C !DESCRIPTION: |
24 |
C Calculates the tendency of a sea-ice field due to advection. |
25 |
C It uses the multi-dimensional method given in \ref{sect:multiDimAdvection} |
26 |
C and can only be used for the non-linear advection schemes such as the |
27 |
C direct-space-time method and flux-limiters. |
28 |
C |
29 |
C This routine is an adaption of the GAD_ADVECTION for 2D-fields. |
30 |
C for Area, effective thickness or other "extensive" sea-ice field, |
31 |
C the contribution iceFld*div(u) (that is present in gad_advection) |
32 |
C is not included here. |
33 |
C |
34 |
C The algorithm is as follows: |
35 |
C \begin{itemize} |
36 |
C \item{$\theta^{(n+1/2)} = \theta^{(n)} |
37 |
C - \Delta t \partial_x (u\theta^{(n)}) + \theta^{(n)} \partial_x u$} |
38 |
C \item{$\theta^{(n+2/2)} = \theta^{(n+1/2)} |
39 |
C - \Delta t \partial_y (v\theta^{(n+1/2)}) + \theta^{(n)} \partial_y v$} |
40 |
C \item{$G_\theta = ( \theta^{(n+2/2)} - \theta^{(n)} )/\Delta t$} |
41 |
C \end{itemize} |
42 |
C |
43 |
C The tendency (output) is over-written by this routine. |
