|---|
| 605 | !! provide the ocean heat and freshwater fluxes. |
|---|
| 606 | !! |
|---|
| 607 | !! ** Method : - Receive all the atmospheric fields (stored in frcv array). called at each time step. |
|---|
| 608 | !! OASIS controls if there is something do receive or not. nrcvinfo contains the info |
|---|
| 609 | !! to know if the field was really received or not |
|---|
| 610 | !! |
|---|
| 611 | !! --> If ocean stress was really received: |
|---|
| 612 | !! |
|---|
| 613 | !! - transform the received ocean stress vector from the received |
|---|
| 614 | !! referential and grid into an atmosphere-ocean stress in |
|---|
| 615 | !! the (i,j) ocean referencial and at the ocean velocity point. |
|---|
| 616 | !! The received stress are : |
|---|
| 617 | !! - defined by 3 components (if cartesian coordinate) |
|---|
| 618 | !! or by 2 components (if spherical) |
|---|
| 619 | !! - oriented along geographical coordinate (if eastward-northward) |
|---|
| 620 | !! or along the local grid coordinate (if local grid) |
|---|
| 621 | !! - given at U- and V-point, resp. if received on 2 grids |
|---|
| 622 | !! or at T-point if received on 1 grid |
|---|
| 623 | !! Therefore and if necessary, they are successively |
|---|
| 624 | !! processed in order to obtain them |
|---|
| 625 | !! first as 2 components on the sphere |
|---|
