    In the northern hemisphere, this is in a counterclockwise direction, and in the southern hemisphere, a clockwise direction. Usually, the tropical cyclones need to be within 1,450 kilometres (900 mi) of each other for this effect to take place.

  3. Typhoon - Wikipedia

    en.wikipedia.org/wiki/Typhoon

    A typhoon is a tropical cyclone that develops between 180° and 100°E in the Northern Hemisphere and which produces sustained hurricane-force winds of at least 119 km/h (74 mph). [1] This region is referred to as the Northwestern Pacific Basin, [2] accounting for almost one third of the world's tropical cyclones.

    The deep-layer mean flow is the best tool in determining track direction and speed. If storms are significantly sheared, use of a lower-level wind is a better predictor. Knowledge of the beta effect can be used to steer a tropical cyclone, since it leads to a more northwest heading for tropical cyclones in the Northern Hemisphere.

  5. Mesoscale convective system - Wikipedia

    en.wikipedia.org/wiki/Mesoscale_convective_system

    The term "cyclone" refers to such storms' cyclonic nature, with counterclockwise rotation in the Northern Hemisphere and clockwise rotation in the Southern Hemisphere. Depending on their location and strength, tropical cyclones are referred to by other names, such as hurricane, typhoon, tropical storm, cyclonic storm, tropical depression, or ...

    A polar cyclone is a low-pressure weather system, usually spanning 1,000 kilometres (620 mi) to 2,000 kilometres (1,200 mi), [54] in which the air circulates in a counterclockwise direction in the northern hemisphere, and a clockwise direction in the southern hemisphere. The Coriolis acceleration acting on the air masses moving poleward at high ...

    The strongest hurricane to reach land was the Labor Day Hurricane of 1935 (892 hPa). [12] The deadliest hurricane was the Great Hurricane of 1780 (22,000 fatalities). [54] The deadliest hurricane to make landfall on the continental United States was the Galveston Hurricane in 1900, which may have killed up to 12,000 people. [55]

    It often looks like several circles or a a cone going in a certain direction on the map that gradually gets larger. The cone gets larger to show a larger area of where the storm could go next, and ...

    Northern Hemisphere from above the North Pole. The Northern Hemisphere is the half of Earth that is north of the equator. For other planets in the Solar System, north is defined as being in the same celestial hemisphere relative to the invariable plane of the Solar System as Earth's North Pole. [1]
