RISPerformance of Different Soil Model Configurations in Simulating Ground Surface Temperature and Surface Fluxes
Publisher: American Meteorological Society
Abstract: This study compares three modifications to the one-dimensional planetary boundary layer scheme that is implemented in the σ?? hybrid-b version of the Mesoscale Analysis and Prediction System (MAPS) and the Rapid Update ...
Explicit Precipitation-Type Diagnosis from a Model Using a Mixed-Phase Bulk Cloud–Precipitation Microphysics Parameterization
Publisher: American Meteorological Society
Abstract: he Rapid Refresh (RAP) and High-Resolution Rapid Refresh (HRRR), both operational at NOAA?s National Centers for Environmental Prediction (NCEP) use the Thompson et al. mixed-phase bulk cloud microphysics scheme. This ...
Mesoscale Weather Prediction with the RUC Hybrid Isentropic–Terrain-Following Coordinate Model
Publisher: American Meteorological Society
Abstract: A mesoscale atmospheric forecast model configured in a hybrid isentropic?sigma vertical coordinate and used in the NOAA Rapid Update Cycle (RUC) for operational numerical guidance is presented. The RUC model is the only ...
Modifications to the Rapid Update Cycle Land Surface Model (RUC LSM) Available in the Weather Research and Forecasting (WRF) Model
Publisher: American Meteorological Society
Abstract: he land surface model (LSM) described in this manuscript was originally developed as part of the NOAA Rapid Update Cycle (RUC) model development effort; with ongoing modifications, it is now used as an option for the WRF ...
A Performance Comparison between Multiphysics and Stochastic Approaches within a North American RAP Ensemble
Publisher: American Meteorological Society
Abstract: stochastic parameter perturbation (SPP) scheme consisting of spatially and temporally varying perturbations of uncertain parameters in the Grell?Freitas convective scheme and the Mellor?Yamada?Nakanishi?Niino planetary ...
