  2. Cyclonic rotation - Wikipedia

    en.wikipedia.org/wiki/Cyclonic_rotation

    Cyclonic rotation or cyclonic circulation is the atmospheric motion in the same direction as a planet's rotation, as opposed to anticyclonic rotation.In the case of Earth's rotation, the Coriolis effect causes cyclonic rotation to be in a counterclockwise direction in the Northern Hemisphere and clockwise in the Southern Hemisphere. [1]

  3. Cyclone - Wikipedia

    en.wikipedia.org/wiki/Cyclone

    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 ...

  4. Anticyclone - Wikipedia

    en.wikipedia.org/wiki/Anticyclone

    An anticyclone is a weather phenomenon defined as a large-scale circulation of winds around a central region of high atmospheric pressure, clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere as viewed from above (opposite to a cyclone). [1]

  5. High-pressure area - Wikipedia

    en.wikipedia.org/wiki/High-pressure_area

    The coriolis force caused by the Earth's rotation is what gives winds within high-pressure systems their clockwise circulation in the northern hemisphere (as the wind moves outward and is deflected right from the center of high pressure) and counterclockwise circulation in the southern hemisphere (as the wind moves outward and is deflected left ...

  6. Coriolis force - Wikipedia

    en.wikipedia.org/wiki/Coriolis_force

    Due to the Coriolis force, low-pressure systems in the Northern hemisphere, like Typhoon Nanmadol (left), rotate counterclockwise, and in the Southern hemisphere, low-pressure systems like Cyclone Darian (right) rotate clockwise. Schematic representation of flow around a low-pressure area in the Northern Hemisphere. The Rossby number is low, so ...

    en.wikipedia.org/wiki/Portal:Tropical_cyclones

    A tropical cyclone is a storm system characterized by a large low ... with anticlockwise rotation in the Northern Hemisphere and clockwise rotation in the Southern ...

  8. Earth's rotation - Wikipedia

    en.wikipedia.org/wiki/Earth's_rotation

    The Coriolis effect is mainly observable at a meteorological scale, where it is responsible for the opposite directions of cyclone rotation in the Northern and Southern hemispheres (anticlockwise and clockwise, respectively).

  9. Fujiwhara effect - Wikipedia

    en.wikipedia.org/wiki/Fujiwhara_effect

    Diagram of the Fujiwhara effect, showing how 2 tropical cyclones interact with each other. [1]When cyclones are in proximity of one another, their centers will circle each other cyclonically (counter-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere) [2] about a point between the two systems due to their cyclonic wind circulations.
