abstract: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.
Supposing that the levelof freeconvection is equalto the cloudbottomlevel, we considered the pullingeffectsofsimulatedsub-gridscaleprecipitation, which is underclouds.
