  2. Atmospheric convection - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_convection

    Atmospheric convection is the result of a parcel-environment instability (temperature difference layer) in the atmosphere. [ jargon ] Different lapse rates within dry and moist air masses lead to instability.

  3. Convective available potential energy - Wikipedia

    en.wikipedia.org/wiki/Convective_available...

    In meteorology, convective available potential energy (commonly abbreviated as CAPE), [1] is a measure of the capacity of the atmosphere to support upward air movement that can lead to cloud formation and storms.

  4. Convection - Wikipedia

    en.wikipedia.org/wiki/Convection

    Convection is often categorised or described by the main effect causing the convective flow; for example, thermal convection. Convection cannot take place in most solids because neither bulk current flows nor significant diffusion of matter can take place. Granular convection is a similar phenomenon in granular material instead of fluids.

    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 ...

  6. Precipitation types - Wikipedia

    en.wikipedia.org/wiki/Precipitation_types

    A weather front is the boundary of two air masses with different characteristics. Frontal precipitation is the result of frontal systems surrounding extratropical cyclones or lows, which form when warm and tropical air meets cooler, subpolar air. Frontal precipitation typically falls out from nimbostratus clouds. [5]

  7. Atmospheric thermodynamics - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_thermodynamics

    Atmospheric thermodynamics is the study of heat-to-work transformations (and their reverse) that take place in the Earth's atmosphere and manifest as weather or climate. . Atmospheric thermodynamics use the laws of classical thermodynamics, to describe and explain such phenomena as the properties of moist air, the formation of clouds, atmospheric convection, boundary layer meteorology, and ...

  8. 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 ...

    In meteorology, convective ... which makes the air column unstable and encourages convection. There is a major limitation of this measure of stability however, which ...
