[MITgcm-support] Dose Um_Diss involve UBotDrag term?

[杨智斌]

Sorry to disturb you again. I have a new question about vertical viscous dissipation. In my mind, the Um_Diss term also involve vertical dissipation BUT ONLY NOT using implicitViscosity. If using implicitViscosity, the vertical dissipation can be diagnosed by VISrI_Um/volume and Um_Diss will only involve horizontal dissipation, bottom drag and side drag. Am I right? Thank you in advance for your help.


Best regards.

if you use the default explicit bottom drag, then yes: the drag tendency
UBotDrag is part of Um_Diss

(just check that you have selectImplicitDrag=0 in your config output)
