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