This article describes the performance of several open
boundary conditions when applied to the Princeton ocean Model, a 3-D primitive
equation model designed for coastal studies. The presentation is divided in two
parts. The first part evaluates the performance of radiation condition,
characteristic methods, and relaxation schemes applied to the barotropic mode.
According to these experiments the open boundary conditions with the best
overall performance are the relaxation schemes proposed by Martinsen and Engedahl
(1987), and the radiation condition suggested by Flather (1976), supplemented
with a local solution suggested by Roed and Smedstad (1984) for wind-drivenn
problems. The second part of this study evaluates the performance of a selected
set of open boundary conditions for the fully 3-D model. The particular problem
to be discussed is the wind driven upwelling of a coastal region. The first set
of experiments are conducted in an idealized domain to allow comparions of the
numerical results with theory. Following the idealized experiments the model is
used to investigate tha coastal upwelling of the Chilean coast.
