|---|
| 70 | !! ** Purpose : Compute the now trend due to the surface pressure |
|---|
| 71 | !! gradient in case of free surface formulation with time-splitting. |
|---|
| 72 | !! Add it to the general trend of momentum equation. |
|---|
| 73 | !! Compute the free surface. |
|---|
| 74 | !! |
|---|
| 75 | !! ** Method : Free surface formulation with time-splitting |
|---|
| 76 | !! -1- Save the vertically integrated trend. This general trend is |
|---|
| 77 | !! held constant over the barotropic integration. |
|---|
| 78 | !! The Coriolis force is removed from the general trend as the |
|---|
| 79 | !! surface gradient and the Coriolis force are updated within |
|---|
| 80 | !! the barotropic integration. |
|---|
| 81 | !! -2- Barotropic loop : updates of sea surface height (ssha_e) and |
|---|
| 82 | !! barotropic transports (ua_e and va_e) through barotropic |
|---|
| 83 | !! momentum and continuity integration. Barotropic former |
|---|
| 84 | !! variables are time averaging over the full barotropic cycle |
|---|
| 85 | !! (= 2 * baroclinic time step) and saved in zsshX_b, zuX_b |
|---|
| 86 | !! and zvX_b (X specifying after, now or before). |
|---|
| 87 | !! -3- Update of sea surface height from time averaged barotropic |
|---|
| 88 | !! variables. |
|---|
| 89 | !! - apply lateral boundary conditions on sshn. |
|---|
| 90 | !! -4- The new general trend becomes : |
|---|
| 91 | !! ua = ua - sum_k(ua)/H + ( zua_b - sum_k(ub) )/H |
|---|
| 92 | !! |
|---|
| 93 | !! ** Action : - Update (ua,va) with the surf. pressure gradient trend |
