|---|
| 74 | !! ** Purpose : Locate island grid-points from mbathy array |
|---|
| 75 | !! |
|---|
| 76 | !! ** Method : The coordinates of ocean grid-points round an island |
|---|
| 77 | !! are found from mbathy array read or computed in dommba. |
|---|
| 78 | !! we first compute zwb, an ocean/land mask defined as follows: |
|---|
| 79 | !! zwb(i,j) = 0. over the main land and the ocean |
|---|
| 80 | !! = -n over the nth island |
|---|
| 81 | !! With the proper boundary conditions (defined by nperio) |
|---|
| 82 | !! Note: IF i,j are the coordinates of an ocean grid-point west |
|---|
| 83 | !! or east of a island, the corresponding coordinates miisl(ip,4,n) |
|---|
| 84 | !! or mjisl(ip,2,n) are those of the western or southern side of |
|---|
| 85 | !! the island (i.e. i+1 ou j+1, respectively) |
|---|
| 86 | !! |
|---|
| 87 | !! ** Action : compute mnisl, miisl, mjisl arrays defined as: |
|---|
| 88 | !! mnisl(i,n) : nb of grid-points along (i=0), north (i=1), north |
|---|
| 89 | !! (i=1), south (i=2), east (i=3), or west (i=4) of the nth island |
|---|
| 90 | !! miisl(ip,i,n), mjisl(ip,i,n) : (i,j) index of ipth u- or v-point |
|---|
