![]() Selection process have changed with time: during the 80-90s for example, names were chosen by the National Meteorological Services in turn for several years (Madagascar at the end of the eighties-beginning of the nineties, Seychelles at the end of the nineties.). Since, both men's and women's names are utilized. Up to 1999-2000 tropical cyclones were named only using women's names. Each cyclone season starts with the letter A, and a name is normally only used once (but this has not always been true). Names are chosen from a predetermined list of names. In the Southwest Indian Ocean, tropical systems are named as soon as they become moderate tropical storms (33 knots). Subject B2) How are tropical cyclones names chosen in the Southwest Indian Ocean ? Source Philippe Caroff. 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. The North Indian Ocean region tropical cyclones are named as of 2006. The names will not be allotted in alphabetical order, but are arranged by contributing nation with the countries being alphabetized. 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 by and large are not personal names. These newly selected names have two major differences from the rest of the world's tropical cyclone name rosters. The new names are Asian names and were contributed by all the nations and territories that are members of the WMO's Typhoon Committee. 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 Northwest Pacific basin tropical cyclones were given women's names officially starting in 1945 and men's names were also included beginning in 1979. In 1978, both men's and women's names were utilized. 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 1979, the WMO and the US National Weather Service (NWS) switched to a list of names that also included men's names. The Southwest Indian Ocean tropical cyclones were first named during the 1960/1961 season.įrom 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. 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.' "ĭuring World War II, tropical cyclones were informally given women's names by US Army Air Corp and Navy meteorologists (after their girlfriends or wives) who were monitoring and forecasting tropical cyclones over the Pacific. He gave tropical cyclone names "after political figures whom he disliked. ![]() 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.Īnd Miller (1960), the first use of a proper name for a tropical cyclone was by an Australian forecaster early in the 20th century. Tropical cyclones are named to provide ease of communication between forecasters and the general public regarding forecasts, watches, and warnings. Subject B1) How are tropical cyclones named?
