Physical Parameterization in Next-Generation NWP Models
WHAT: Scientists from Korea, Japan, and the United States discuss recent developments in the parameterizations of physical processes in nextgeneration, high-resolution numerical weather prediction models WHEN: 17–18 May 2004 WHERE: Yonsei University, Seoul, Korea he Second International Workshop on NextGeneration Numerical Weather Prediction (NWP) Models1 met to discuss the impact of recent developments in modeling for next-generation, high-resolution NWP models, and to exchange ideas for improving the prediction of high-impact weather. In 1999, the Laboratory for Atmospheric Modeling Research (LAMOR) of Yonsei University (YSU) embarked on a national project developing a next-generation NWP model focusing on the parameterization of physical processes in high-resolution models (see information online at http://lamor.yonsei.ac.kr). The ultimate goal of the project is in line with that of the Weather Research and Forecast (WRF) model initiative (see information online at http://wrf-model. org), both of which are to develop a state-of-the-art mesoscale model that is suitable for grid spacing in the range of 1–30 km. The director of LAMOR, Professor Tae-Young Lee, told participants that the focus of this workshop was to discuss the progress in our understanding of the physical parameterizations and the outcome of collaboration between the LAMOR and U.S. groups for the past three years. Major outcomes of collaborations include the Yonsei University PBL (YSUPBL) and WRF single-moment microphysics (WSM) schemes implemented in the WRF model.
