[MITgcm-support] 回复： vertical momentum tendency

[钱钰坤]

Hi Haoran,


Thank you for your help.  But I don't really know how these two diagnostics
could help in deriving the tendency of w (unit of acceleration).


My understanding is that these two diagnostics are useful in calculating the
eddy momentum flux when the output is time-average <> one.  For example,
<w'u'> = <wu> - <w><u>
If we output monthly mean wu, w, and u, we can get eddy flux <w'u'> for this
month.



  Best regards

Hi，
 If I understand correctly,these two diagnostics could help.




WU_VEL  |WU      LR|m.m/s^2         |Vertical Transport of Zonal Momentum WV_VEL  |WV      LR|m.m/s^2         |Vertical Transport of Meridional Momentum

Hi all,


Just a quick question.  Why there is no tendency of vertical momentum,
like TOTWTEND, in the diagnostics even the non-hydrostatic option is
turned on?


To close the energy budget, I guess we need this diagnostic.  Is there any
workaround to obtain it if there is no TOTWTEND?




 Best regards.
