  2. 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.

    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 ...

    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 ...

    en.wikipedia.org/wiki/Synoptic_scale_meteorology

    This corresponds to a horizontal scale typical of mid-latitude depressions (e.g. extratropical cyclones). Most high-and low-pressure areas seen on weather maps (such as surface weather analyses) are synoptic-scale systems, driven by the location of Rossby waves in their respective hemisphere.

    A bomb cyclone is defined as a mid-latitude cyclone over the Pacific Ocean that drops 24 millibars — a measure of atmospheric pressure — over 24 hours. This particular bomb could drop 50-60 ...

    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 ...

    en.wikipedia.org/wiki/Portal:Weather/Selected...

    Extratropical cyclones, sometimes called mid-latitude cyclones, are a group of cyclones that occur in the middle latitudes of the Earth, and which have neither tropical nor polar characteristics. They are connected with fronts and feature changes in temperature and dew point horizontally, otherwise known as "baroclinic zones".
