Abstract
QUODDY
, a
3-D
finite
element
numerical
ocean
model
,
is
used
to
study
the
ocean
circulation
variability
over
the
Labrador
Shelf
and
Newfoundland
Shelf
, and the
evolution
patterns
of the
model
temperature
,
salinity
and
currents.
The
effects
of
two
different
nudging
schemes
on the
model
solution
are
examined.
One
approach
is
to
restore
the
model
temperature
and
salinity
toward
their
initial
values
(for
the
first
M2
cycle)
or
toward
evolving
immediately
preceding
M2
cycle
mean
values
(for
the
second
and
subsequent
M2
cycle).
The
other
approach
is
to
fix
the
density
but
allow
dynamical
evolution
of
temperature
and
salinity.
The
moored
measurements
are
used
to
evaluate
the
model
circulation
results
and
harmonic
tidal
analysis
is
used
to
analyze
the
simulated
tidal
results.
The
model
simulated
circulations
are
generally
consistent
with
observations.
The
current
comparison
statistics
indicate
good
qualitative
agreement
and
approximate
quantitative
agreement
with
moored
measurements.
The
comparison
of
two
different
schemes
shows
that the
nudging
approach
of
T/S
is
conceptually
and
dynamically
more
realistic
than the
pure
diagnostic
one.
Tidal
model
results
are
consistent
with those from
previous
studies.
