| Abstract: | Summary A new entrainment/detrainment formulation in the Tiedtke’s mass flux cumulus parameterization is discussed here. Apart from
validating it with observations both in one and three dimensional cases, it is also evaluated in the light of the results
from the original Tiedtke scheme and another mass flux scheme due to Emanuel. The proposed analytical profiles of entrainment
and detrainment, easier to implement in any mass flux scheme, give reasonable results in GCM experiments. |
