GFS Rayleigh Damping Calculation


This is the Rayleigh friction calculation with total energy conservation.
Role of Rayleigh friction, it attempts to resolve two issues:

  • The top lid model effects, sponge layer to suppress resolved wave reflections and extra-heating
  • The winter-summer zonal wind drag in the strato-mesosphere
