Beaufort scale used in Taiwan and mainland China, which are often affected by typhoons. Internationally, WMO Manual on Marine Meteorological Services (2012 edition) defined the Beaufort Scale only up to force 12 and there was no recommendation on the use of the extended scale. Wind speed on the 1946 Beaufort scale is based on the empirical relationship: Where "v" is the equivalent wind speed at 10 metres above the sea surface and "B" is Beaufort scale number. For example, "B" = 9.5 is related to 24.5 m/s which is equal to the lower limit of "10 Beaufort". Using this formula the highest
1932 Bahamas hurricane the churches were reportedly carried . Newspaper reports and photos helped to establish estimated prevailing winds on Green Turtle Cay that possibly exceeded during the hurricane. After the storm passed Abaco on September 6 and 7, several vessels caught in the storm recorded winds of Force 12 (Beaufort Wind Scale) and low barometric pressures; the steamship "Yankee Arrow" recorded a pressure of on September 7, while the nearby steamship "Deer Lodge" reported a lower pressure of . Although storm warnings were posted for the Florida and eastern United States coastline, the storm's recurvature prevented a landfall, leaving the main effects
