I implemented and evaluated a new parameterization scheme for stratiform cloud microphysics and precipitation within the regional climate model RegCM4. This new parameterization is based on a multiple phase one-moment cloud microphysics scheme built upon the implicit numerical framework recently developed and implemented into the ECMWF operational forecasting model. The parameterization solves 5 prognostic equations for water vapour, cloud liquid water, rain, cloud ice and snow mixing ratios. Compared to the pre-existing scheme, it allows a proper treatment of mixed-phase clouds and a more physically realistic representation of cloud miscrophysics and precipitation. Various fields from a 10-yr-long integration of RegCM4 run in tropical band mode with the new scheme are compared with their counterparts using the previous cloud scheme as well as with satellite observations through the use of the COSP simulator. The new microphysics parameterization yields an improved simulation of cloud fields and in particular it removes the overestimation of upper level clouds characteristics of the previous scheme, increasing the agreement with observations and leading to an amelioration of a long-standing problem in the RegCM system. The vertical cloud profile produced by the new scheme leads to a considerably improvement of the representation of the longwave and shortwave components of the cloud radiative forcing.
