  2. Maximum sustained wind - Wikipedia

    en.wikipedia.org/wiki/Maximum_sustained_wind

    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 ...

  3. Saffir–Simpson scale - Wikipedia

    en.wikipedia.org/wiki/Saffir–Simpson_scale

    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 ...

  4. List of the most intense tropical cyclones - Wikipedia

    en.wikipedia.org/wiki/List_of_the_most_intense...

    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.

  5. Wind speed - Wikipedia

    en.wikipedia.org/wiki/Wind_speed

    The fastest wind speed not related to tornadoes ever recorded was during the passage of Tropical Cyclone Olivia on 10 April 1996: an automatic weather station on Barrow Island, Australia, registered a maximum wind gust of 113.3 m/s (408 km/h; 253 mph; 220.2 kn; 372 ft/s) [6] [7] The wind gust was evaluated by the WMO Evaluation Panel, who found ...

  6. Typhoon - Wikipedia

    en.wikipedia.org/wiki/Typhoon

    Should the storm intensify further and reach sustained wind speeds of 48 knots (55 mph; 89 km/h) then it will be classified as a severe tropical storm. [19] Once the system's maximum sustained winds reach wind speeds of 64 knots (74 mph; 119 km/h), the JMA will designate the tropical cyclone as a typhoon—the highest category on its scale. [19]

  7. Beaufort scale - Wikipedia

    en.wikipedia.org/wiki/Beaufort_scale

    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.

  8. Cyclone - Wikipedia

    en.wikipedia.org/wiki/Cyclone

    t. e. In meteorology, a cyclone (/ ˈsaɪ.kloʊn /) is a large air mass that rotates around a strong center of low atmospheric pressure, counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere as viewed from above (opposite to an anticyclone). [1][2] Cyclones are characterized by inward-spiraling winds that rotate ...

  9. Accumulated cyclone energy - Wikipedia

    en.wikipedia.org/wiki/Accumulated_cyclone_energy

    Accumulated cyclone energy is calculated by summing the squares of the estimated maximum sustained velocity of tropical cyclones when wind speeds are at least tropical storm strength (≥ 34 kn; 63 km/h; 39 mph) [3] at recorded six-hour intervals. The sums are usually divided by 10,000 to make them more manageable.
