  2. Atlantic hurricane - Wikipedia

    en.wikipedia.org/wiki/Atlantic_hurricane

    The largest hurricane (in gale diameter winds) on record to form in the North Atlantic was Hurricane Sandy (2012) with a gale diameter of 870 miles (1,400 km). [52] The longest-lasting hurricane was the 1899 San Ciriaco hurricane, which lasted for 27 days and 18 hours as a tropical cyclone. [53]

    How do hurricanes form? Hurricanes, typhoons and cyclones begin as atmospheric disturbances - such as, for example, a tropical wave, an area of low pressure where thunderstorms and clouds develop ...

  4. Tropical cyclogenesis - Wikipedia

    en.wikipedia.org/wiki/Tropical_cyclogenesis

    Depth of 26 °C isotherm on October 1, 2006. There are six main requirements for tropical cyclogenesis: sufficiently warm sea surface temperatures, atmospheric instability, high humidity in the lower to middle levels of the troposphere, enough Coriolis force to sustain a low-pressure center, a preexisting low-level focus or disturbance, and low vertical wind shear. [3]

  5. Tropical cyclone - Wikipedia

    en.wikipedia.org/wiki/Tropical_cyclone

    Each year on average, around 80 to 90 named tropical cyclones form around the world, of which over half develop hurricane-force winds of 65 kn (120 km/h; 75 mph) or more. [1] Worldwide, tropical cyclone activity peaks in late summer, when the difference between temperatures aloft and sea surface temperatures is the greatest.

  6. Cyclone - Wikipedia

    en.wikipedia.org/wiki/Cyclone

    Tropical cyclones form as a result of significant convective activity, and are warm core. [11] Mesocyclones form as warm core cyclones over land, and can lead to tornado formation. [13] Waterspouts can also form from mesocyclones, but more often develop from environments of high instability and low vertical wind shear. [14]

    Wind shear is stiff breezes that can prevent a tropical storm from forming or cause a tropical storm or hurricane to weaken. When wind shear is low, it makes it easier for a tropical storm to form ...

    Of those 17 storms, 11 were hurricanes, including the catastrophic Hurricanes Helene and Milton. Hurricane season officially ends Nov. 30, though storms occasionally form in December.

  9. Atlantic hurricane season - Wikipedia

    en.wikipedia.org/wiki/Atlantic_hurricane_season

    The Atlantic hurricane season is the period in a year, from June 1 through November 30, when tropical or subtropical cyclones are most likely to form in the North Atlantic Ocean. These dates, adopted by convention, encompass the period in each year when most tropical cyclogenesis occurs in the basin.
