DOI: 10.1002/qj.3828
Abstract: The parameterization of orographic gravity wave drag (OGWD) in the Weather Research and Forecasting model is extended by including the second‐order Wentzel‐Kramers‐Brillouin (WKB) corrections to the surface wave momentum flux (SWMF) caused by wind profile… read more here.

DOI: 10.1029/2021gl093305
Abstract: In the extratropical atmosphere, Rossby waves (RWs) and internal gravity waves (GWs) propagating from the troposphere mediate a coupling with the middle atmosphere by influencing the dynamics therein. In state‐of‐the‐art chemistry‐climate models (CCMs), RW effects… read more here.
