The maximum sustained wind associated with a tropical cyclone is a common indicator of the intensity of the storm. Within a mature tropical cyclone, it is found within the eyewall at a distance defined as the radius of maximum wind, or RMW. Unlike gusts, the value of these winds are determined via their sampling and averaging the sampled ...
The most intense tropical cyclone (s) in the Australian Region were cyclones Gwenda and Inigo. By 10-minute sustained wind speed, the strongest were Cyclone Orson, Cyclone Monica and Cyclone Marcus. Storms with an intensity of 920 hPa (27.17 inHg) or less are listed.
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 ...
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 ...
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).
Within the basin, a super cyclonic storm is defined as a tropical cyclone that has 3-minute mean maximum sustained wind speeds of at least 120 knots (220 km/h; 140 mph). The category was formally introduced during the 1999 season alongside Very Severe Cyclonic Storms , in order to replace the previously used Severe Cyclonic Storm with Core of ...
Within the North Atlantic, intensification rates are on average fastest for storms with maximum one-minute sustained wind speeds of 70–80 kn (130–150 km/h; 80–90 mph). In the South-West Indian Ocean , intensification rates are fastest for storms with maximum ten-minute sustained wind speeds of 65–75 kn (120–140 km/h; 75–85 mph).
They also estimated that Veena had peaked with 10-minute sustained wind speeds of 211 km/h (131 mph) and a minimum pressure of 910 hPa (26.87 inHg). [2] During 2017, a study into extreme tropical cyclone activity in the southern Pacific Ocean was published in the Royal Meteorological Society 's International Journal of Climatology . [ 5 ]
