  2. Glossary of meteorology - Wikipedia

    en.wikipedia.org/wiki/Glossary_of_meteorology

    Also actiniform. Describing a collection of low-lying, radially structured clouds with distinct shapes (resembling leaves or wheels in satellite imagery), and typically organized in extensive mesoscale fields over marine environments. They are closely related to and sometimes considered a variant of stratocumulus clouds. actinometer A scientific instrument used to measure the heating power of ...

  3. Mesoscale convective system - Wikipedia

    en.wikipedia.org/wiki/Mesoscale_convective_system

    A mesoscale convective system's overall cloud and precipitation pattern may be round or linear in shape, and include weather systems such as tropical cyclones, squall lines, lake-effect snow events, polar lows, and mesoscale convective complexes (MCCs), and generally forms near weather fronts. The type that forms during the warm season over ...

  4. Mesoscale convective complex - Wikipedia

    en.wikipedia.org/wiki/Mesoscale_convective_complex

    The probability for severe weather is highest in the early stages of formation, during the afternoon. The MCC persists at its mature and strongest stage overnight and into the early morning in which the rainfall is characterized as stratiform rainfall (rather than convective rainfall which occurs with thunderstorms).

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

    In meteorology, an invest (short for "investigative area") [1] is a designated area of disturbed weather that is being monitored for potential tropical cyclone development. Invests are designated by three separate United States forecast centers: the National Hurricane Center , the Central Pacific Hurricane Center , and the Joint Typhoon Warning ...

  7. Mesoscale meteorology - Wikipedia

    en.wikipedia.org/wiki/Mesoscale_meteorology

    Mesoscale meteorology is the study of weather systems and processes at horizontal scales of approximately 5 kilometres (3 mi) to several hundred kilometres. It is smaller than synoptic-scale systems (1,000 km or larger) but larger than microscale (less than 1 km).

  8. Virga - Wikipedia

    en.wikipedia.org/wiki/Virga

    A shaft of precipitation that does not evaporate before reaching the ground is known in meteorology as a precipitation shaft. At high altitudes, precipitation falls mainly as ice crystals before melting and finally evaporating. That is often due to compressional heating, because air pressure increases closer to the ground.

  9. Meteorology - Wikipedia

    en.wikipedia.org/wiki/Meteorology

    Meteorology is a branch of the atmospheric sciences (which include atmospheric chemistry and physics) with a major focus on weather forecasting. The study of meteorology dates back millennia, though significant progress in meteorology did not begin until the 18th century. The 19th century saw modest progress in the field after weather ...
