 the US Weather Bureau switched to women's names after the Armed Services' practice. In 1979, under political pressure, the US National Weather Service (NWS) requested that the WMO's Region IV Hurricane Committee switch to a hurricane name list that alternated men's and women's names. The Northeast Pacific basin tropical cyclones were named using women's names starting in 1959 for storms near Hawaii and in 1960 for the remainder of the Northeast Pacific basin. In 1978, both men's and women's names were utilized. The Northwest Pacific basin tropical cyclones were given women's names officially starting in 1945 and men's names were also included beginning in 1979. As of 1 January 2000, tropical cyclones in the Northwest Pacific basin are now being named from a new and very different list of names. The new names are Asian names and were contributed by all the nations and territories that are members of the WMO's Typhoon Committee. These newly selected names have two major differences from the rest of the world's tropical cyclone name rosters. - The names by and large are not personal names. There are a few men's and women's names, but the majority are names of flowers, animals, birds, trees, or even foods, etc, while some are descriptive adjectives. - The names will not be allotted in alphabetical order, but are arranged by contributing nation with the countries being alphabetized. - The North Indian Ocean region tropical cyclones are named as of 2006. The Southwest Indian Ocean tropical cyclones were first named during the 1960/1961 season. The Australian and South Pacific region (east of 90E, south of the equator) started giving women's names to the storms in 1964 and both men's and women's names in 1974/1975.

TROPICAL CYCLONE NAMES for the NORTHWEST PACIFIC Contributed by Gary Padgett For over a half-century (since at least 1945) the military weather forecasters, initially members of the U. S. Navy and later also from the U. S. Air Force, have named tropical cyclones forming in the Northwest Pacific basin. The names utilized were almost exclusively English feminine names through 1978, but beginning in 1979 men's names were used with women's names in an alternating fashion. Also, starting in 1963 the meteorological service of the Philippines (now known as PAGASA) began assigning Filipino women's names ending in "ng" to tropical depressions and cyclones forming in or passing through PAGASA's area of warning responsibility. In 2002 a new naming scheme was adopted by PAGASA (see below). Beginning on 1 January 2000, tropical cyclones in the Northwest Pacific basin are named from a new and very different list of names. The new names are Asian names and were contributed by all the nations and territories that are members of the WMO's Typhoon Committee. The new names will be allotted to developing tropical storms by the Tokyo Typhoon Centre of the Japanese Meteorological Agency which is the RSMC for the basin. These newly selected names have two major differences from the rest of the world's tropical cyclone name rosters. One, the names by and large are not personal names. There are a few men's and women's names, but the majority are names of flowers, animals, birds, trees, or even foods, etc, while some are descriptive adjectives. Secondly, the names will not be allotted in alphabetical order, but are arranged by contributing nation with the countries being alphabetized. Fourteen nations or territories contributed ten names each for a total of 140 names. The first 42 names on the roster are: Western North Pacific (west of the dateline) Contributing Nation Names Cambodia Damrey Kong-reyNakri Krovanh Sarika China Haijui Yutu FengshenDujuan Haima DPR Korea Kirogi Toraji KalmaegiMujigae Meari Hong Kong Kai-Tak Man-yi Fung-wong Choi-wan Ma-on Japan Tembin Usagi Kanmuri Koppu Tokage Lao PDR Bolaven Pabuk PhanfoneChampi Nock-ten Macau Sanba Wutip VongfongIn-fa Muifa Malaysia Jelawat Sepat Nuri Melor Merbok Micronesia Ewinlar Fitow Sinlaku Nepartak Nanmadol Philippines Malaksi Danas Hagupit Lupit Talas RO Korea Gaemi Nari Jangmi Mirinae Noru Thailand Prapiroon Wipha Mekkhala Nida Kulap U.S.A.

