C These are input arrays (of integers) that contain the *absolute* |
64 |
C computational index of an open-boundary (OB) point. |
65 |
C A zero (0) element means there is no corresponding OB in that column/row. |
66 |
C The computational coordinate refers to "tracer" cells. |
67 |
C For a northern/southern OB, the OB V point is to the south/north. |
68 |
C For an eastern/western OB, the OB U point is to the west/east. |
69 |
C eg. |
70 |
C OB_Jnorth(3)=34 means that: |
71 |
C T( 3 ,34) is a an OB point |
72 |
C U(3:4,34) is a an OB point |
73 |
C V( 4 ,34) is a an OB point |
74 |
C while |
75 |
C OB_Jsouth(3)=1 means that: |
76 |
C T( 3 ,1) is a an OB point |
77 |
C U(3:4,1) is a an OB point |
78 |
C V( 4 ,2) is a an OB point |
79 |
C |
80 |
C For convenience, negative values for Jnorth/Ieast refer to |
81 |
C points relative to the Northern/Eastern edges of the model |
82 |
C eg. OB_Jnorth(3)=-1 means that the point (3,Ny) is a northern O-B. |
83 |
C |
84 |
C With exch2, the global domain used for specifying the boundary (and |
85 |
C boundary value files) is different for N,S and E,W boundaries: |
86 |
C - for N,S, the facets are stacked in x (like W2_mapIO=-1) |
87 |
C - for E,W, the facets are stacked in y, so that E,W boundaries in |
88 |
C different facets cannot have the same I |
