[MITgcm-support] instability with shelf ice package

[刘成彦]

Dear all:
 
     I am still trying to set up a regional experiment with OBCS in the Prydz Bay. In order to get a proper simulation in this Antarctic region, I set up this
experiment with obcs package, seaice package, shelf ice package. When I start to run this model, it blows up very soon. Then, I start to check which package
should be Responsible for this. When I turn off the shelf ice package, by deleting useSHELFICE = .TRUE. in the data.pkg, the model runs very well. So, I
believe that the setting for the shelfice package should be something wrong in my simulation.

     To search some possible clues, I went to the description of the shelf ice package in the manual again. In 6.6.3.2, it says “If you use it together with vertical
mixing schemes, be aware, that non-local parameterizations have been turned off, e.g. for KPP”. Does it mean, when I want to use shelfice, I have to stop use
KPP, i.e., when I set useSHELFICE = .TRUE. in the data.pkg, I have to delete useKPP = .TRUE. If I have to delete useKPP = .TRUE. in the data.pkg, what else
vertical mixing scheme could be used in my case.
 
Thank you for your considerations!
Cheers, Liu
