Description

2 improvevments for GLS:

  • scaling of mixing under sea-ice ( do as it is in TKE)
  • add limit condition under ice shelves

Implementation

improve GLS scaling of mixing under sea-ice ( do as it is in TKE)

4 options of scaling under sea oce are available for TKE;

0: no scaling

1: scale with constant sea-ice thickness

2: scaling with mean sea-ice thickness

3: scaling with max sea-ice thicknesss

only one is available for GLS: scaling with constant roughness, equivalent to CASE 1 in TKE.

  • Options 0,1,3 should be addded in GLS
  • As for TKE, nn_mxlice wil be added in namelist

add limit condition under ice shelves

Surface boundary condition should be modified under the ice-shelves seas:

  • for TKE and psi
  • for Neumann and Dirichlet conditions

Tests

GLS scaling of mixing under sea-ice

The MXLICE_ORCA2.pdf​ in #2604 show some the effects of the different scaling with GLS on the reference ORCA2_ICE configuration.

Introducing the scaling of mixing under sea-ice in GLS doesn't change the results whit default paramater (TKE). Tested with SETTE.

SETTE tests are OK when activating GLS and mixing under sea-ice.

Commited in trunk at rev 14966 (see https://forge.ipsl.jussieu.fr/nemo/changeset/14966 )

add GLS limit condition under ice shelves

Introducing the GLS limit condition under ice shelves doesn't change the results whit default paramater (TKE). Tested with SETTE.

SETTE tests are OK when activating GLS.

Commited in trunk at rev 14967 ( see https://forge.ipsl.jussieu.fr/nemo/changeset/14967 )
