  2. Tropical cyclogenesis - Wikipedia

    en.wikipedia.org/wiki/Tropical_cyclogenesis

    Tropical cyclogenesis involves the development of a warm-core cyclone, due to significant convection in a favorable atmospheric environment. [2] Tropical cyclogenesis requires six main factors: sufficiently warm sea surface temperatures (at least 26.5 °C (79.7 °F)), atmospheric instability, high humidity in the lower to middle levels of the ...

  3. Cyclogenesis - Wikipedia

    en.wikipedia.org/wiki/Cyclogenesis

    Cyclogenesis is the development or strengthening of cyclonic circulation in the atmosphere (a low-pressure area). [1] Cyclogenesis is an umbrella term for at least three different processes, all of which result in the development of some sort of cyclone , and at any size from the microscale to the synoptic scale .

    A tropical system in which the 10-minute maximum sustained winds are between 64–89 knots (74–102 mph; 119–165 km/h). [17] Tropical depression A tropical cyclone in which the maximum sustained surface wind speed (using the U.S. 1-minute average) is 33 kn (38 mph or 62 km/h) or less. [1] Tropical disturbance

    en.wikipedia.org/wiki/Cyclone

    Tropical cyclogenesis is the development and strengthening of a tropical cyclone. [28] The mechanisms by which tropical cyclogenesis occurs are distinctly different from those that produce mid-latitude cyclones. Tropical cyclogenesis, the development of a warm-core cyclone, begins with significant convection in a favorable atmospheric ...

    en.wikipedia.org/wiki/Portal:Tropical_cyclones

    A tropical cyclone is a storm system characterized by a large low-pressure center, a closed low-level circulation and a spiral arrangement of numerous thunderstorms that produce strong winds and heavy rainfall. Tropical cyclones feed on the heat released when moist air rises, resulting in condensation of water vapor contained in

    Maps show the areas impacted by storm surge, rainfall levels and more as Helene, once a major hurricane and now a tropical storm, moves inland from Florida's Gulf Coast over Georgia.

  8. Low-pressure area - Wikipedia

    en.wikipedia.org/wiki/Low-pressure_area

    Cyclogenesis is the development and strengthening of cyclonic circulations, or low-pressure areas, within the atmosphere. [3] Cyclogenesis is the opposite of cyclolysis, and has an anticyclonic (high-pressure system) equivalent which deals with the formation of high-pressure areas—anticyclogenesis. [4]
