The study analyzes gravity waves in a high-resolution simulation. A unique methodology is applied to compute three-dimensional gravity wave spectra while keeping the data on the original triangular model grid and using linear wave theory. The results show the structure of gravity waves that would remain unresolved by a model with lower horizontal resolution. It is shown that the spectra can be highly simplified, which can help constructing precise but efficient gravity wave parametrisation.
