bfb_initialization module reference¶

Initialization of the boundary-forced-basing configuration.

Functions/Subroutines¶

`bfb_set_coord()`	This subroutine specifies the vertical coordinate in terms of temperature at the surface and at the bottom.
`bfb_initialize_sponges_southonly()`	This subroutine sets up the sponges for the southern boundary of the domain.

Detailed Description¶

Initialization of the boundary-forced-basing configuration.

Function/Subroutine Documentation¶

subroutine bfb_initialization/bfb_set_coord(Rlay, g_prime, GV, US, param_file)¶

This subroutine specifies the vertical coordinate in terms of temperature at the surface and at the bottom. This case is set up in such a way that the temperature of the topmost layer is equal to the SST at the southern edge of the domain. The temperatures are then converted to densities of the top and bottom layers and linearly interpolated for the intermediate layers.

Parameters:

gv :: [in] The ocean’s vertical grid structure
rlay :: [out] Layer potential density [R ~> kg m-3].
g_prime :: [out] The reduced gravity at each interface [L2 Z-1 T-2 ~> m s-2].
us :: [in] A dimensional unit scaling type
param_file :: [in] A structure to parse for run-time parameters

mom_coord_initialization::mom_initialize_coord

subroutine bfb_initialization/bfb_initialize_sponges_southonly(G, GV, US, use_temperature, tv, depth_tot, param_file, CSp, h)¶

This subroutine sets up the sponges for the southern boundary of the domain. Maximum damping occurs within 2 degrees lat of the boundary. The damping linearly decreases northward over the next 2 degrees.

Parameters:

g :: [in] The ocean’s grid structure
gv :: [in] The ocean’s vertical grid structure.
us :: [in] A dimensional unit scaling type
use_temperature :: [in] If true, temperature and salinity are used as state variables.
tv :: [in] A structure pointing to various thermodynamic variables
depth_tot :: [in] The nominal total depth of the ocean [Z ~> m]
param_file :: [in] A structure to parse for run-time parameters
csp :: A pointer to the sponge control structure
h :: [in] Layer thicknesses [H ~> m or kg m-2]
