A
Right
so
we're
gonna
step
away
from
coupled
modeling
for
a
moment
and
just
come
and
look
at
the
ocean,
and
so
what
the
work
that
I've
been
doing
for
this
project
is
looking
at
very
idealized,
Coastline
shapes
and
their
influence
on
the
meridianal
overturning
circulation,
and
this
is
work
that
I've
been
doing
with
my
advisors,
Kyle
armor
and
Luanne
Thompson
at
the
University
of
Washington
and
with
Andrew
Xiao
at
UVic
and
David
Darr
at
University
of
Washington
as
well
and
I
also
have
a
long
list
of
acknowledgments.
A
Etc
with
this
long
list
of
people,
so,
as
probably
everybody
knows,
there's
this
circulation,
asymmetry
between
the
Atlantic
and
the
indo-pacific,
and
so
in
the
Atlantic
there's
Northern
High
latitude,
deep
ventilation.
A
A
And
so
previous
studies
that
have
looked
at
why
this
deep
ventilation
is
confined
to
the
Atlantic,
have
looked
at
two
factors:
one
being
Basin
width
and
the
other
being
the
ex
Southern
extent
of
the
continent
along
the
ocean
basins.
So
as
these
Studies
have
art,
one
of
these
studies
has
sort
of
been
alluded
to
already
in
this
webinar
series.
But
there's
this
series
of
Marshall
at
all
aquaplanet
simulations
and
this
one
is
from
ferriera
at
all.
A
Where
there's
these
dark
blue
lines
are
our
ridges
that
extend
from
the
bottom
of
the
ocean
to
the
surface,
and
you
can
see
that
so
this
colors
are
a
convective
index
and
when
you
have
one
Ridge,
you
get
convection
at
all
all
longitudes
at
the
North
Pole,
but
when
you
put
in
the
second
Ridge
and
you
create
two
basins
but
with
Drake
passages
or
just
you
know,
with
a
Southern
Ocean,
your
convection
is
confined
to
the
this
narrower
Basin
and
then
other
Studies
have
looked
at
this
Southern
extent
of
the
primarily
the
African
continent
and
whether
it
when
it
close,
comes
closer
to
the
maximum
wind
stress
line
in
the
Southern
Ocean.
A
A
And,
like
I
said,
where
I'm
doing
an
ocean
only
modeling
study
and
these
results
have
been
looked
at
in
Ocean,
only
models
as
well
and
I'm,
going
to
highlight
two
such
experiments
by
Jones
and
Chessie,
and
by
Tessie
and
Jones
and
they're,
using
MIT
GCM
to
determine
the
effect
of
both
the
Atlantic
base
and
width
and
the
southern
extent
of
the
African
continent,
and
so
their
their
model.
A
Configuration
is
a
one
degree
resolution
constant
surface,
forcing
without
any
seasonality,
they're
using
a
temperature
relaxation,
a
linear
equation
of
state
and
no
sea
ice
so
similar
to
the
coupled
studies.
A
They
find
that
a
shorter
African
continent
increases
the
overturning
circulation
in
the
small
Basin
and
the
Basin
width
matters
as
well
so
having
a
narrow,
Atlantic
Basin
increases
your
overturning
relative
to
having
a
wide
Atlantic
basin,
and
the
argument
here
is
that
the
the
subpolar
western
boundary
current
scales,
linear
with
Lee
with
base
and
width
so
having
a
narrower
base
in,
weakens
your
Southward
flowing
western
boundary
current
and
allows
subtropical
western
boundary
current
to
bring
saltier
water
farther
north
densifying,
the
North
Atlantic.
A
So
the
motivating
questions
for
this
study
here
is
that
previously
people
have
focused
on
the
width
of
the
Basin
and
the
Continental
extents,
but
not
people
don't
really
talk
about
the
cosine
shape
along
the
Atlantic
and
whether
or
not
that
has
an
impact
on
on
the
Atlantic,
radional
overturning
and
then
second,
a
second
question
is
basically
what
role
does
base
and
geometry
play
in
the
global
ocean
circulation.
A
So
this
this
whole
webinar
is
about
idealized,
modeling
and
sort
of
the
the
benefits
to
having
a
hierarchy
of
of
models
with
increasing
complexity.
So
this
is
a
modeling
toolbox
that
sort
of
that
Andrew
and
David
and
I
have
been
developing,
and
we
can
use
this
to
ask
fundamental
questions
about
ocean
circulation,
so
so
the
model
that
I'm
using
is
obviously
mom.
