Limit of convection

limit of convection

(Abbreviated LOC). The level of neutral buoyancy for a saturated rising air parcel.

If a cloudy air parcel is rising under its own buoyancy, then the parcel can rise to the altitude where the virtual potential temperatures of the parcel and environment are equal. Neglecting inertial overshoot, the LOC would mark the top of convective clouds.
Compare lifting condensation level, level of free convection.
