But a continuous coastline is represented by a steplike boundary.
The oceanic circulation is a boundary value Problem
Coastline representation could have a serious influence on the final
result.
If so, should we change to other models which treat more naturally the boundary?
NO-SLIP ( ) condition valid for viscous fluid (the ocean).
But resolution usually too coarse. This encouraged the
use of other types of boundary condition (FREE-SLIP, ).
But they could yield different behavior and circulation.
