Crucial Role of Obliquely Propagating Gravity Waves in the Quasi-Biennial Oscillation Dynamics
Young-Ha Kim, Georg S. Voelker, Gergely Bölöni +2
In climate modelling, the reality of simulated flows in the middle atmosphere is largely affected by the model's representation of gravity wave processes that are unresolved, while…

A Constrained Spectral Approximation of Subgrid-Scale Orography on Unstructured Grids
Ray Chew, Stamen Dolaptchiev, Maja-Sophie Wedel +1
The representation of subgrid-scale orography is a challenge in the physical parameterization of orographic gravity-wave sources in weather forecasting. A significant hurdle is enc…

MS-GWaM: A 3-dimensional transient gravity wave parametrization for atmospheric models
Georg S. Voelker, Gergely Bölöni, Young-Ha Kim +2
Parametrizations for internal gravity waves in atmospheric models are traditionally subject to a number of simplifications. Most notably, they rely on both neglecting wave propagat…
