Elastic Non-Uniform FFT (ENUFFT) spectral reconstruction of irregularly sampled orography on unstructured grids
Tridib Banerjee, Felix Jochum, Ulrich Achatz
Subgrid-scale orography remains a leading source of uncertainty in numerical modeling because terrain spectra must be recovered from irregularly sampled elevation data and then red…

The impact of transience in the interaction between orographic gravity waves and mean flow
Felix Jochum, Ray Chew, François Lott +3
A Lagrangian gravity-wave parameterization (MS-GWaM, Multi-Scale Gravity-Wave Model) that allows for fully transient wave-mean-flow interaction and horizontal propagation is applie…