A
Six,
that's
what
this
whole
thing
is
about
and
like
xiaoming,
we
we
have
to
have
land
caps
since
we're
not
using
a
cube
sphere
grid,
and
we
want
our
polls
to
be
over
land
caps,
I'm
using
a
two
degree
resolution,
31
vertical
levels
and
I've
coupled
months
to
assist
two,
and
these
are
the
six
different
configurations
that
I'll
be
looking
at.
So
the
first
is
this
Aqua
quasi-aqua,
similar
to
shonings.
A
The
second
is
this
straight
Coast
configuration
in
which
we
have
a
small
atlantic-like
Basin
and
then
a
larger
Pacific,
Basin
and
one
continent
is
shorter
than
the
other.
This
wide
straight
configuration
in
which
I
narrow
the
land
strips
to
make
the
Atlantic
wider,
but
I
don't
change
the
shape
of
the
Pacific.
A
Both
Coast
widens
the
Atlantic
Basin
by
the
same
average
amount
as
wide
straight,
but
does
so
in
this
this
way,
where
I
try
to
make
the
the
cosines
look
like
idealized
versions
of
the
real
world,
so
this
is
sort
of
like
the
American
coast
along
the
Atlantic,
and
this
is
sort
of
the
African
coast
along
the
Atlantic,
and
then
this
Africa
coast
and
America
Coast
cases.
A
Look
at
the
impacts
of
both
of
those
coastlines
separately,
so
the
forcing
for
this
ocean
sea
ice
model
is
done
through
bulk
formula
but
I'm,
starting
from
the
core
normal
year,
2.0,
forcing
where
I
took
the
the
zonal
mean
of
the
Southern
Hemisphere
after
applying
a
land
mask
and
only
taking
the
the
points
over
ocean
mirroring
that
above
over
the
Equator,
so
that
I
have
the
same
forcings
over
the
northern
and
southern
hemispheres,
but
Shifting
the
Northern
Hemisphere
from
the
Southern
Hemisphere
by
six
months
to
preserve
seasonality
and
all
of
the
results
that
we're
looking
at
today
are
from
600
years
of
spin
up,
but
I'm
going
to
continue
to
run
those
out
for
longer,
because
here
we
do
care
about
the
deep
ocean
coming
into
equilibrium
or
I
care,
I
care.
A
So
to
look
at
some
results
now,
as
sort
of
expected.
The
aqua
case
is
very
symmetric
between
the
two
hemispheres.
So
we
look.
If
we
look
at
the
sea
surface
salinity
and
the
Sea
surface
temperature,
we
get
the
subtropics
kind
of
pop
out
as
very
salty,
and
then
we
have
our
equatorial
upwelling
band
and
yeah.
A
We
get
cooler
as
we
go
from
the
equator
to
the
pole,
so
pretty
much
what
we
expected
to
see
and
then,
when
we
have
two
basins,
the
small
Basin
is
warmer
and
saltier
than
the
large
Basin
in
this
the
Northern
Hemisphere
so
and
I
think
you
know
we
expected
to
see
this
as
well.
Based
on
previous
studies,.
A
And
with
two
basins,
the
overturning
the
Deep
ventilation
is
is
in
the
smaller
Basin.
So
this
is
the
residual
amine
overturning
in
this
straight
Coast
case
in
the
atlantic-like
Basin,
and
this
is
in
the
Pacific
like
basin
and
I
wanted
to
take
a
look
at
sort
of
a
measure
of
the
stratification
in
over
the
global
ocean.
A
So
this
is
the
density
at
1000
meters,
minus
the
density
at
the
surface,
and
so
places
where
that
are
lighter
in
color
are
less
stratified,
and
so
this
North
Atlantic
region
pops
out
as
the
most
unstably
stratified
part
of
the
ocean,
which
is
what
we
expect,
because
that's
where
the
Deep
convection
is
carrying
the
deep
water
formation-
and
this
is
just
a
a
zonal-
mean
of
the
Atlantic
Basin
of
this
Delta
Rosy
density.
Difference
from
1000
meters
to
zero
meters.
A
And
so
now,
I'm
going
to
look
at
anomalies
from
the
straight
Coast
case
and
so
widening
the
Basin
and
looking
at
this
wide
straight
simulation
decreases:
the
stratification
in
the
North
Atlantic.
So
just
if
we
look
at
the
zonal
mean
profile
here,
we
can
see
that
in
the
North
Atlantic
we
get
less
stratified
and
we
get
yeah
so
I'm
looking
at
this
region
here
and
we
get
a
stronger
overturning
circulation
in
the
Atlantic
Basin.
