In the American West, the base of cumulus clouds can reach, since the combination of a low dew point ( ) and high temperature ( up to ) will yield a very high convective condensation level.

The usual way of finding the LFC is to lift a parcel from a lower level along the dry adiabatic lapse rate until it crosses the mixing ratio line of the parcel : this is the lifted condensation level ( LCL ).
13.
This altitude is known as the lifting condensation level ( LCL ) when mechanical lift is present and the convective condensation level ( CCL ) when mechanical lift is absent, in which case, the parcel must be heated from below to its convective temperature.

If the environmental lapse rate is larger than the dry adiabatic lapse rate, it has a superadiabatic lapse rate, the air is absolutely unstable a parcel of air will gain buoyancy as it rises both below and above the lifting condensation level or convective condensation level.

When there is mechanical lift to saturation, cloud base begins at the lifted condensation level ( LCL ); absent forcing, cloud base begins at the convective condensation level ( CCL ) where heating from below causes spontaneous buoyant lifting to the point of condensation when the convective temperature is reached.

The second favorable feature on the plot is the steep vertical temperature gradient in the lower atmosphere up to the Lifted condensation level ( LCL )-from 26.4 C at the surface ( 989 mb ) to about " 5 C at the LCL, which is about 600 mb.

This work comes from increasing instability in the low levels by raising the temperature or dew point, or by mechanical lift . Without the aid of mechanical forcing, a parcel must reach its convective temperature ( T c ) before moist convection ( cloud ) begins near the convective condensation level ( CCL }, whereas with dynamic lift, cloud base begins near the lifted condensation level ( LCL ).
