Short summary
In this study, the orographic gravity wave drag (OGWD) parameterization scheme in the CMA-GFS v4.0 model is revised to account for nonhydrostatic effects (NHE) on the surface momentum flux of subgrid-scale orographic gravity waves. Through a series of 10-day medium-range forecasts, the revised OGWD scheme is shown to significantly improve the simulation of large-scale circulation in the Northern Hemisphere (NH), especially in the high latitudes.
