C | o SUBROUTINE KPP_TRANSPORT_S | |

C | Add non local KPP transport term (ghat) to diffusive | |
| 15 |
C | salinity flux. | |
| 16 |
C |==========================================================| |
| 17 |
C | The nonlocal transport term is nonzero only for scalars | |
| 18 |
C | in unstable (convective) forcing conditions. | |
| 19 |
C | Note: KPPdiffKzS(-,k) is defined at the top of grid cell | |
| 20 |
C | k while KPPghat(i,j,k,bi,bj) is defined at the | |
| 21 |
C | bottom of grid cell k. | |
| 22 |
C | For K=1, KPPdiffKzS(-,k) = 0 which insures no flux | |
| 23 |
C | through the surface. | |
