The objective of this
study is to describe the short-range forecast system of the Korea Air Force
(KAF). The KAF weather prediction model system, based on the Weather Research
and Forecasting (WRF) model (i.e., the KAF- WRF), is configured with a parent
domain overs East Asia and two nested domains with the finest horizontal grid
size of 2 km. The global model output from the National Centers for
Environmental Prediction (NCEP) Global Forecast System (GFS) had been used to
provide the large-scale forcing for the outer domain of the KAF-WRF at an 18-km
grid. As of March 2012, the boundary conditions for the KAF-WRF was replaced by
the forecasts with the Global/Regional Integrated Model system (GRIMs) at the
horizontal grid spacing of approximately 25-km. The evaluation of the KAF-WRF
forecasts will be presented with the focus on the influence of the global model
forecasts providing the large-scale forcing.
