3D Baroclinic spectral solver
The 3D baroclinic spectral solver is now operational! It is based on a fully implicit 3D semi-linearized wave equation, and thanks to the now-a-day available optimized linear system solvers, it is an extremely cost-efficient way to model internal waves. On caption, an academic internal tide illustration (amplitude of levels displacements of M2 tide in meters, uniform N=1.e-02; x-axis units in km), where the internal tide regime is clearly dominated by the first and second baroclinic vertical modes.
