C | SUBROUTINE CALC_GS |

|
|
C | o Calculate the salt tendency terms. |

C | A procedure called EXTERNAL_FORCING_S is called from |
| 23 |
|
|
C | here. These procedures can be used to add per problem |
| 24 |
|
|
C | E-P flux source terms. |
| 25 |
|
|
C | Note: Although it is slightly counter-intuitive the |
| 26 |
|
|
C | EXTERNAL_FORCING routine is not the place to put |
| 27 |
|
|
C | file I/O. Instead files that are required to |
| 28 |
|
|
C | calculate the external source terms are generally |
| 29 |
|
|
C | read during the model main loop. This makes the |
| 30 |
|
|
C | logisitics of multi-processing simpler and also |
| 31 |
|
|
C | makes the adjoint generation simpler. It also |
| 32 |
|
|
C | allows for I/O to overlap computation where that |
| 33 |
|
|
C | is supported by hardware. |
| 34 |
|
|
C | Aside from the problem specific term the code here |
| 35 |
|
|
C | forms the tendency terms due to advection and mixing |
| 36 |
|
|
C | The baseline implementation here uses a centered |
| 37 |
|
|
C | difference form for the advection term and a tensorial |
| 38 |
|
|
C | divergence of a flux form for the diffusive term. The |
| 39 |
|
|
C | diffusive term is formulated so that isopycnal mixing and |
| 40 |
|
|
C | GM-style subgrid-scale terms can be incorporated b simply |
| 41 |
|
|
C | setting the diffusion tensor terms appropriately. |
