Medium-Range Forecasts with the Korean Integrated Model (KIM) System
Abstract
The Korea Institute of Atmospheric Prediction Systems (KIAPS) began a national project to develop a new global atmos- pheric model system in 2011. The ultimate goal of this 9-year project is to replace the current operational model at the Korea Meteor- ological Administration (KMA), which was adopted from the United Kingdom's Meteorological Office's unified model (UM) in 2010. The 12-km Korean Integrated Model (KIM) system, consisting of a spectral-element non-hydrostatic dynamical core on a cubed sphere grid and a state-of-the-art physics parameterization package, has been launched in a real-time forecast framework, with initial con- ditions obtained via the advanced hybrid four-dimensional ensemble variational data assimilation (4DEnVar) over its native grid. A development strategy for KIM and the evolution of its performance in medium-range forecasts toward a world-class global forecast system are described. Outstanding issues in KIM 3.1 as of February 2018 are discussed, along with a future plan for operational deploy- ment in 2020.
