Abstract: The Fourier-ray method involves ray tracing in a Fourier-transform domain. The ray solutions are then Fourier synthesized to produce a spatial solution. Here previous steady-state developments of the Fourier-ray method are ...

Abstract: A time-dependent generalization of a Fourier-ray method is presented and tested for fast numerical computation of high-resolution nonhydrostatic mountain-wave fields. The method is used to model mountain waves from Jan ...

Abstract: A Fourier method is combined with a mesoscale model to simulate mountain waves. The mesoscale model describes the nonlinear low-level flow and predicts the emerging wave field above the mountain. This solution serves as ...

Abstract: Fully nonlinear mesoscale model simulations are used to investigate the momentum fluxes of gravity waves that emerge at a ?far-field? height of 6 km from steady unsheared flow over both an axisymmetric and elliptical ...
