Naming tropical cyclones
Every so often, as occurred in 2020, the number of tropical cyclones in the Atlantic exceeds the list of names allotted for a given year. An alphabetical list of 21 names is used each year for Atlantic tropical cyclones, and the list repeats every six years. The protocol in the past has been, when the 21 names are exceeded, names for the letters of the Greek are used for additional tropical storms. The list of names has only been exceeded twice in history, which occurred in 2005 and 2020. Last year, 2020, was the most active Atlantic hurricane season ever recorded with a record of 30 named storms. There were 28 named storms in 2005.
Greek letters will no longer be used to name tropical storms
The World Meteorological Association (WMO) announced that it will no longer be using names of the Greek alphabet for naming tropical cyclones.
In a tweet, the WMO wrote: “The Greek alphabet will never be used again as it was distracting and confusing.”
For some time, going back as far as 2006, the World Meteorological Association (WMO) was in agreement that using Greek names as a supplemental list when the regular list of storm names was exceeded “was not practical,” The Verge reported. The group has now firmly decided that it will no longer use the names of the Greek alphabet.
According to the WMO, in addition to being confusing, the Greek names do not translate well to other languages as they have similar-sounding letters which lead to some miscommunication.
The WMO has created a list of supplemental names that will be used when the regular rotating lists have been exceeded. The list of supplemental names was released this week for both Atlantic and Pacific tropical cyclones.
Four storm names will be retired
Every year, the committee meets and selects names that caused so much damage and death that they should be removed from the rotating list so that their names stand apart in being identified with a specific storm.
The WMO announced that it will be retiring the names of three hurricanes from the 2020 Atlantic season which were especially devastating: Laura, Eta, and Iota. They will also retire the name Dorian from the 2019 season.
All of the retired names will have the year appended to them, for example, “Laura 2020” and “Dorian 2019.”
