Great Storm of 1987 from Portland Bill, Dorset to Cromer, Norfolk the return period of the respective gusts were under 10 years. Sustained winds speeds greater than 75 mph were recorded for over an hour in southern Britain. According to the Beaufort scale of wind intensities, this storm had winds of hurricane force 12 (73 mph or greater); as the term "hurricane" refers to tropical cyclones originating in the North Atlantic or North Pacific, the descriptor "great storm" has tended to be reserved for those storms in recent years reaching this velocity. Hurricanes have a very different wind profile and distribution from storms, and
Wind gale-force winds lie between and with preceding adjectives such as moderate, fresh, strong, and whole used to differentiate the wind's strength within the gale category. A storm has winds of to . The terminology for tropical cyclones differs from one region to another globally. Most ocean basins use the average wind speed to determine the tropical cyclone's category. Below is a summary of the classifications used by Regional Specialized Meteorological Centers worldwide: The Enhanced Fujita Scale (EF Scale) rates the strength of tornadoes in the United States based on the damage they cause. Below is the scale. The station model
