10    C These are input arrays (of integers) that contain the *absolute*
11    C computational index of an open-boundary (OB) point.
12    C A zero (0) element means there is no corresponding OB in that column/row.
13    C The computational coordinate refers to "tracer" cells.
14    C For a northern/southern OB, the OB V point is to the south/north.
15    C For an eastern/western OB, the OB U point is to the west/east.
16    C eg.
17    C     OB_Jnorth(3)=34  means that:
18    C          T( 3 ,34) is a an OB point
19    C          U(3:4,34) is a an OB point
20    C          V( 4 ,34) is a an OB point
21    C while
22    C     OB_Jsouth(3)=1  means that:
23    C          T( 3 ,1) is a an OB point
24    C          U(3:4,1) is a an OB point
25    C          V( 4 ,2) is a an OB point
26    C
27    C For convenience, negative values for Jnorth/Ieast refer to
28    C points relative to the Northern/Eastern edges of the model
29    C eg. OB_Jnorth(3)=-1  means that the point (3,Ny) is a northern O-B.
