PHC_44 run

This run is based on the PHC_37 one except that:

  • nn_fwb=0 no freshwater correction
  • TKE penetration is fixed to 10% instead 5%

Few patterns list:

- Thermocline warmer than in PHC_37 
- salinity decrease O(-0.1 PSU) at 100 meters all around Antarctica and Arctic bassins
whereas an increase by O(0.1 PSU) arises in eastern part of Atlantic and Pacific oceans  
- SSS decrease despite the strong damping term
- in zonal mean -0.1 PSU over 300 meters beyond 50°N and S
- temperature strongly increase beyond 0.2 °C / PHC_37 at 100 meters everywhere but under sea-ice
where the wind module is set to zero in TKE
- SST patterns are cooler than in PHC37 in tropiacal and sub-polar gyres by -0.2°C whereas a small 
warming in the equatorial strip 
- in zonal mean -0.3°C off the Antarctic over 300 meters depth
- strong reduction over ~300 meters on the top part of the Deacon cell by -3 Sv 
- deeper MXL especially along the ACC path O(+50m)
- shallower MXL in main North deep water formation areas
- increase in tropical gyres of the Net surface heat fluxes / PHC_37 ~O(-3 w.m-2)
