  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. Anticyclonic rotation - Wikipedia

    en.wikipedia.org/wiki/Anticyclonic_rotation

    Anticyclonic rotation, or anticyclonic circulation, is atmospheric motion in the direction opposite to a cyclonic rotation.For cyclonic rotation, this motion is in a counter-clockwise direction in the Northern Hemisphere and clockwise in the Southern Hemisphere.

  6. 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]

  7. 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 ...

    Cyclone has origins in ancient Greek, the administration said. It likely came from from either κύκλος ( kúklos , “circle, wheel”) or κυκλόω ( kuklóō , “go around in a circle ...

  9. Low-pressure area - Wikipedia

    en.wikipedia.org/wiki/Low-pressure_area

    A clockwise spinning low-pressure area or cyclone of southern Australia. The center of the spiral-shaped cloud system is also center of the low. A low-pressure system over Iceland. In meteorology, a low-pressure area, low area or low is a region where the atmospheric pressure is lower than that of surrounding locations.
