[MITgcm-support] tidal forcing and wind forcing

[Himansu Pradhan]

Hi MITgcm users,


I am giving tidal forcing to the model in  code/external_forcing.F in its
momentum equations i.e. by adding tidal forcing terms to "gU" and "gV".
Thus the model simulations shows oscillations in tidal frequency in the
density/velocity field representing internal waves. This is fine.  (say
EXP_1)


But, when i prescribe "wind stress" to the model (in input/data.exf) along
with the background tidal forcing (in code/external_forcing.F) , the
simulations give the effect only due to tide (say EXP_2). The wind driven
circulation is not represented  in the output ???  The model results for
EXP_1 and EXP_2 are same !!!!!!!


note:

(i) to see the wind driven circulation i average velovity field for 5 to 7
days.


(ii) The wind driven circulation is very well represented daily and monthly
basis  ( when daily/monthly winds are given as input to the model) , when
tidal forcing are not added in the momentum equations.
