![]() Back to Tropical Cyclones Records Page | Back to Main FAQ Page Subject: E10) What are the average, most, and least tropical cyclones occurring in each basin? Contributed by Chris Landsea (NHC) and Sandy Delgado (NHC)
These values are based on data supplied by the WMO Regional Meteorological Center responsible for tropical cyclone forecasting for that particular basin. Starting in 1944, systematic aircraft reconnaissance was commenced for monitoring both tropical cyclones and disturbances that had the potential to develop into tropical cyclones in the Atlantic basin. This is why both Neumann et al. (1993) and Landsea (1993) recommend utilizing data since 1944 for computing Atlantic climatological statistics. However, for tropical cyclones striking the USA East and Gulf coasts - because of highly populated coastlines, data with good reliability extends back to around 1899. Thus, the following records hold for the entire Atlantic basin (from 1944-present) and for the USA coastline (1899-present). For other basins an appropriate starting date was selected for when satisfactory satellite coverage became available.
