Unification of cloud macro- and micro-physics scheme in global climate models A kinetic condensation method (KCM) was developed to remove the saturation adjustment assumption and resolve the condensation process in the grid-scale cloud macrophysics scheme to build an integrated stratiform cloud physics scheme for global climate models. By applying a saturation prediction equation with calculations based on cloud hydrometeor properties, supersaturation or undersaturation can be resolved within the macrophysics scheme. This treatment provides the basis for condensation calculation. It allows the Wegener–Bergeron–Findeisen process to be resolved explicitly to render a realistic liquid–ice partition in mixed-phase clouds. KCM provides a theoretical-based way to determine the cloud liquid and ice partition rather than linearly depending on temperature. Reference: Pi and Chen, 2021