A
So
this
is
interesting
because
it
is
inconsistent
with
the
Real
Results
that
I
pointed
out
earlier
from
Jones
and
Chessie
and
I
guess
sort
of
one
big
difference
in
this
and
it's
kind
of
comparing
apples
to
oranges,
because
what
I'm
doing
here
is
widening
the
Basin
by
narrowing
the
strips
of
land,
whereas
what
they
do
is
they
change
the
shape
of
their
domain?
So
that's
one
big
difference
and
perhaps
narrowing
the
land
in
the
igules
region
is
allowing
for
easier
import
of
salt
into
this
Basin
via
the
warm
route.
Exchange.
A
A
Anomaly
looks
very
different
than
it
did
in
just
the
the
wide
Coast
case
as
well,
so
there's
a
very
different
impact
on
the
meridianal
overturning
circulation
when
you
change
the
shape
of
the
coastlines
compared
to
when
you
simply
widen
the
Basin,
and
so
that's
my
like
first
takeaway
and
first
key
point
is
that
the
average
width
of
the
Basin
is
not
enough
to
predict
how
amok
will
change
between
all
these
cases.
The
shape
with
which
the
Basin
size
changes
is
what
matters
most
for
a
mock
changes.
A
And
so
looking
at
just
the
case,
the
effect
of
the
African
Coast
having
this
chunk
basically
cut
out
of
the
continent
here,
decreases
the
stratification
in
this
atlantic-like
Basin
by
a
small
amount
and
increases
the
overturning
circulation
in
the
Atlantic
and
looking
at
the
effect
of
the
American
Coastline,
we
can
see
that
we
that
decreases
the
stratification
in
the
northern
part
of
the
Atlantic
like
Basin
and
increases
the
mock,
particularly
in
the
northern
part
of
the
Basin
as
well,
and
so
I
wanted
to
look
at
whether
the
Eastern
or
the
western
coastline
had
a
larger
impact
on
the
mock.
A
The
the
magnitudes
in
the
the
changes
to
the
amok
have
a
are
pretty
similar,
but
the
patterns
themselves
are
very
different,
so
it
does
look
like
you
know.
The
cosine
shape
does
matter
for
for
mock
and
just
naively
I
wanted
to
add
these
anomalies
together
to
see
if
they
looked
like
the
anomaly
from
the
impact
of
having
both
coastlines
shaped,
and
they
do
not
add
linearly
so
I,
don't
know
if
I
expected
them
to
I
just
was
curious
to
see
if
they
had
a
linear
relationship
or
not
so
I.
A
So
as
a
sort
of
an
intermediate
step,
we
can
look
at
existing
theories
for
amox
strength,
that
link
meridianal
density,
difference
along
the
western
boundary
to
amok
strength
and
depth,
and
so
this
is
from
a
paper
by
Butler
at
all.
But
it's
also
sort
of
inspired
by
a
2010
Deborah
at
all
paper,
and
so
we
start
from
thermal
wind
and
scale
the
thermal
wind
with
typical
values
found
in
the
Atlantic.
A
A
So
that's
this
right
here.
So
we
can
replace
the
zonal
density
gradient
and
the
zonal
length
scale
with
the
merional
density
gradient
and
the
meridional
length
scale,
and
the
reason
that
I
was
interested
in
the
scaling
was
because
a
big
thing
that
I'm
changing
is
just
the
western
boundary
and
so
I
expected
that
the
western
boundary
current
would
change.
A
And
so
this
is
a
way
to
relate
that
to
the
overturning
strength
and
so
from
this
scaled
thermal
wind,
and
when
we
replace
the
density
difference,
then
we
can
zonally
integrate
and
get
an
expression
for
for
V,
and
then
we
can
integrate
that
again
to
get
an
expression
for
the
overturning
circulation,
and
so
from
this
expression
we
can
see
that
the
overturning
should
be
proportional
to
the
zonal
length
scale
and
to
the
twice
vertically
integrated
meridianal
density
difference
along
the
western
boundary.
A
So
this
is
just
a
picture
of
that.
This
dotted
line
is
the
predicted
overturning,
whereas
the
solid
line
is
the
overturning
from
the
model,
and
I
should
mention
that
sort
of
following
what
Butler
had
all
do
in
their
2016
paper.
This.
