KIM’s dynamic core consists of non-hydrostatic governing equation set on cubed sphere and spectral element method. Physics packages are developed based on Weather Research and Forecasting (WRF) model and Global-Regional Integrated Model system (GRIMS) physics packages. KIAPS scientists have implemented several vital aspects of physics parameterizations such as non-orographic gravity wave drag, gray-zone convection, top-down mixing method in PBL, prognostic cloudiness, and radiation-cloud interactions. The KIM is a self-cycled 3DVAR data assimilation system with its own data acquisition and quality control. In this talk, the performance of the KIM will be presented on top of the brief overview of KIM in terms of dynamics, physics, and data assimilation system.
