Numerical weather prediction and climate models have large uncertainties associated with representing clouds and microphysical properties and processes, which involve a large amount of hydrometeor of various types in much smaller scale than grid size in theses numerical models. Development of particle-based detailed cloud models has the potential to improve the understanding and representation of microphysical properties and processes in microphysical schemes used in the numerical weather prediction and climate models in a profound way. To that end, a new cloud microphysics model is presented. The cloud particle model (CPM) attempts to capture the evolution of every particle by accounting for various microphysical processes, including condensational growth, evaporation, collision-coalescence-breakup events, and sedimentation in box model or 1D rain shaft model settings. In this talk, an initial comparison between the 1D rain shaft model output from CPM and radar observations of a warm rain event observed in Seoul metropolitan area during an intensive observation period of summer monsoons in X-Net field campaign in South Korea is presented to understand the model’s current strengths and weaknesses.
