Equilibrium level

Source: Wikipedia, the free encyclopedia.

In

air is at the same temperature as its environment.

This means that unstable air is now stable when it reaches the equilibrium level and

updraft is finally cut off, except in the case of overshooting tops where it continues rising to the maximum parcel level (MPL) due to momentum. More precisely, the cumulonimbus will stop rising around a few kilometres prior to reaching the level of neutral buoyancy and on average anvil glaciation occurs at a higher altitude over land than over sea (despite little difference in LNB from land to sea).[1]
