Status and Plan of Global NWP Model at Kiaps

Abstract:

Korea Institute of Atmospheric Prediction Systems (KIAPS), Seoul, Korea,

 has embarked a national project in developing a new global forecast system from 2011 to 2019. The ultimate goal of this project is to replace the current operational model at Korea Meteorological Administration (KMS), which has been adopted from the United Kingdom’s Meteorological Office’s model. As of July 2014, the initial version of the model system that consists of a spectral element dynamical core on a cubed sphere and a standard physics package from existing models such as the GRIMs, WRF, and GFS. This system is scheduled to be run daily at the later 2014, with a standard data assimilation of 3-D Var. The target resolution in 2020 is a 10-km grid. The advanced model system, which is scheduled to be tested around 2016, includes dynamical core, physical parameterizations, and data assimilation. The GRIMs and WRF models are used as tools in developing/revising advanced physics schemes, in addition to the usage of reference models. The data assimilation is to adapt the ensemble Kalman filer technology, along with the variational method. A more accurate and efficient dynamical core could be tested out.
