  2. 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]

  3. 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 ...

  4. 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 .

  5. Extratropical cyclone - Wikipedia

    en.wikipedia.org/wiki/Extratropical_cyclone

    Such blocking patterns are quite normal, and will generally result in a weakening of the cyclone, the weakening of the anticyclone, a diversion of the cyclone towards the anticyclone's periphery, or a combination of all three to some extent depending on the precise conditions. It is also common for an extratropical cyclone to strengthen as the ...

  6. Tropical cyclone - Wikipedia

    en.wikipedia.org/wiki/Tropical_cyclone

    A tropical cyclone is the generic term for a warm-cored, non-frontal synoptic-scale low-pressure system over tropical or subtropical waters around the world. [4] [5] The systems generally have a well-defined center which is surrounded by deep atmospheric convection and a closed wind circulation at the surface. [4]

  7. 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.

  8. 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.

  9. 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]
