481    C These are input arrays (of integers) that contain the *absolute*
482    C computational index of an open-boundary (OB) point.
483    C A zero (0) element means there is no corresponding OB in that column/row.
484    C The computational coordinate refers to "tracer" cells.
485    C For a northern/southern OB, the OB V point is to the south/north.
486    C For an eastern/western OB, the OB U point is to the west/east.
487    C eg.
488    C     OB_Jnorth(3)=34  means that:
489    C          T( 3 ,34) is a an OB point
490    C          U(3:4,34) is a an OB point
491    C          V( 4 ,34) is a an OB point

495    C          U(3:4,1) is a an OB point
496    C          V( 4 ,2) is a an OB point
497    C
498    C For convenience, negative values for Jnorth/Ieast refer to
499    C points relative to the Northern/Eastern edges of the model
500    C eg. OB_Jnorth(3)=-1  means that the point (3,Ny-1) is a northern O-B.
