zdfgls: error in bottom friction formulation

Description

The GLS scheme has been developed in v3.1, i.e. with an implicit computation of the bottom friction. Since v3.2 the bottom friction is explicit, therefore there is no need of wbot(u and v) saved in restart. Furthermore, the bottom friction is now proportional to the before velocity, not the after velocity (as stated in dynzdf_imp.F90) or to now velocity (as stated in zdfbfr.F90).

In addition, rn_hbro defined in zdfbfr.F90 is only used in zdfgls.F90 and it is not a namelist parameter. It should be defined in zdfgls and renamed hbro

  • Resolution set to fixed
  • Status changed from new to closed

Actions:

  • wbotu wbotv removed from dynzdf_imp, zdfbfr and zdfgls
  • zdfgls: compute the bottom friction module using bfrua, bfrva coeff and before velocities. rename rn_hbro
  • zdfbfr: move the definition of bfrua, bfrva in zdf_oce and so remove USE zdfbfr from zdftke
