|
|
C Purpose: SUBROUTINE EXCH_UV_BGRID_3D_RX |
| 18 |
|
|
C handle exchanges for a 3D vector field on an B-grid. |

|
|
C |
| 20 |
|
|
C Input: |
| 21 |
|
|
C uPhi(lon,lat,levs,bi,bj) :: first component of vector |
| 22 |
|
|
C vPhi(lon,lat,levs,bi,bj) :: second component of vector |
| 23 |
|
|
C withSigns (logical) :: true to use sign of components |
| 24 |
|
|
C myNz :: 3rd dimension of input arrays uPhi,vPhi |
| 25 |
|
|
C myThid :: my Thread Id number |
| 26 |
|
|
C |
| 27 |
|
|
C Output: uPhi and vPhi are updated (halo regions filled) |
| 28 |
|
|
C |
| 29 |
|
|
C Branch to appropriate exchange routine for B-grid vector field |
