This measuring system was formerly known as the Saffir–Simpson hurricane scale, or SSHS. To be classified as a hurricane, a tropical cyclone must have one-minute-average maximum sustained winds at 10 m (33 ft) above the surface of at least 74 mph (64 kn, 119 km/h; Category 1). [ 1 ] The highest classification in the scale, Category 5 ...
Tropical cyclone wind speed climatology is the study of wind distribution among tropical cyclones, a significant threat to land and people. Since records began in 1851, winds from hurricanes, typhoons and cyclones have been responsible for fatalities and damage in every basin. Major hurricanes (Category 3 or above) usually cause the most wind ...
Beaufort scale. A ship in a force 12 (" hurricane -force") storm at sea, the highest rated on the Beaufort scale. The Beaufort scale (/ ˈboʊfərt / BOH-fərt) is an empirical measure that relates wind speed to observed conditions at sea or on land. Its full name is the Beaufort wind force scale.
The Saffir-Simpson Hurricane Wind Scale categorizes hurricanes based on their sustained wind speeds. This scale helps to estimate potential property damage. Hurricane categories. Category 1: Winds ...
The categories are defined by wind speed, with a storm of Category 3, 4, or 5 considered a major hurricane. And damage is exponential as wind speed increases, meaning a strong Category 3 storm ...
Accumulated cyclone energy (ACE) is a metric used to compare overall activity of tropical cyclones, utilizing the available records of windspeeds at six-hour intervals to synthesize storm duration and strength into a single index value. [1] The ACE index may refer to a single storm or to groups of storms such as those within a particular month ...
The Saffir–Simpson hurricane wind scale, assigns a numerical classification of hurricanes into five categories distinguished by the intensities of their sustained winds. The scale spans from Category 1 (winds of at least 74 miles per hour (119 km/h)) to Category 5 (exceeding 156 miles per hour (251 km/h)).
For the intensity scale, PAGASA lowered the threshold wind speed for classifying super typhoons from 220 km/h to 185 km/h and defined a super typhoon as an extreme tropical cyclone with 10-minute maximum sustained winds reaching 185 km/h or greater (the range of wind speed for typhoon category is consequently adjusted to 118–184 km/h).
