note, that c the averaging includes zero values on coastal and seafloor grid c points). viscosity on the "u,v-grid" is computed by averaging the c "t-grid" viscosity values onto the "u,v-grid". c c vertical grid: c mixing coefficients get evaluated at the bottom of the lowest c layer, i.e., at depth zw(Nr). these values are only useful when c the model ocean domain does not include the entire ocean down to c the seafloor ("upperocean" setup) and allows flux through the c bottom of the domain. for full-depth runs, these mixing c coefficients are being zeroed out before leaving this subroutine. c c------------------------------------------------------------------------- c global parameters updated by kpp_calc c KPPviscAz - KPP eddy viscosity coefficient (m^2/s) c KPPdiffKzT - KPP diffusion coefficient for temperature (m^2/s) c KPPdiffKzS - KPP diffusion coefficient for salt and tracers (m^2/s) c KPPghat - Nonlocal transport coefficient (s/m^2) c KPPhbl - Boundary layer depth on "t-grid" (m) c KPPfrac - Fraction of short-wave flux penetrating mixing layer c KPPplumefrac- Fraction of saltplume (flux) penetrating mixing layer c-- KPP_CALC computes vertical viscosity and diffusivity for region c (-2:sNx+3,-2:sNy+3) as required by CALC_DIFFUSIVITY and requires c values of uVel, vVel, surfaceForcingU, surfaceForcingV in the c region (-2:sNx+4,-2:sNy+4). c Hence overlap region needs to be set OLx=4, OLy=4. c \ev C !USES: =============================================================== #include "SIZE.h" #include "EEPARAMS.h" #include "PARAMS.h" #include "DYNVARS.h" #include "KPP.h" #include "KPP_PARAMS.h" #include "FFIELDS.h" #include "GRID.h" #include "GAD.h" #ifdef ALLOW_SALT_PLUME # include "SALT_PLUME.h" #endif /* ALLOW_SALT_PLUME */ #ifdef ALLOW_SHELFICE # include "SHELFICE.h" #endif /* ALLOW_SHELFICE */ #ifdef ALLOW_AUTODIFF_TAMC # include "tamc.h" # include "tamc_keys.h" #endif /* ALLOW_AUTODIFF_TAMC */ EXTERNAL DIFFERENT_MULTIPLE LOGICAL DIFFERENT_MULTIPLE C !INPUT PARAMETERS: =================================================== c Routine arguments c bi, bj :: Current tile indices c myTime :: Current time in simulation c myIter :: Current iteration number in simulation c myThid :: My Thread Id. number INTEGER bi, bj _RL myTime INTEGER myIter INTEGER myThid #ifdef ALLOW_KPP C !LOCAL VARIABLES: ==================================================== c Local constants c minusone, p0, p5, p25, p125, p0625 c imin, imax, jmin, jmax - array computation indices _RL minusone parameter( minusone=-1.0) _RL p0 , p5 , p25 , p125 , p0625 parameter( p0=0.0, p5=0.5, p25=0.25, p125=0.125, p0625=0.0625 ) integer imin ,imax ,jmin ,jmax parameter(imin=2-OLx,imax=sNx+OLx-1,jmin=2-OLy,jmax=sNy+OLy-1) c Local arrays and variables c work?
