|---|
| 53 | !! *** ROUTINE dom_msk *** |
|---|
| 54 | !! |
|---|
| 55 | !! ** Purpose : Compute land/ocean mask arrays at tracer points, hori- |
|---|
| 56 | !! zontal velocity points (u & v), vorticity points (f) and baro- |
|---|
| 57 | !! tropic stream function points (b). |
|---|
| 58 | !! Set mbathy to the number of non-zero w-levels of a water column |
|---|
| 59 | !! |
|---|
| 60 | !! ** Method : The ocean/land mask is computed from the basin bathy- |
|---|
| 61 | !! metry in level (mbathy) which is defined or read in dommba. |
|---|
| 62 | !! mbathy equals 0 over continental T-point |
|---|
| 63 | !! and the number of ocean level over the ocean. |
|---|
| 64 | !! |
|---|
| 65 | !! At a given position (ji,jj,jk) the ocean/land mask is given by: |
|---|
| 66 | !! t-point : 0. IF mbathy( ji ,jj) =< 0 |
|---|
| 67 | !! 1. IF mbathy( ji ,jj) >= jk |
|---|
| 68 | !! u-point : 0. IF mbathy( ji ,jj) or mbathy(ji+1, jj ) =< 0 |
|---|
| 69 | !! 1. IF mbathy( ji ,jj) and mbathy(ji+1, jj ) >= jk. |
|---|
| 70 | !! v-point : 0. IF mbathy( ji ,jj) or mbathy( ji ,jj+1) =< 0 |
|---|
| 71 | !! 1. IF mbathy( ji ,jj) and mbathy( ji ,jj+1) >= jk. |
|---|
| 72 | !! f-point : 0. IF mbathy( ji ,jj) or mbathy( ji ,jj+1) |
|---|
| 73 | !! or mbathy(ji+1,jj) or mbathy(ji+1,jj+1) =< 0 |
|---|
| 74 | !! 1. IF mbathy( ji ,jj) and mbathy( ji ,jj+1) |
|---|
| 75 | !! and mbathy(ji+1,jj) and mbathy(ji+1,jj+1) >= jk. |
|---|
| 76 | !! b-point : the same definition as for f-point of the first ocean |
|---|
| 77 | !! level (surface level) but with 0 along coastlines. |
|---|
| 78 | !! |
|---|
| 79 | !! The lateral friction is set through the value of fmask along |
|---|
| 80 | !! the coast and topography. This value is defined by rn_shlat, a |
|---|
| 81 | !! namelist parameter: |
|---|
| 82 | !! rn_shlat = 0, free slip (no shear along the coast) |
|---|
| 83 | !! rn_shlat = 2, no slip (specified zero velocity at the coast) |
|---|
| 84 | !! 0 < rn_shlat < 2, partial slip | non-linear velocity profile |
|---|
| 85 | !! 2 < rn_shlat, strong slip | in the lateral boundary layer |
|---|
| 86 | !! |
|---|
| 87 | !! N.B. If nperio not equal to 0, the land/ocean mask arrays |
|---|
| 88 | !! are defined with the proper value at lateral domain boundaries, |
|---|
| 89 | !! but bmask. indeed, bmask defined the domain over which the |
|---|
| 90 | !! barotropic stream function is computed. this domain cannot |
|---|
| 91 | !! contain identical columns because the matrix associated with |
|---|
| 92 | !! the barotropic stream function equation is then no more inverti- |
|---|
| 93 | !! ble. therefore bmask is set to 0 along lateral domain boundaries |
|---|
| 94 | !! even IF nperio is not zero. |
|---|
| 95 | !! |
|---|
| 96 | !! In case of open boundaries (lk_obc=T): |
|---|
| 97 | !! - tmask is set to 1 on the points to be computed bay the open |
|---|
| 98 | !! boundaries routines. |
|---|
| 99 | !! - bmask is set to 0 on the open boundaries. |
|---|
| 100 | !! |
|---|
| 101 | !! Set mbathy to the number of non-zero w-levels of a water column |
|---|
| 102 | !! mbathy = min( mbathy, 1 ) + 1 |
|---|
