 ugwpv1_gsldrag.F90
 This introduces two gravity wave drag schemes ugwpv1/CIRES and GSL/drag_suite.F90 under "ugwpv1_gsldrag" suite: 1) The "V1 CIRES UGWP" scheme as tested in the FV3GFSv16-127L atmosphere model and workflow, which includes: a) the orograhic gravity wave drag, flow blocking scheme and TOFD (Beljaars et al, 2004). b) the v1 CIRE ugwp non-stationary GW scheme, new revision that generate realistic climate of FV3GFS-127L in the strato-mesosphere in the multi-year simulations (Annual cycles, SAO and QBO in th tropical dynamics). 2) The GSL orographic drag suite (drag_suite.F90), as implmeneted in the RAP/HRRR, which includes: a) large-scale gravity wave drag and low-level flow blocking – active at horizontal scales down to ~5km (Kim and Arakawa, 1995 [107]; Kim and Doyle, 2005 [108]) b) small-scale gravity wave drag scheme – active typically in stable PBL at horizontal grid resolutions down to ~1km (Steeneveld et al, 2008 [188]; Tsiringakis et al, 2017 [194]) c) turbulent orographic form drag – active at horizontal grid ersolutions down to ~1km (Beljaars et al, 2004 [14]) See Valery Yudin's presentation at 2020 UFS User's meeting (Jul 2020): 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.
