ray_fast
RayleighDamping
Apply Rayleigh damping (for tau > 0).
Namelist
- tau [Float]: time scale (in days) for Rayleigh friction applied to horizontal and vertical winds; lost kinetic energy is converted to heat, except on nested grids.
- rf_cutoff [Float]: pressure below which no Rayleigh damping is applied if tau > 0.
Fortran name: ray_fast.
