C *==========================================================* |
| 20 |
C | Terms are evaluated one layer at a time working from | |
| 21 |
C | the bottom to the top. The vertically integrated | |
| 22 |
C | barotropic flow tendency term is evluated by summing the | |
| 23 |
C | tendencies. | |

C | Notes: | |
| 25 |
C | We have not sorted out an entirely satisfactory formula | |
| 26 |
C | for the diffusion equation bc with lopping. The present | |
| 27 |
C | form produces a diffusive flux that does not scale with | |
| 28 |
C | open-area. Need to do something to solidfy this and to | |
| 29 |
C | deal "properly" with thin walls. | |
