  2. Atmospheric instability - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_instability

    Atmospheric instability is a condition where the Earth's atmosphere is considered to be unstable and as a result local weather is highly variable through distance and time. [ clarification needed ] [ 1 ] Atmospheric instability encourages vertical motion, which is directly correlated to different types of weather systems and their severity.

  3. Convective instability - Wikipedia

    en.wikipedia.org/wiki/Convective_instability

    Instability results from difference between the adiabatic lapse rate of an air mass and the ambient lapse rate in the atmosphere. [2] If the adiabatic lapse rate is lower than the ambient lapse rate, an air mass displaced upward cools less rapidly than the air in which it is moving. Hence, such an air mass becomes warmer relative to the ...

  4. Planetary boundary layer - Wikipedia

    en.wikipedia.org/wiki/Planetary_boundary_layer

    In meteorology, the planetary boundary layer (PBL), also known as the atmospheric boundary layer (ABL) or peplosphere, is the lowest part of the atmosphere and its behaviour is directly influenced by its contact with a planetary surface. [1] On Earth it usually responds to changes in surface radiative forcing in an hour or less.

  5. Convergence zone - Wikipedia

    en.wikipedia.org/wiki/Convergence_zone

    A convergence zone in meteorology is a region in the atmosphere where two prevailing flows meet and interact, usually resulting in distinctive weather conditions. [1] This causes a mass accumulation that eventually leads to a vertical movement and to the formation of clouds and precipitation. [1]

  6. 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 ...

  7. Weather front - Wikipedia

    en.wikipedia.org/wiki/Weather_front

    S for s uperior air (dry air formed by significant upward lift in the atmosphere). The third letter designates the stability of the atmosphere; it is labeled: k if the air mass is c older (“ k older”) than the ground below it. w if the air mass is w armer than the ground below it.

    The strong system is bringing a significant amount of atmospheric instability to the region. Extreme amounts of rainfall are also being enhanced with moisture from the Mediterranean Sea and ...

  9. Tectonic–climatic interaction - Wikipedia

    en.wikipedia.org/wiki/Tectonic–climatic...

    Tectonic–climatic interaction is the interrelationship between tectonic processes and the climate system. The tectonic processes in question include orogenesis, volcanism, and erosion, while relevant climatic processes include atmospheric circulation, orographic lift, monsoon circulation and the rain shadow effect.
