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. |
