  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]

    Post-tropical cyclones, such as remnant lows, no longer possess tropical quantities through either unfavorable conditions (e.g. increased wind shear) or land interaction. Pacific hurricane – a tropical cyclone that forms west of 100°W to the International Date Line in the Northern Hemisphere. The National Hurricane Center is responsible for ...

  4. Cyclone - Wikipedia

    en.wikipedia.org/wiki/Cyclone

    A tropical cyclone is a storm system characterized by a low-pressure center and numerous thunderstorms that produce strong winds and flooding rain. [45] A tropical cyclone feeds on heat released when moist air rises, resulting in condensation of water vapour contained in the moist air. [45]

  5. Low-pressure area - Wikipedia

    en.wikipedia.org/wiki/Low-pressure_area

    Monsoon troughs reach their northerly extent in August and their southerly extent in February. When a convective low acquires a well-hot circulation in the tropics it is termed a tropical cyclone. Tropical cyclones can form during any month of the year globally but can occur in either the northern or southern hemisphere during December.

    en.wikipedia.org/wiki/Fujiwhara_effect

    Diagram of the Fujiwhara effect, showing how 2 tropical cyclones interact with each other. [1]When cyclones are in proximity of one another, their centers will circle each other cyclonically (counter-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere) [2] about a point between the two systems due to their cyclonic wind circulations.

    2. A "Hurricane" is also a tropical cyclone located at the North Atlantic Ocean or North-east Pacific Ocean which have an average storm activity and storms typically form between May 15 and November 30. 3. A "Cyclone" is a tropical cyclone that occurs in the South Pacific and Indian Oceans.

  8. Eye (cyclone) - Wikipedia

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

    Cross section of a mature tropical cyclone. A typical tropical cyclone has an eye approximately 30–65 km (20–40 mi) across at the geometric center of the storm. The eye may be clear or have spotty low clouds (a clear eye), it may be filled with low-and mid-level clouds (a filled eye), or it may be obscured by the central dense overcast.

  9. Tropical cyclogenesis - Wikipedia

    en.wikipedia.org/wiki/Tropical_cyclogenesis

    Tropical cyclogenesis is extremely rare in the far southeastern Pacific Ocean, due to the cold sea-surface temperatures generated by the Humboldt Current, and also due to unfavorable wind shear; as such, Cyclone Yaku in March 2023 is the only known instance of a tropical cyclone impacting western South America.
