Dr. Songyou Hong received the Ph. D at Seoul National University on the subject of numerical simulation of a heavy rainfall using the MM4 in 1992 summer. He then continued modeling research in areas of physical parameterizations of the NCEP GFS and RSM since 1993 summer, and lead the development of MRF PBL (Hong and Pan, 1996, MWR) and several physics algorithms. After moving to Yonsei University, Seoul, Korea, in 2000 summer, Dr. Hong has lead the development of the YSU PBL (Hong et al. 2006, MWR) and WSM (Hong et al. 2004, MWR) and WDM (Lim and Hong 2010, MWR) microphysics schemes in the WRF model. Also, he created the Global/Regional Integrated Modeling system (GRIMs; Hong et al. 2013, Asia-Pac. J. Atmos. Sci.), for use in numerical weather prediction, seasonal simulations, and climate researches from global to regional scales. Since 2014 spring, Dr. Hong began a new career as the director of the Korea Institute of Atmospheric Prediction Systems (KIAPS). The Korean Integrated Model (KIM, Hong et al. 2018, Asia-Pac. J. Atmos. Sci.) for global weather forecasting has been operational at the Korea Meteorological Administration (KMA) since April 2020. He published about 150 peer-reviewed papers and the number of citations exceeds 20,000.
