With the help of these lines, parameters such as cloud condensation level, level of free convection, onset of cloud formation.

Finally, the LCL can also be considered in relation to the level of free convection (LFC).

In most cases, when CIN exists, it covers a layer from the ground to the level of free convection (LFC).

On an atmospheric sounding, it is the layer between the level of free convection (LFC) and the equilibrium level (EL).

Level of free convection (LFC) (Glossary of Meteorology)

Very unstable air can reach the level of free convection (LFC) and thus rise to great heights condensing large quantities of water and so forming showers or even thunderstorms.

Generic CAPE is calculated by integrating vertically the local buoyancy of a parcel from the level of free convection (LFC) to the equilibrium level (EL):

When a layer of CIN is present, the layer must be eroded by surface heating or mechanical lifting, so that convective boundary layer parcels may reach their level of free convection (LFC).

The level of free convection (LFC) is the altitude in the atmosphere where the temperature of the environment decreases faster than the moist adiabatic lapse rate of a saturated air parcel at the same level.

Convective inhibition (CIN or CINH) is a numerical measure in meteorology that indicates the amount of energy that will prevent an air parcel from rising from the surface to the level of free convection.

Where and are, respectively, the heights of the levels of free convection and equilibrium (neutral buoyancy), is the virtual temperature of the specific parcel, is the virtual temperature of the environment, and is the acceleration due to gravity.
