In Gregory scheme, not only the importance of the moist static energy is taken into account, but also the common difficulty of the moist convective adjustment scheme, the determination of the temperature profile, is obviated. At the same time, it can give the vertical profile of the apparent heat source Q〓 and apparent moisture sink Q〓. Gregory scheme has the clear physical image that includes the cumulus updrafts, cumulus downdrafts,cumulus induced subsidence in the environmental air, entrainment,detrainment and evaporation. In addition, the interaction between the cumulus and the environment is described by one-dimensional bulk model. It is simpler than the Arakawa-Schubert scheme and has no difficult to decide the spectrum of clouds accurately.It is propitious to operational use because of its simple calculation. Finally, Gregory scheme is not only suitable for moist convection of all types, but also for dry convection.
