PUBLIC ROUTINES

  1. ocean_vert_const_init

    DESCRIPTION
    Initialize the constant vertical diffusivity module.


  2. vert_mix_const

    DESCRIPTION
    This function computes the vertical diffusivity and viscosity. These mixing coefficients are time independent but generally arbitrary functions of space.

&ocean_vert_const_nml

use_this_module
Must be true to use this module. Default is false.
[logical]
kappa_h
The constant vertical diffusivity. Used for cases when wanting a space-time independent diffusivity. The "h" is historical and stands for "heat".
[real, units: m^2/sec]
kappa_m
The constant vertical viscosity. Used for cases when wanting a space-time independent viscosity.
[real, units: m^2/sec]
diff_cbt_limit
The largest allowable vertical diffusivity. Of use for cases where vertically unstable columns are stabilized with a large vertical diffusivity.
[real, units: m^2/sec]

NOTES

The numerical implementation requires no calls to mpp_update_domains.
