C !DESCRIPTION: |
19 |
C Calculates the tendancy of a tracer due to advection and diffusion. |
20 |
C It calculates the fluxes in each direction indepentently and then |
21 |
C sets the tendancy to the divergence of these fluxes. The advective |
22 |
C fluxes are only calculated here when using the linear advection schemes |
23 |
C otherwise only the diffusive and parameterized fluxes are calculated. |
24 |
C |
25 |
C Contributions to the flux are calculated and added: |
26 |
C \begin{equation*} |
27 |
C {\bf F} = {\bf F}_{adv} + {\bf F}_{diff} +{\bf F}_{GM} + {\bf F}_{KPP} |
28 |
C \end{equation*} |
29 |
C |
30 |
C The tendancy is the divergence of the fluxes: |
31 |
C \begin{equation*} |
32 |
C G_\theta = G_\theta + \nabla \cdot {\bf F} |
33 |
C \end{equation*} |
34 |
C |
35 |
C The tendancy is assumed to contain data on entry. |
