How Hurricanes are Named.
There were two alternatives for labeling hurricanes. The first was to label the hurricanes by year and sequence. For example the first hurricane of 1996 would be labeled 1:96. The only problem with this method developed in the 1940?s when meteorologists started exploring hurricanes by plane. Back then the form of communication was mainly in Morse code. ?—– —.. —-. …..? means 1:96 in Morse code. This was long and difficult for the pilots to write, so this method was soon disposed of.
Soon ship, and aircraft radios started using voice communication instead of Morse code. In 1951 American meteorologists started using the international phonetic alphabet for radios: Able, Baker, Charlie, Dog, etc. In the beginning of 1953 a new international alphabet was introduced: Alpha, Bravo, Cocoa, Delta, etc. This became confusing because one operator would report ?Hurricane Baker? and another would report ?Hurricane Bravo?. This became a nuisance because it was unclear if these were two different hurricanes, or the same hurricane. Near the end of 1953 meteorologists started using women’s names instead.
Naming hurricanes was not a new concept. For many years people in the West Indies had named hurricanes after the saint on who?s day they struck. One example of this was a storm that swept across Puerto Rico on July 26, 1825, was known as Santa Ana. Personal names were also used in other locations such as Canada. Some meteorologist have been giving hurricanes women?s names since the late nineteenth century.
Women?s names were used until 1978 when lists in the Eastern Pacific used Men?s names. This method still remains. The names alternate between men, and women, for example Andrew, Bonnie, Charley, Danielle, etc. In 1979, these lists also started to include names from non-english-speaking-cultures. Since these names were used instead of the phonetic alphabet they were put in alphabetical order, for example in 1995 the first Atlantic Hurricane was called Allison, then Barry, and so on. Since Hurricanes, and Pacific typhoons use the same method to choose their names six different lists where created. These lists were recycled every six years, So in 1990 one list was used and six years later in 1996.
Some names have been retired because their hurricanes have caused such devastating destruction. They did this so that people would not get confused between hurricanes. For example if Hurricane Bonnie killed many people in 2001 and did again in 2010 then people might be confused between which hurricane it is. the names that have been retired are, Agnes (1972), Andrew (1992), Camille (1969), Gilbert (1988), and Hugo (1989).
