[MITgcm-support] Selecting advection scheme

[Edward W Doddridge]

Hi Saeid,

I’m moving this to its own thread, since your question is unrelated to the subject of the email.

The advection scheme is selected based on the numerical argument you provide as `tempAdvScheme`  or `saltAdvScheme` in your data file. For example, to use the Prather (1986) scheme you would have

 tempAdvScheme=80,
 saltAdvScheme=80,

in `data`.

There is documentation of the different advection schemes here<http://mitgcm.org/public/r2_manual/latest/online_documents/node72.html> and here<http://mitgcm.org/public/r2_manual/latest/online_documents/node77.html>. A table showing the numerical values you need to enter to select each advection scheme is here<http://mitgcm.org/public/r2_manual/latest/online_documents/node82.html>.

Cheers,
Ed

Hi everyone,
I am trying to model currents circulation so how can I select the code of advection scheme in the parameter file (e.g., tempAdvScheme and saltAdvScheme) in file data?
which I can see temperature an salinity changes? basically on what basis these codes are selected?

Best,
Saeid

Hi Chen,

set these two variables to zero, then there will be no heat or freshwater flux
SHELFICEheatTransCoeff = 0.
SHELFICEsaltTransCoeff = 0.

or if you use SHELFICEuseGammaFrict=.TRUE., then set
shiCdrag = 0.

I mean, I want to turn a sub-ice-shelf cavity into a sill cavity to assess the thermodynamic and dynamic effect induced by the ice shelf. If there is another method to achieve my idea, please tell me that. Many thanks.
