Detailed Description

See Valery Yudin's presentation at 2017 NGGPS PI meeting: Gravity waves (GWs): Mesoscale GWs transport momentum, energy (heat) , and create eddy mixing in the whole atmosphere domain; Breaking and dissipating GWs deposit: (a) momentum; (b) heat (energy); and create (c) turbulent mixing of momentum, heat, and tracers To properly incorporate GW effects (a-c) unresolved by DYCOREs we need GW physics "Unified": a) all GW effects due to both dissipation/breaking; b) identical GW solvers for all GW sources; c) ability to replace solvers. Unified Formalism:

  • GW Sources: Stochastic and physics based mechanisms for GW-excitations in the lower atmosphere, calibrated by the high-res analyses/forecasts, and observations (3 types of GW sources: orography, convection, fronts/jets).
  • GW Propagation: Unified solver for "propagation, dissipation and breaking" excited from all type of GW sources.
  • GW Effects: Unified representation of GW impacts on the "resolved" flow for all sources (energy-balanced schemes for momentum, heat and mixing). https://www.weather.gov/media/sti/nggps/Presentations%202017/02%20NGGPS_VYUDIN_2017_.pdf
