In this project a scale analysis of the full equations for the moist atmosphere including bulk representations of phase changes and precipitation will be performed. Using the method of multiple scales asymptotics, reduced sets of equations for simplified prototype stratiform- and cumulus clouds will be derived. These reduced equations can be used (i) as a guideline in formulating subgrid models of cloud formation and precipitation in large scale numerical weather prediction models, and (ii) to define analytically motivated test problems for computational codes that solve the full governing equations with bulk microphysics parameterizations.
