¶ Control structure for MOM_marine_ice.
- Type fields:
%
kv_iceberg
[real] :: The viscosity of the icebergs [L4 Z-2 T-1 ~> m2 s-1] (for ice rigidity)%
berg_area_threshold
[real] :: Fraction of grid cell which iceberg must occupy so that fluxes below are set to zero [nondim]. (0.5 is a good value to use.) Not applied for negative values.%
latent_heat_fusion
[real] :: Latent heat of fusion [Q ~> J kg-1].%
density_iceberg
[real] :: A typical density of icebergs [R ~> kg m-3] (for ice rigidity)%
time
[type(time_type),pointer] :: A pointer to the ocean model’s clock.%
diag
[type( diag_ctrl ),pointer] :: A structure that is used to regulate the timing of diagnostic output.
