Maximum parcel level

The maximum parcel level (MPL) is the highest level in the atmosphere that a moist convectively rising air parcel will reach after ascending through the free convective layer (FCL) and reaching the equilibrium level (EL) where it loses buoyancy. At the EL, the temperature of a parcel becomes cooler than that of the environment but due to momentum a parcel continues rising past this level (which is near the tropopause and approximates the altitude where the anvil forms) and ceases at the MPL (visually represented by the overshooting top).
