This study examines gravity waves that develop at the boundary-layer capping inversion in the lee of a mountain ridge.By comparing different linear wave theories, we show that lee waves that form under these conditions are most accurately described as forced interfacial waves.Perturbations in this type of flow can be studied with a linear two-dimen
