| 22 |
C *==========================================================* |
| 23 |
C | SUBROUTINE SALT_INTEGRATE |
| 24 |
C | o Calculate tendency for salinity and integrates |
| 25 |
C | forward in time. The salinity array is updated here |
| 26 |
C | while adjustments (filters, conv.adjustment) are applied |
| 27 |
C | later, in S/R TRACERS_CORRECTION_STEP. |
| 28 |
C *==========================================================* |
| 29 |
C | A procedure called APPLY_FORCING_S is called from |
| 30 |
C | here. These procedures can be used to add per problem |
| 31 |
C | E-P flux source terms. |
| 32 |
C | Note: Although it is slightly counter-intuitive the |
| 33 |
C | EXTERNAL_FORCING routine is not the place to put |
| 34 |
C | file I/O. Instead files that are required to |
| 35 |
C | calculate the external source terms are generally |
| 36 |
C | read during the model main loop. This makes the |
| 37 |
C | logistics of multi-processing simpler and also |
| 38 |
C | makes the adjoint generation simpler. It also |
| 39 |
C | allows for I/O to overlap computation where that |
| 40 |
C | is supported by hardware. |
| 41 |
C | Aside from the problem specific term the code here |
| 42 |
C | forms the tendency terms due to advection and mixing |
| 43 |
C | The baseline implementation here uses a centered |
| 44 |
C | difference form for the advection term and a tensorial |
| 45 |
C | divergence of a flux form for the diffusive term. The |
| 46 |
C | diffusive term is formulated so that isopycnal mixing |
| 47 |
C | and GM-style subgrid-scale terms can be incorporated by |
| 48 |
C | simply setting the diffusion tensor terms appropriately. |