A
This
solid
line
is
not
from
one
latitude,
it's
from
30
South
to
60
North,
which
is
where
I
do
the
radial
density
difference
from
the
latitudes
from
which
I
I
get
them
right.
Now,
on
density,
difference
and
I
just
take
the
maximum
overturning
strength
between
those
two
latitudes
at
each
depth.
A
So
now
we
can
look
at
what
overturning
strength
we
can
predict
for
each
of
the
cases,
and
so,
like
I,
showed
before
the
straight
Coast
case.
This
lies
pretty
much
right
on
top
of
this
predicted
overturning
stream
function,
and
the
same
goes
for
the
wide
straight
and
I
I.
Guess
again,
I
want
to
point
out
that
the
differences
in
overturning
in
this
predicted
overturning
strength
comes
from
the
meridianal
density
gradient
along
the
western
boundary
and
the
Basin
width.
A
And
then
the
both
coasts
fall
somewhere
in
between
both
in
the
model
output
and
in
the
predicted
overturning
and
then
the
Africa
Coast
Falls,
very
close
to
the
straight
Coast
case
in
both
model
output
and
predicted,
and
the
America
Coast
Falls,
very
close
to
the
both
Coast
case.
In
the
model
output
and
in
the
predicted.
A
A
So
just
a
quick
recap
of
what
we've
talked
about
so
far.
The
first
point
that
I
really
want
to
make
is
that
average
Basin
width
doesn't
tell
the
whole
story.
Basin
shape
matters
for
changes
in
overturning
strength
and
depth
between
all
of
these
different
simulations.
That
I've
showed
and
then
key
Point
number
two
is
that
amox
strength
and
depth
scale
well
and
can
be
predicted
with
meridiano
density
difference,
even
with
different
Atlantic,
basing
geometries
and
so
I.
A
I
would
argue
that
this
highlights
a
fundamental
physical
relationship
between
the
western
boundary
density
difference
and
the
meridianal
overturning
circulation
in
the
Atlantic,
and
so
just
a
few
points
that
I've
sort
of
been
thinking
about
and
I
think
are
interesting
to
to
discuss
is
that
it
seems
like
amok,
is
most
sensitive
to
the
cosine
shape
and
cosine
width
in
the
North
Atlantic
subpolar
dire
region,
because
the
the
wide
straight
case
widens
everywhere,
whereas
the
both
Coast
case
widens
only
in
certain
with
a
certain
pattern
but
I
don't
really
change
the
shape
or
the
width
of
the
Basin
in
the
North
Atlantic
subpolar
dryer.
A
A
second
point
is
that
the
width
of
the
southern
tip
of
Africa
matters
for
the
warm
route
exchange
between
basins
or
at
least
I,
think
it
does.
It
should,
and
not
just
the
latitudinal
extent
of
that
continent
and
then
I
think.
The
third
point
is
that
these
density
scalings
raise
possible
implications
for
gcms
that
have
biases
in
their
amox
strength
and
also
I
mentioned
I.
Don't
I,
don't
show
it
here,
but
I've
been
looking
more
at
sort
of
what
creates
this?
What
what
dominates
this?
A
This
density
difference
and
it's
the
it
seems
like
the
northern
Point
matters
more
than
the
southern
point,
when
I
take
the
difference,
and
so
maybe
there's
a
potential
tuning
knob
for
for
gcms.
A
If
we
want
to
change
a
mark,
strength
or
depth
by
looking
at
how
to
by
looking
at
this
Northern
western
boundary
current
and
the
density
there,
and
just
a
quick
mention
of
future
work
that
I'm
thinking
of
doing
with
this
modeling
setup,
like
I,
mentioned
I'm,
trying
to
link
now
mechanistically,
what's
happening
in
the
western
boundary
current,
and
why
these
density
differences
are
arising.
In
these
different
cases,
two
either
like
the
salinity,
transport
or
western
boundary.
A
Dynamics
I've
also
been
I've
coupled
this
ocean
sea
ice
model
to
am2,
and
that's
something
that
I'm
interested
in
pursuing
a
lot
of
different
experiments
with
in
the
future
and
I've
I've
received
help
on
that
from
from
Liz
maroon
and
Andrew
Xiao
and
David
Darr
as
well,
and
then
I
didn't
even
talk
about
the
Pacific
Basin
today.
But
if
you
were
looking
as
we
were
flipping
through
all
the
different
overturning
figures.
