subroutine latbdf(n,lll) use mod_xc ! HYCOM communication interface use mod_tides ! HYCOM tides implicit none include 'common_blocks.h' c integer n,lll c c --- apply lateral boundary conditions to barotropic flow field c c --- port flow version: c --- NOT similar to the standard 'Browning and Kreiss' MICOM/HYCOM open c --- boundary condition. This version uses algorithms based on a c --- 1 invariant Flather boundary condition (setting the gradient c --- of the incoming characteristic to zero). c c --- The tangential velocity is not constrained. c c --- see also: latbdp c c --- the code is as similar as possible to that for the standard case. c --- so for example, 'speed' is in fact 1/SQRT(gH) which represents c --- c1/g in the notation of (Bleck and Sun, Open boundary conditions c --- for MICOM). The 1/g allows for the use of pressure fields. c c --- Note that East, West, North and South refers to the grid c --- (i.e i,j points) and NOT geographic East, West, North and South c c --- the first
