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

   This makes moist air generally less stable than dry air (see convective available potential energy [CAPE]). The dry adiabatic lapse rate (for unsaturated air) is 3 °C (5.4 °F) per 1,000 vertical feet (300 m). The moist adiabatic lapse rate varies from 1.1 to 2.8 °C (2.0 to 5.0 °F) per 1,000 vertical feet (300 m).

4. Stable and unstable stratification - Wikipedia

   en.wikipedia.org/wiki/Stable_and_unstable...

   Stable stratification of fluids occurs when each layer is less dense than the one below it. Unstable stratification is when each layer is denser than the one below it. Buoyancy forces tend to preserve stable stratification; the higher layers float on the lower ones. In unstable stratification, on the other hand, buoyancy forces cause convection ...

5. Lifted index - Wikipedia

   en.wikipedia.org/wiki/Lifted_index

   Unstable areas are in yellow (slightly) and red (highly) while the stable zone is in blue. The lifted index ( LI ) is the temperature difference between the environment Te(p) and an air parcel lifted adiabatically Tp(p) at a given pressure height in the troposphere (lowest layer where most weather occurs) of the atmosphere , usually 500 hPa ( mb ).

6. Free convective layer - Wikipedia

   en.wikipedia.org/wiki/Free_convective_layer

   It is a layer in which rising air can experience positive buoyancy (PBE) so that deep, moist convection (DMC) can occur. On an atmospheric sounding, it is the layer between the level of free convection (LFC) and the equilibrium level (EL). The FCL is important to a variety of convective processes and to severe thunderstorm forecasting.
