  2. Squall line - Wikipedia

    en.wikipedia.org/wiki/Squall_line

    Squall line. A squall line, or more accurately a quasi-linear convective system (QLCS), is a line of thunderstorms, often forming along or ahead of a cold front. In the early 20th century, the term was used as a synonym for cold front (which often are accompanied by abrupt and gusty wind shifts). Linear thunderstorm structures often contain ...

  3. Vertical draft - Wikipedia

    en.wikipedia.org/wiki/Vertical_draft

    Vertical drafts, known as updrafts or downdrafts, are localized regions of warm or cool air that move vertically. A mass of warm air will typically be less dense than the surrounding region, and so will rise until it reaches air that is either warmer or less dense than itself. The converse will occur for a mass of cool air, and is known as ...

  4. Mesoscale convective system - Wikipedia

    en.wikipedia.org/wiki/Mesoscale_convective_system

    A mesoscale convective system (MCS) is a complex of thunderstorms that becomes organized on a scale larger than the individual thunderstorms but smaller than extratropical cyclones, and normally persists for several hours or more. A mesoscale convective system's overall cloud and precipitation pattern may be round or linear in shape, and ...

  5. Cloud physics - Wikipedia

    en.wikipedia.org/wiki/Cloud_physics

    v. t. e. Cloud physics is the study of the physical processes that lead to the formation, growth and precipitation of atmospheric clouds. These aerosols are found in the troposphere, stratosphere, and mesosphere, which collectively make up the greatest part of the homosphere. Clouds consist of microscopic droplets of liquid water (warm clouds ...

  6. Multicellular thunderstorm - Wikipedia

    en.wikipedia.org/wiki/Multicellular_thunderstorm

    A multicellular thunderstorm cluster is a thunderstorm that is composed of multiple convective cells, each being at a different stage in the life cycle of a thunderstorm. It appears as several anvils clustered together. A cell is an updraft/downdraft couplet. These different cells will dissipate as new cells form and continue the life of the ...

    The resulting thunderstorms are “very dangerous” for air travel, Struckmann said. This is due to the “severe turbulence caused by updrafts, downdrafts, winds and hail.”

  9. Cumulonimbus cloud - Wikipedia

    en.wikipedia.org/wiki/Cumulonimbus_cloud

    Cumulonimbus (from Latin cumulus 'swell' and nimbus 'cloud') is a dense, towering, vertical cloud, [1] typically forming from water vapor condensing in the lower troposphere that builds upward carried by powerful buoyant air currents. Above the lower portions of the cumulonimbus the water vapor becomes ice crystals, such as snow and graupel ...
