  2. Tropical cyclone - Wikipedia

    en.wikipedia.org/wiki/Tropical_cyclone

    A tropical cyclone is the generic term for a warm-cored, non-frontal synoptic-scale low-pressure system over tropical or subtropical waters around the world. [4] [5] The systems generally have a well-defined center which is surrounded by deep atmospheric convection and a closed wind circulation at the surface. [4]

  3. Cyclone - Wikipedia

    en.wikipedia.org/wiki/Cyclone

    An extratropical cyclone is a synoptic scale low-pressure weather system that does not have tropical characteristics, [33] as it is connected with fronts and horizontal gradients (rather than vertical) in temperature and dew point otherwise known as "baroclinic zones". [34] "Extratropical" is applied to cyclones outside the tropics, in the ...

  4. Maximum sustained wind - Wikipedia

    en.wikipedia.org/wiki/Maximum_sustained_wind

    In most tropical cyclone basins, use of the satellite-based Dvorak technique is the primary method used to estimate a tropical cyclone's maximum sustained winds. [5] The extent of spiral banding and difference in temperature between the eye and eyewall is used within the technique to assign a maximum sustained wind and pressure. [6]

    The proportion of tropical cyclones reaching category four and five may increase by around 10% if global temperature rises are limited to 1.5C, increasing to 13% at 2C and 20% at 4C, the IPCC says ...

  6. Outline of tropical cyclones - Wikipedia

    en.wikipedia.org/wiki/Outline_of_tropical_cyclones

    Extratropical cyclone – a low-pressure system that is capable of producing weather conditions such as tornadoes, thunderstorms, gales, etc. Post-tropical cyclone – a former tropical cyclone that no longer has enough tropical quantities to be considered a tropical cyclone. Post-tropical cyclones, such as remnant lows, no longer possess ...

  7. Eye (cyclone) - Wikipedia

    en.wikipedia.org/wiki/Eye_(cyclone)

    The eye is a region of mostly calm weather at the center of a tropical cyclone. The eye of a storm is a roughly circular area, typically 30–65 kilometers (19–40 miles; 16–35 nautical miles) in diameter. It is surrounded by the eyewall, a ring of towering thunderstorms where the

    Almost all bomb cyclones have a precursor disturbance in the winds in the middle part of the troposphere - the lowest region of Earth's atmosphere - about 3-5 miles (5-8 km) above the planet's ...
