    An anticyclone is a weather phenomenon defined as a large-scale circulation of winds around a central region of high ... Mean July subtropical ridge position in North ...

  3. 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 .

    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 ...

  5. 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]

  6. Block (meteorology) - Wikipedia

    en.wikipedia.org/wiki/Block_(meteorology)

    Rex blocks (or dipole blocks) consist of a high situated poleward (north in the Northern Hemisphere; south in the Southern Hemisphere) of a low. Very often both the high and the low are closed, meaning that the isobars (or constant geopotential height lines) defining the high–low close to form a circle. [9]

  7. Ridge (meteorology) - Wikipedia

    en.wikipedia.org/wiki/Ridge_(meteorology)

    Ridge line extending to the left of the high pressure center (H).In meteorology a ridge or barometric ridge is an elongated area of relatively high atmospheric pressure compared to the surrounding environment, without being a closed circulation. [1]

  8. Anticyclonic tornado - Wikipedia

    en.wikipedia.org/wiki/Anticyclonic_tornado

    An anticyclonic tornado is a tornado which rotates in a clockwise direction in the Northern Hemisphere and a counterclockwise direction in the Southern Hemisphere. [1] The term is a naming convention denoting the anomaly from normal rotation which is cyclonic in upwards of 98 percent of tornadoes.

  9. Tropical upper tropospheric trough - Wikipedia

    en.wikipedia.org/wiki/Tropical_upper...

    TUTTs sometimes bring a large amount of vertical wind shear over tropical disturbances in the deep tropics and cyclones and thus hinder their development. [3] However, there are cases in which TUTTs assist the genesis and intensification of tropical cyclones by providing additional forced ascent near the storm center and an efficient outflow channel in the upper troposphere.
