Rapidly rotating storm system characterized by a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain and/or squalls.- Tropical cyclone

Sudden, sharp increase in wind speed lasting minutes, as opposed to a wind gust, which lasts for only seconds.
Squalls are sometimes associated with hurricanes or other cyclones, but they can also occur independently.
Empirical measure that relates wind speed to observed conditions at sea or on land.
However, forces 13 to 17 were intended to apply only to special cases, such as tropical cyclones.
Rotational analog of linear momentum.
Conservation of angular momentum is also why hurricanes form spirals and neutron stars have high rotational rates.
Extratropical cyclones, sometimes called mid-latitude cyclones or wave cyclones, are low-pressure areas which, along with the anticyclones of high-pressure areas, drive the weather over much of the Earth.
In contrast with tropical cyclones, extratropical cyclones produce rapid changes in temperature and dew point along broad lines, called weather fronts, about the center of the cyclone.
Electrical storm or a lightning storm, is a storm characterized by the presence of lightning and its acoustic effect on the Earth's atmosphere, known as thunder.
Mesoscale convective systems formed by favorable vertical wind shear within the tropics and subtropics can be responsible for the development of hurricanes.
Difference in wind speed and/or direction over a relatively short distance in the atmosphere.
Strong vertical wind shear within the troposphere also inhibits tropical cyclone development but helps to organize individual thunderstorms into longer life cycles which can then produce severe weather.
Half of Earth that is north of the Equator.
Hurricanes and tropical storms (massive low-pressure systems) spin counterclockwise in the Northern Hemisphere.
In meteorology, rapid intensification is a situation where a tropical cyclone intensifies dramatically in a short period of time.
Large-scale movement of air and together with ocean circulation is the means by which thermal energy is redistributed on the surface of the Earth.
But every few years, the winters become unusually warm or unusually cold, or the frequency of hurricanes increases or decreases, and the pattern sets in for an indeterminate period.
An Atlantic hurricane or tropical storm is a tropical cyclone that forms in the Atlantic Ocean, primarily between the months of June and November.
