DOI: 10.1002/qj.2915
Abstract: This study presents an analytical model for the amplitude of lee waves on the boundary-layer inversion in two-dimensional flow. Previous linear lee wave models, in which the amplitude depends on the power spectrum of topography,… read more here.

Abstract: Mountain wave drag is evaluated explicitly using linear theory and verified against numerical simulations for the flow of idealized two-layer atmospheres with piecewise-constant stratification over an axisymmetric mountain. Static stability is either higher in the… read more here.

Abstract: This paper presents experimental and theoretical results on the internal waves emitted by a bluff body moving horizontally in a linearly stratified fluid. Three different bluff bodies (a sphere, a spheroid and a cylinder) have… read more here.

Abstract: Abstract Lee waves generated by stratified flow over rough bottom topography in the ocean extract momentum and energy from the geostrophic flow, causing drag and enhancing turbulence and mixing in the interior ocean when they… read more here.

DOI: 10.1175/jpo-d-19-0052.1
Abstract: Microstructure measurements in Drake Passage and on the flanks of Kerguelen Plateau find turbulent dissipation ratesεon average factors of 2–3 smaller than linear lee-wave generation predictions, as well as a factor of 3 smaller than… read more here.
