Model Grid (Horizontal grid for RSM and ROMS are identical.)
RSM: (Nx,Ny,Nz)=(321,282,28)
Longitudes: 29.76E-111.96E, dx= 0.26,
Latitudes: 29.775S-38.469N; dy=varying: 0.226 at 29.775S, 0.26 at EQ, 0.203 at 38.469
Vertical: 28 sigma layers.
Pressure level outputs: 12 (1000, 925, 850, 700, 600, 500, 400 300 250 200 150 100mb)
ROMS:
Horizontal: identical to RSM
Vertical: 20 stretched sigma layer.
Stretching parameters: thetas: 6.5, thetab: 0
Coupling: Daily
RSM -> ROMS
net heat flux (shflux)
swrad (net shortwave radiation)
swflux (E-P)
sustr (u-wind stress), svstr(v-wind stress)
ROMS -> RSM: SST
Fluxes are extracted directly from RSM’s outputs computed from its PBL physics.
No TOGA-COARE bulk parameterization.
No interpolation of flux except for regridding of sustr and svstr to u-,v-grid for ROMS.
Ocean current was not included in the stress computation.
Total heat flux was imposed, not the individual components
