Dr. habil. Achim Wirth, Laboratoire des Écoulements Géophysiques et Industriels (LEGI) , Grenoble (France): "Inertia - gravity waves generated by near balanced flow in 2-layer shallow water turbulence on the ß-plane"

11:00 h, Hörsaal, Düsternbrooker Weg 20

 

Abstract:

Using a fine resolution numerical model (4000 2 × 2 grid-points) of the two-layer shallow-water equations of the mid-latitude β-plane dynamics, it is shown that there is no sudden breakdown of balance in the turbulent enstrophy cascade but a faint and continuous emission of inertia–gravity waves. The wave energy accumulates in the equator-ward region of the domain due to the Coriolis parameter depending on the latitude and dispersion relation of inertia–gravity waves.
