ocean_gm_config_t Derived Type

type, public :: ocean_gm_config_t

&ocean_gm_nml: Gent-McWilliams thickness diffusion — eddy-induced bolus transport folded into continuity. Reads the slopes slot. Default off ⇒ no bolus flux.

Components

Type Visibility Attributes Name Initial
logical, public :: enable = .false.

Master switch. Default off ⇒ gm_compute_transports no-ops. Requires &ocean_slopes_nml enable (configure-time error).
real(kind=wp), public :: khth = 0.0_wp

Thickness diffusivity KhTh, m^2/s (constant-fill for v1; production 1e2-1e3). 0 ⇒ no bolus transport even when enabled.
real(kind=wp), public :: khth_max_cfl = 0.1_wp

Fraction of the diffusive CFL the face KH may use.
real(kind=wp), public :: khth_slope_max = 0.01_wp

Slope magnitude above which the safe-streamfunction blend takes over (MOM6 slope_max).
