    en.wikipedia.org/wiki/Tropical_cyclone

    A hurricane is a strong tropical cyclone that occurs in the Atlantic Ocean or northeastern Pacific Ocean, and a typhoon occurs in the northwestern Pacific Ocean. In the Indian Ocean and South Pacific, comparable storms are referred to as "tropical cyclones", and such storms in the Indian Ocean can also be called "severe cyclonic storms".

    In addition, the higher density air mass sweeping in behind the cyclone strengthens the higher pressure, denser cold air mass. The cold front over takes the warm front, and reduces the length of the warm front. [26] At this point an occluded front forms where the warm air mass is pushed upwards into a trough of warm air aloft, which is also ...

  4. Tropical cyclogenesis - Wikipedia

    en.wikipedia.org/wiki/Tropical_cyclogenesis

    Tropical cyclones are known to form even when normal conditions are not met. For example, cooler air temperatures at a higher altitude (e.g., at the 500 hPa level, or 5.9 km) can lead to tropical cyclogenesis at lower water temperatures, as a certain lapse rate is required to force the atmosphere to be unstable enough for convection.

  5. Tropical cyclone basins - Wikipedia

    en.wikipedia.org/wiki/Tropical_cyclone_basins

    Tropical Cyclones that develop within this basin generally affect countries to the west of the dateline, though during years of the warm phase of El Niño–Southern Oscillation cyclones have been known to develop to the east of the dateline near French Polynesia. On average the basin sees nine tropical cyclones annually with about half of them ...

    A "Typhoon" is a tropical cyclone located in the North-west Pacific Ocean which has the most cyclonic activity and storms occur year-round. 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.

    As warm, moist air rises from the ocean surface, winds begin to spin. The process is linked to how the Earth's rotation affects winds in tropical regions just away from the equator. Hurricanes ...

  9. Outline of tropical cyclones - Wikipedia

    en.wikipedia.org/wiki/Outline_of_tropical_cyclones

    Tropical cyclones develop or strengthen when water evaporated from the ocean is released as the saturated air rises, resulting in condensation of water vapor contained in the moist air. They are fueled by a different heat mechanism than other cyclonic windstorms such as nor'easters , European windstorms , and polar lows .
