  2. Atmospheric instability - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_instability

    It is a form of fluid instability found in thermally stratified atmospheres in which a colder fluid overlies a warmer one. When an air mass is unstable, the element of the air mass that is displaced upwards is accelerated by the pressure differential between the displaced air and the ambient air at the (higher) altitude to which it was displaced.

  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. Convective available potential energy - Wikipedia

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

    A good example of convective instability can be found in our own atmosphere. If dry mid-level air is drawn over very warm, moist air in the lower troposphere, a hydrolapse (an area of rapidly decreasing dew point temperatures with height) results in the region where the moist boundary layer and mid-level air meet. As daytime heating increases ...

  5. Air mass - Wikipedia

    en.wikipedia.org/wiki/Air_mass

    Monsoon air masses are moist and unstable. Superior air masses are dry, and rarely reach the ground. They normally reside over maritime tropical air masses, forming a warmer and drier layer over the more moderate moist air mass below, forming what is known as a trade wind inversion over the maritime tropical air mass.

  6. Inversion (meteorology) - Wikipedia

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

    A warmer air mass moving over a cooler one can "shut off" any convection which may be present in the cooler air mass: this is known as a capping inversion. However, if this cap is broken, either by extreme convection overcoming the cap or by the lifting effect of a front or a mountain range, the sudden release of bottled-up convective energy ...

  7. Conditional symmetric instability - Wikipedia

    Weather radar loop showing intense snow bands (lighter color) due to CSI ahead of a warm front.. Conditional symmetric instability, or CSI, is a form of convective instability in a fluid subject to temperature differences in a uniform rotation frame of reference while it is thermally stable in the vertical and dynamically in the horizontal (inertial stability).

  9. Convective overshoot - Wikipedia

    en.wikipedia.org/wiki/Convective_overshoot

    Convective overshoot also occurs at the boundaries of convective zones in stars.An example of this is at the base of the convection zone in the solar interior.The heat of the Sun's thermonuclear fusion is carried outward by radiation in the deep interior radiation zone and by convective circulation in the outer convection zone, but cool sinking material from the surface penetrates further into ...
