C | o SUBROUTINE KPP_TRANSPORT_PTR |
| 16 |
C | Add non local KPP transport term (ghat) to diffusive |
| 17 |
C | passive tracer flux. |
| 18 |
C *==========================================================* |
| 19 |
C | The nonlocal transport term is nonzero only for scalars |
| 20 |
C | in unstable (convective) forcing conditions. |
| 21 |
C | Note: We do not have a specific KPP diffusion for a |
| 22 |
C | passive tracer; use Salinity diffusion instead |
| 23 |
C | Note: KPPdiffKzS(-,k) is defined at the top of grid cell |
| 24 |
C | k while KPPghat(i,j,k,bi,bj) is defined at the |
| 25 |
C | bottom of grid cell k. |
| 26 |
C | For K=1, KPPdiffKzS(-,k) = 0 which insures no flux |
| 27 |
C | through the surface. |
