The Globe Meteorological Firm (WMO) announced past week that it will no for a longer time use the names of Greek letters for hurricanes. Every yr the WMO follows a checklist of 21 names for Atlantic hurricanes. Previously, when additional storms arose, it would then apply letters in the Greek alphabet. The WMO suggests that strategy induced confusion and distraction in 2020, when there had been a file 30 Atlantic storms. From now on, it will publish a supplemental listing of appellations to draw on. This yr the extra Atlantic names contain Deshawn, Orlanda and Viviana. The firm also retires the names of especially fatal or destructive storms: these from the 2020 period are Laura, Eta and Iota, and Dorian is a late addition from 2019. All 89 earlier retired names are demonstrated in a Graphic Science column we published final summer months (beneath).