Utor Matmo Etau Aere Vicete Vietnam Trami Halong Vamco Songda Saola * Bopha retired in 2012, replacement TBD PAGASA Names Since 1963 PAGASA has independently named tropical cyclones forming in the Philippines' AOR--from 115E to 135E and from 5N to 25N (except for a portion of the northwestern corner of the above region). Even though the Philippines contributed ten names to the international list of typhoon names, PAGASA still continues to assign their own names for local use within the Philippines. It is felt that familiar names are more easily remembered in the rural areas and that having a PAGASA- assigned name helps to underscore the fact that the cyclone is within PAGASA's AOR and potentially a threat to the Philippines. Another consideration may be PAGASA's desire to assign a name when a system is first classified as a tropical depression. Since tropical and/or monsoon depressions can bring very heavy rainfall to the nation which often results in disastrous flooding, the weather service feels that assigning a name helps to enhance public attention given to a system. Beginning with 2001 PAGASA began using new sets of cyclone names. These do not all end in "ng" as did the older names. Four sets of 25 names will be rotated annually; thus, the set for 2002 will be re-used in 2006. In case more than 25 systems are named in one season, an auxiliary set will be used.

Last updated May 10, 2013 Subject: B3) What storm names have been retired? Kindly provided by Gary Padgett, Jack Beven, James Lewis Free, and Sandy Delgado. In the Atlantic basin, tropical cyclone names are "retired" (that is, not to be used again for a new storm) if it is deemed to be quite noteworthy because of the damage and/or deaths it caused. This is to prevent confusion with a historically well-known cyclone with a current one in the Atlantic basin. Sometimes names are removed for other reasons, such as cultural considerations or politics. The following list gives the names that have been retired and the year of the storm in question. Retired hurricane names Atlantic Audrey 1957, Agnes 1972, Anita 1977, Allen 1980, Alicia 1983, Andrew 1992, Allison 2001 Betsy 1965, Beulah 1967, Bob 1991 Connie 1955 ,Carla 1961, Cleo 1964, Carol 1965, Camille 1969, Celia 1970, Carmen 1974, Cesar 1996, Charley 2004 Diane 1955, Donna 1960, Dora 1964, David 1979, Diana 1990, Dennis 2005, Dean 2007 Edna 1968, Eloise 1975, Elena 1985 Flora 1963, Fifi 1974, Frederic 1979, Fran 1996, Floyd 1999, Fabian 2003, Frances 2004, Felix 2007 Gracie 1959, Gloria 1985, Gilbert 1988, Georges 1998, Gustav 2008 Hazel 1954, Hattie 1961, Hilda 1964, Hugo 1989,Hortense 1996 Ione 1955, Inez 1966, Iris 2001, Isidore 2002, Isabel 2003, Ivan 2004, Ike 2008,Igor 2010 Janet 1955, Joan 1988, Juan 2003, Jeanne 2004 Klaus 1990, Keith 2000, Katrina 2005 Luis 1995, Lenny 1999, Lili 2002 Marilyn 1995, Mitch 1998, Michelle 2001 Noel 2007 Opal 1995 Paloma 2008 Roxanne 1995, Rita 2005 Stan 2005, Sandy 2012 Tomas 2010 Wilma 2005 Name retired because of previous storm in 1954 with the same name. Although rarer, some East Pacific names have been retired from the list. The climatology of this basin has most hurricanes moving away from the shore, so chances are rare that these storms would adversely affect people necessitating the name be retired. Retired hurricane names East Pacific Adele 1970, Adolph 2001, Alma 2008 Knut 1988, Kenna 2002 Hazel 1965 Iva 1988, Ismael 1995,Israel 2001 Pauline 1997 Name retired because of political considerations A few Central Pacific names have been retired from their list. Most of them were removed for inflicting damage or adversely affecting the Hawai'ian Islands. Retired hurricane names Central Pacific Fico 1978, Fefa 1991 Iwa 1982, Iniki 1992 Names retired before the 2000 season come from the name lists used by the Joint Typhoon Warning Center. Since 2000, the names removed come from the name lists used by the Japan Meteorological Agency. Most of the retired names inflicted significant damage to the nations affected.

