A Description of The MYNN-EDMF Scheme and The Coupling To Other Components In WRF–ARW


The Mellor–Yamada–Nakanishi–Niino (MYNN) (Nakanishi and Niino 2001, 2004, 2006, and 2009) scheme was first integrated into the Advanced Research version of the Weather Research and Forecasting Model (WRF-ARW) version 3.1 (Skamarock et al. 2008) by Mariusz Pagowski of the National Oceanic and Atmospheric Administration (NOAA) Global Systems Division (GSD). The purpose of this addition was to introduce an alternative turbulent kinetic energy (TKE)-based planetary boundary layer (PBL) scheme which could serve as a candidate PBL parameterization for NOAA’s operational Rapid Refresh (RAP; Benjamin et al. 2016) and High-Resolution Rapid Refresh (HRRR) forecast systems.
