Description

  • improve 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