In 1979, new name lists featuring both sexes were introduced and Bess was added back. In 1982, Bess was again retired and replaced with Brenda. Retired before being used Last updated May 19, 2011 Subject: B4) What is the origin of the word "hurricane"? Contributed by Chris Landsea "HURRICANE derived from 'Hurican', the Carib god of evil... alternative spellings: foracan, foracane, furacana, furacane, furicane,furicano, haracana, harauncana, haraucane, haroucana, harrycain, hauracane, haurachana, herican, hericane, hericano, herocane, herricao, herycano, heuricane, hiracano, hirecano, hurac[s]n, huracano, hurican, hurleblast, hurlecan, hurlecano, hurlicano, hurrican, hurricano, hyrracano, urycan, hyrricano, jimmycane, oraucan, uracan, uracano" From the AMS Glossary of Meteorology It should be noted that the Carib god 'Hurican' was derived from the Mayan god 'Hurakan', one of their creator gods, who blew his breath across the Chaotic water and brought forth dry land and later destroyed the men of wood with a great storm and flood . Subject: B5) What happens to the name of a tropical cyclone if it moves from the Atlantic regions to the Northeast Pacific, or vice versa? Contributed by Chris Landsea The rule used to be that if the tropical storm or hurricane moved into a different basin (see F1 for more about the basins), then it was renamed to whatever name was next on the list for the area. The last time that this occurred was in July 1996 when Atlantic basin Tropical Storm Cesar moved across Central America and was renamed Northeast Pacific basin Tropical Storm Douglas. The last time that a Northeast Pacific system moved into the Atlantic basin was in June 1989 when Cosme became Allison. However, these rules have now changed at the National Hurricane Center and if the system remains a tropical cyclone as it moves across Central America, then it will keep the original name. Only if the tropical cyclone dissipates with just a tropical disturbance remaining, will the tropical warning center give the system a new name assuming it becomes a tropical cyclone once again in its new basin. Subject: B6) What happens if they run out of names on the list? Contributed by Neal Dorst Well, we all found out the answer in 2005. In the Atlantic and East Pacific, when they have run through the name list they then use the Greek alphabet : Alpha, Beta, Gamma, Delta, Epsilon,... etc. . At present there are no plans to retire letters of the Greek alphabet from the list, but if a very bad hurricane occurs with a Greek letter name, this may have to be revised. In the Central and West Pacific they have a perpetual lists of names, so when one list is through they simply start on the next. Since the name list has been started in the Atlantic in 1950 the furthest they have gone down the list has been Tropical Storm Zeta in 2005. Revised May 8, 2007 Subject: B7) How can I nominate a new name for the list? Contributed by Frank Lepore (NHC) Since 1978, the United Nations' World Meteorological Organization, a group representing some 120 different countries, has used pre-determined lists of names for tropical storms for each ocean basin of the world. The Atlantic basin, which falls under Regional Association IV, has a six year supply of names with 21 names for each year. Why 21 names? Well, the letters Q, U, X, Y and Z are not used because names beginning with those letters are in short supply (you would need at least 3 male and 3 female names for each letter, plus a back-up supply for those retired). Think about it; how many men and women do you know whose names begin with these letters? When a damage or casualty producing storm like Mitch, Andrew,or Katrina strikes, the country most affected by the storm may recommend to the World Meteorological Organization's Regional Association that the name be "retired." Retiring a name is an act of respect for its victims, and reduces confusion in the insurance, legal or scientific literature. A retired name is replaced with a like-gender name beginning with the same letter. For example, Honduras recommended (1998) the name Mitch be retired and proposed the replacement name, Matthew, for consideration (and vote) by the 25-member countries of the Regional Association-IV. Seventy-seven names have been retired in the Atlantic basin. The names used on the list must meet some fundamental criteria. They should be short, and readily understood when broadcast. Further the names must be culturally sensitive and not convey some unintended and potentially inflammatory meaning. The potential for misunderstanding increases when you figure that in the Atlantic basin there are twenty-four countries, reflecting an international mix of English, Spanish and French cultures. Typically, over the historical record, about one storm each year causes so much death and destruction that its name is considered for retirement. This means that in a "normal" year, the odds are about 1 in 8 of requiring a replacement name, given that over the last 57 years (of reliable record) we've averaged slightly over 8 tropical storms and hurricanes per season (actually 8.6). So, it's more likely that letters/ names toward the front of the alphabet (letters A through H) might be retired. The Region IV Naming Committee has a rather large file folder of nominated names that have already been submitted. The next time the need arises and it's a storm affecting mainly the United States, the Committee will be casting about for a replacement tropical cyclone name. They will take out this file to make a selection. But as we say, it's pure chance from there. Last updated : May 20, 2011
