Generalized Quasi-Geostrophy for Moist Spatially Anisotropic Atmospheric Flows with Phase Changes.

Traditionally, the simulation of precipitating convection use a non-Boussinesq dynamical core such as the anelastic equations, and would incorporate water substance in all of its phases: vapour (cloud and rain), liquid and ice. Furthermore, the liquid water phase would be separated into cloud water (small droplets suspended in air) and rain water (larger droplets that fall). Depending on environmental conditions, the moist convection may organize itself on multiple length and time scales. One of the minimal representations of water substance and dynamics that still reproduces the basic regimes of turbulent convection regime is the Fast Autoconversion and Rapid Evaporation (FARE) model, which can reproduces unorganized (“scattered”) or organized convection, such as tilted rain water profiles and low-altitude cold pools ( https://doi:10.1017/jfm.2012.597 ).
