44 | !! *** ROUTINE dom_msk *** |
---|
45 | !! |
---|
46 | !! ** Purpose : Compute land/ocean mask arrays at tracer points, hori- |
---|
47 | !! zontal velocity points (u & v), vorticity points (f) and baro- |
---|
48 | !! tropic stream function points (b). |
---|
49 | !! Set mbathy to the number of non-zero w-levels of a water column |
---|
50 | !! (if island in the domain (lk_isl=T), this is done latter in |
---|
51 | !! routine solver_init) |
---|
52 | !! |
---|
53 | !! ** Method : The ocean/land mask is computed from the basin bathy- |
---|
54 | !! metry in level (mbathy) which is defined or read in dommba. |
---|
55 | !! mbathy equals 0 over continental T-point, -n over the nth |
---|
56 | !! island T-point, and the number of ocean level over the ocean. |
---|
57 | !! |
---|
58 | !! At a given position (ji,jj,jk) the ocean/land mask is given by: |
---|
59 | !! t-point : 0. IF mbathy( ji ,jj) =< 0 |
---|
60 | !! 1. IF mbathy( ji ,jj) >= jk |
---|
61 | !! u-point : 0. IF mbathy( ji ,jj) or mbathy(ji+1, jj ) =< 0 |
---|
62 | !! 1. IF mbathy( ji ,jj) and mbathy(ji+1, jj ) >= jk. |
---|
63 | !! v-point : 0. IF mbathy( ji ,jj) or mbathy( ji ,jj+1) =< 0 |
---|
64 | !! 1. IF mbathy( ji ,jj) and mbathy( ji ,jj+1) >= jk. |
---|
65 | !! f-point : 0. IF mbathy( ji ,jj) or mbathy( ji ,jj+1) |
---|
66 | !! or mbathy(ji+1,jj) or mbathy(ji+1,jj+1) =< 0 |
---|
67 | !! 1. IF mbathy( ji ,jj) and mbathy( ji ,jj+1) |
---|
68 | !! and mbathy(ji+1,jj) and mbathy(ji+1,jj+1) >= jk. |
---|
69 | !! b-point : the same definition as for f-point of the first ocean |
---|
70 | !! level (surface level) but with 0 along coastlines. |
---|
71 | !! |
---|
72 | !! The lateral friction is set through the value of fmask along |
---|
73 | !! the coast and topography. This value is defined by shlat, a |
---|
74 | !! namelist parameter: |
---|
75 | !! shlat = 0, free slip (no shear along the coast) |
---|
76 | !! shlat = 2, no slip (specified zero velocity at the coast) |
---|
77 | !! 0 < shlat < 2, partial slip | non-linear velocity profile |
---|
78 | !! 2 < shlat, strong slip | in the lateral boundary layer |
---|
79 | !! |
---|
80 | !! N.B. If nperio not equal to 0, the land/ocean mask arrays |
---|
81 | !! are defined with the proper value at lateral domain boundaries, |
---|
82 | !! but bmask. indeed, bmask defined the domain over which the |
---|
83 | !! barotropic stream function is computed. this domain cannot |
---|
84 | !! contain identical columns because the matrix associated with |
---|
85 | !! the barotropic stream function equation is then no more inverti- |
---|
86 | !! ble. therefore bmask is set to 0 along lateral domain boundaries |
---|
87 | !! even IF nperio is not zero. |
---|
88 | !! |
---|
89 | !! In case of open boundaries (lk_obc=T): |
---|
90 | !! - tmask is set to 1 on the points to be computed bay the open |
---|
91 | !! boundaries routines. |
---|
92 | !! - bmask is set to 0 on the open boundaries. |
---|
93 | !! |
---|
94 | !! Set mbathy to the number of non-zero w-levels of a water column |
---|
95 | !! mbathy = min( mbathy, 1 ) + 1 |
---|
96 | !! (note that the minimum value of mbathy is 2). |
---|
97 | !! |
---|
98 | !! ** Action : |
---|
99 | !! tmask : land/ocean mask at t-point (=0. or 1.) |
---|
100 | !! umask : land/ocean mask at u-point (=0. or 1.) |
---|
101 | !! vmask : land/ocean mask at v-point (=0. or 1.) |
