|---|
| 66 | !! |
|---|
| 67 | !! ** Purpose : Compute the now trend due to the surface pressure |
|---|
| 68 | !! gradient for the rigid-lid case, add it to the general trend of |
|---|
| 69 | !! momentum equation. |
|---|
| 70 | !! |
|---|
| 71 | !! ** Method : Rigid-lid appromimation: the surface pressure gradient |
|---|
| 72 | !! is given by: |
|---|
| 73 | !! spgu = 1/rau0 d/dx(ps) = Mu + 1/(hu e2u) dj-1(bsfd) |
|---|
| 74 | !! spgv = 1/rau0 d/dy(ps) = Mv - 1/(hv e1v) di-1(bsfd) |
|---|
| 75 | !! where (Mu,Mv) is the vertically averaged momentum trend (i.e. |
|---|
| 76 | !! the vertical ponderated sum of the general momentum trend), |
|---|
| 77 | !! and bsfd is the barotropic streamfunction trend. |
|---|
| 78 | !! The trend is computed as follows: |
|---|
| 79 | !! -1- compute the vertically averaged momentum trend (Mu,Mv) |
|---|
| 80 | !! -2- compute the barotropic streamfunction trend by solving an |
|---|
| 81 | !! ellipic equation using a diagonal preconditioned conjugate |
|---|
| 82 | !! gradient or a successive-over-relaxation method (depending |
|---|
| 83 | !! on nsolv, a namelist parameter). |
|---|
| 84 | !! -3- add to bsfd the island trends if lk_isl=T |
|---|
| 85 | !! -4- compute the after streamfunction is for further diagnos- |
|---|
| 86 | !! tics using a leap-frog scheme. |
|---|
| 87 | !! -5- add the momentum trend associated with the surface pres- |
|---|
| 88 | !! sure gradient to the general trend. |
|---|
| 89 | !! |
|---|
| 90 | !! ** Action : - Update (ua,va) with the surf. pressure gradient trend |
