level of free convection"(Abbreviated LFC.) The level at which a parcel of air lifted dry-adiabatically until saturated and saturation-adiabatically thereafter would first become warmer than its surroundings in a conditionally unstable atmosphere.
LEVEL OF FREE CONVECTION (LFC) The level at which a parcel of saturated air becomes warmer than the surrounding air and begins to rise freely. This occurs most readily in a conditionally unstable atmosphere.
LFC - Level of Free Convection. The level at which lifted air becomes unstable and hence rises on its own. Mamma - Pouch-like clouds, usually found beneath the anvil of a thunderstorm.
LFC - Acronym for Level of Free Convection. This is the altitude where a rising parcel of air enters the region of free convection (usually above the cap and boundary layer). See also FREE CONVECTION.
Some values that can be determined are the Convective Condensation Level (CCL), the Lifting Condensation Level (LCL), and the Level of Free Convection (LFC).
Equilibrium Level(EL) - On a sounding, the level above the level of free convection (LFC) at which the temperature of a rising air parcel again equals the temperature of the environment.
On a thermodynamic diagram this is called positive area, and can be seen as the region between the lifted parcel process curve and the environmental sounding, from the parcel's level of free convection to its level of neutral buoyancy.
A region of negative buoyancy below an existing level of free convection (LFC) where energy must be supplied to the parcel to maintain its ascent.
(EL) - On a sounding, the level above the level of free convection (LFC) at which the temperature of a rising air parcel again equals the temperature of the environment.
Motion caused only by density differences in a fluid. See also Level of Free Convection Freeze The phase change of a liquid to solid.
Convective inhibition (CIN or CINH) is a meteorlogic parameter that measures the amount of energy that will prevent an air parcel from rising from the surface to the level of free convection. Conceptually, it is the opposite of CAPE. [edit] ...
