A two-moment bulk stratiform microphysics scheme, including recently developed physically-based droplet activation/ice nucleation parameterizations has been implemented into the Grid-point Atmospheric Model of IAP LASG (GAMIL) as an effort to enhance the model's capability to simulate aerosol indirect effects. Unlike the previous one-moment cloud microphysics scheme, the new scheme produces a reasonable representation of cloud particle size and number concentration.

1.IntroductionAlthough the importance of clouds in climate sys-tem is well known(Arakawa,2004),cloud representa-tion in general circulation models(GCMs)remains achallenge due to the vast range of temporal and spatialscales in cloud processes(Iacono et al.
