| Outline of Final Research Achievements |
The super-droplet method (SDM) is a particle-based and probabilistic numerical scheme, which enables the accurate simulation of cloud microphysics with less demand on computation. In the SDM, the time evolution of particles is calculated explicitly by solving the fundamental governing equations. In this project, anticipating the advent of exascale computing era, we extended and advanced the SDM to construct a more sophisticated cloud resolving model. The new model can explicitly predict the time evolution of the diverse morphology of ice particles in deep convection. We also conducted several numerical studies on warm clouds. In particular, we elucidated for the first time that grid resolution less than about 10m is necessary to obtain an accurate numerical solution of trade-wind shallow maritime cumuli field. We also examined the possibility to accelerate the calculation, with some attention to cloud-turbulence interaction.
