An overview of the KIAPS global model development

Abstract:

Korea Institute of Atmospheric Prediction Systems (KIAPS), Seoul, Korea, has embarked a national project in developing a new global forecast system in 2011. The ultimate goal of this 9-year project is to replace the current operational model at Korea Meteorological Administration (KMA), which has been adopted from the United Kingdom’s Meteorological Office’s model. As of July 2015, the initial version of the KIAPS Integrated Model (KIM) system that consists of a spectral element non-hydrostatic dynamical core on a cubed sphere and a physics package from existing models such as the GRIMs, WRF, and GFS, was prepared. This system has been evaluated since July 2015, along with a standard data assimilation of 3-D Var. Early results of KIM system at about 25-km will be demonstrated.
