| 28 | !! ******************** |
|---|
| 29 | !! ** Purpose : Initialize the array used for the computation of the part of |
|---|
| 30 | !! the right hand side of the barotropic streamfunction elliptic equation |
|---|
| 31 | !! associated with the open boundaries |
|---|
| 32 | !! |
|---|
| 33 | !! ** Method : |
|---|
| 34 | !! + The (i,j) indices of ocean grid-points round isolated coastlines |
|---|
| 35 | !! are found (isolated coastlines = coast lines separated by an |
|---|
| 36 | !! open boundary) from icoast array read in coastlines file. |
|---|
| 37 | !! |
|---|
| 38 | !! + read 'coastline' file initialize icoast() |
|---|
| 39 | !! modify icoast() depending on the number of open boundaries |
|---|
| 40 | !! specified through key_obc |
|---|
| 41 | !! |
|---|
| 42 | !! + compute zwb, an ocean/land mask defined as follows: |
|---|
| 43 | !! zwb(i,j) = 0. over the one isolated coastline |
|---|
| 44 | !! = -1, -2, -3 over the orthers |
|---|
| 45 | !! + for example, when 4 open boundaries are specified: |
|---|
| 46 | !! |
|---|
| 47 | !! //| |// |
