  2. Middle latitudes - Wikipedia

    en.wikipedia.org/wiki/Middle_latitudes

    World map with the middle latitudes highlighted in red Extratropical cyclone formation areas. The middle latitudes, also called the mid-latitudes (sometimes spelled midlatitudes) or moderate latitudes, are spatial regions on either hemisphere of Earth, located between the Tropic of Cancer (latitude 23°26′09.8″) and the Arctic Circle (66°33′50.2″) in the northern hemisphere and ...

  3. Extratropical cyclone - Wikipedia

    en.wikipedia.org/wiki/Extratropical_cyclone

    The descriptor extratropical signifies that this type of cyclone generally occurs outside the tropics and in the middle latitudes of Earth between 30° and 60° latitude. They are termed mid-latitude cyclones if they form within those latitudes, or post-tropical cyclones if a tropical cyclone has intruded into the mid latitudes.

  4. Westerlies - Wikipedia

    en.wikipedia.org/wiki/Westerlies

    When the cyclone track becomes strongly poleward with an easterly component, the cyclone has begun recurvature, entering the Westerlies. [20] A typhoon moving through the Pacific Ocean towards Asia, for example, will recurve offshore of Japan to the north, and then to the northeast, if the typhoon encounters southwesterly winds (blowing ...

  5. Explainer-What are bomb cyclones and how do they form? - AOL

    A bomb cyclone, also referred to as explosive cyclogenesis or bombogenesis, is a mid-latitude cyclone that has rapidly intensified. A cyclone is a low-pressure weather system - one where the ...

  6. Synoptic scale meteorology - Wikipedia

    en.wikipedia.org/wiki/Synoptic_scale_meteorology

    In meteorology, the synoptic scale (also called the large scale or cyclonic scale) is a horizontal length scale of the order of 1,000 km (620 mi) or more. [1] This corresponds to a horizontal scale typical of mid-latitude depressions (e.g. extratropical cyclones).

  7. Polar front - Wikipedia

    en.wikipedia.org/wiki/Polar_front

    Atmospheric circulation diagram, showing the Hadley cell, the Ferrel cell, the Polar cell, and the various upwelling and subsidence zones between them. In meteorology, the polar front is the weather front boundary between the polar cell and the Ferrel cell around the 60° latitude, near the polar regions, in both hemispheres.

  8. Cyclone - Wikipedia

    en.wikipedia.org/wiki/Cyclone

    Cyclones have also been seen on extraterrestrial planets, such as Mars, Jupiter, and Neptune. [7] [8] Cyclogenesis is the process of cyclone formation and intensification. [9] Extratropical cyclones begin as waves in large regions of enhanced mid-latitude temperature contrasts called baroclinic zones.

  9. Australian east coast low - Wikipedia

    en.wikipedia.org/wiki/Australian_east_coast_low

    An east coast low on 27 July 2020 taken by Himawari 8. Australian east coast lows (known locally as east coast lows, maritime lows, and east coast cyclones [1]) are extratropical cyclones or low-pressure systems on the coast of southeastern Australia that may be caused by both mid-latitude and tropical influences over a variety of levels in the atmosphere.
