  2. Anticyclonic rotation - Wikipedia

    en.wikipedia.org/wiki/Anticyclonic_rotation

    Large, low-pressure systems, such as tropical cyclones, have cyclonic rotation. Small scale rotating atmospheric features, such as tornadoes, water spouts, and dust devils can have either anticyclonic or cyclonic rotation, since the direction of their spin depends on local forces rather than the Coriolis effect.

  3. 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]

  4. Cyclone - Wikipedia

    en.wikipedia.org/wiki/Cyclone

    In meteorology, a cyclone (/ ˈ s aɪ. k l oʊ n /) is a large air mass that rotates around a strong center of low atmospheric pressure, counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere as viewed from above (opposite to an anticyclone). [1] [2] Cyclones are characterized by inward-spiraling winds that rotate ...

  5. High-pressure area - Wikipedia

    en.wikipedia.org/wiki/High-pressure_area

    A high-pressure area, high, or anticyclone, is an area near the surface of a planet where the atmospheric pressure is greater than the pressure in the surrounding regions. Highs are middle-scale meteorological features that result from interplays between the relatively larger-scale dynamics of an entire planet's atmospheric circulation .

  6. 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]

  7. Anticyclonic storm - Wikipedia

    en.wikipedia.org/wiki/Anticyclonic_storm

    The Great Red spot on Jupiter is considered as an Anticyclone storm system. [1] Anticyclonic cloud system taken above the Pacific Ocean by the STS-41-B crew.. An anticyclonic storm is a storm with a high-pressure center, in which winds flow in the direction opposite to that of the flow above a region of low pressure. [2]

  8. Category:Anticyclones - Wikipedia

    en.wikipedia.org/wiki/Category:Anticyclones

    Anticyclones generally bring fair weather and clear skies as the dynamics of an anticyclone lead to downward vertical movement which suppresses convective activity and generally lowers the mean relative humidity, in contrast to the upward vertical movement in a cyclone. However as the anticyclone moves over the earth surface it may heat up ...

  9. Mesocyclone - Wikipedia

    en.wikipedia.org/wiki/Mesocyclone

    Mesocyclones form when strong changes of wind speed and/or direction with height ("wind shear") sets parts of the lower part of the atmosphere spinning in invisible tube-like rolls. The convective updraft of a storm then draws up this spinning air, tilting the rolls' orientation upward (from parallel to the ground to perpendicular) and causing ...
