C !DESCRIPTION: |
| 21 |
C Calculates the tendency of a tracer due to advection and diffusion. |
| 22 |
C It calculates the fluxes in each direction indepentently and then |
| 23 |
C sets the tendency to the divergence of these fluxes. The advective |
| 24 |
C fluxes are only calculated here when using the linear advection schemes |
| 25 |
C otherwise only the diffusive and parameterized fluxes are calculated. |
| 26 |
C |
| 27 |
C Contributions to the flux are calculated and added: |
| 28 |
C \begin{equation*} |
| 29 |
C {\bf F} = {\bf F}_{adv} + {\bf F}_{diff} +{\bf F}_{GM} + {\bf F}_{KPP} |
| 30 |
C \end{equation*} |
| 31 |
C |
| 32 |
C The tendency is the divergence of the fluxes: |
| 33 |
C \begin{equation*} |
| 34 |
C G_\theta = G_\theta + \nabla \cdot {\bf F} |
| 35 |
C \end{equation*} |
| 36 |
C |
| 37 |
C The tendency is assumed to contain data on entry. |