A
There's
some
changes
that
occur
in
the
overturning
circulation
in
the
Pacific,
which
I
think
are
really
interesting
and
so
I
think
I
would
like
to
do
a
study
that
focuses
on
the
large
Basin
as
it
seems
like
there's
sort
of
a
an
overturning
compensation
that
occurs
when
you
change
the
Atlantic
Coastline,
but
but
don't
change
the
Pacific
coastline
yeah.
So
that's
it
from
me.
You
can
stop
sharing.
In
the
end,
all.
C
Sarah
thanks
for
that
very
nice
presentation
am
I
correct
that
all
of
your
changes
to
the
land
sea
is
with
a
vertical
wall
and,
if
so,
have
you
considered
the
contribution
from
sloping
side,
boundaries,
shelves
and
other
things,
in
particular
with
relation
to
transient
stability?
Variability
such
questions,
in
addition
to
Vertical
walls,
which
the
ocean
has
none
right.
A
The
engine
does
not
have
vertical
walls,
but
this
model
definitely
only
has
vertical
walls
and
I
guess
I,
that's
something
else
that
I
should
have
put
in
the
Future
Works
side.
This
is
something
that
I've
been
talking
to.
Henry
Drake
about
is
looking
at
putting
in
slipping
sidewalls
and
Mom.
Six
is
good
for
that
too,
because
of
the
ale
remapping,
but
yeah.
It's
not
something
that
I've
done
yet
or
looked
at
yet,
but
I
would
like
to
in
the
future.
E
A
Yeah
I'm,
sorry,
I,
didn't
I,
didn't,
say
this,
but
all
of
them,
I
meant
to
say
that's
all
of
the
mock
that
I
show
is
calculated
on
isopicinal,
coordinates
and
then
just
remap
to
Dead
Space
for
ease
of
looking
at
for
this
presentation.
F
What
hi
nice
talk,
I
may
have
just
missed
this,
but
I
was
wondering
with
the
scaling
what
your
thoughts
are
about
sort
of
the
time
scales
on
which
this
applies.
F
A
Yeah,
so
it
is
a
it's
sort
of
an
equilibrium
scaling,
so
I
am
thinking
on
longer
time,
scales
and
and
I
I
haven't
really
been
thinking
about
the
transient.
A
It's
a
good
question:
I,
don't
know
how
well
it
would
apply
to
like
you
know,
maybe
the
first
100
Years
of
the
simulation.
Yes
I,
don't
have
a
satisfying
response
for
you
I
think,
but
you
are
correct
in
assuming
that
this
is
a
longer
term.
Equilibrium
type
scaling.
B
Okay,
thanks
who
Kim.
G
Hi
thanks
for
the
nice,
sir,
so
I
have
a
question
about
the
the
African
Coast.
So
when
you
explain
the
difference
between
the
two
different
basin
with
cases
you
said
the
the
the
what
is
it
the
narrower
Africa
Coast
brings
more
easily
the
city
of
water
into
Atlantic
Ocean.
But
when.
F
G
See
the
the
sharper
African
Coast
I,
don't
see
that
kind
of
strong
difference
so
yeah
whether
you're
interpretation
is
for
the
chakra
African
coasters.
A
Yeah,
that's
a
great
question
so
right
so
I
said,
I
said
that
that
narrowing
the
Atlantic
coast
could
allow
for
more
salt
to
be
imported
into
the
Atlantic
Basin.
But
the
mock
for
the
Africa
Coast
is
not
so
different
from
the
mock
for
the
straight
Coast
and
I
I.
Think
and
I
I
haven't
really
been
able
to
answer
that.
Yet.
But
I
I
think
that
because
I
think
yeah
so
I
think
it's
kind
of
has
to
do
with
the
the
Basin
width
in
the
subpolar
gyre
region.
A
Not
changing
I
I,
don't
I,
don't
again,
I,
don't
have
a
great
answer
as
I'm
still
sort
of
digging
into
this.
But
I
do
think
that,
like
sort
of,
if
you
had
to
pick
two
regions
where
the
coastline
shape
or
the
cosine
or
sort
of
like
the
base
and
width
matters,
most
I
I,
my
attention
has
been
drawn
to
that
Northern.
A
So
the
polar
gyro
region
as
being
really
important
for
mock
strength,
as
well
as
to
the
the
width
of
that
the
South
African
land
mass,
so
I,
think
they're,
sort
of
competing
effects
and
I
haven't
been
able
to
work
out
sort
of
the
nuances
there.
Yet.
G
A
Oh
yeah,
so
I
I,
don't
don't
change
the
surface,
forcing
between
all
the
all
of
his
I
guess:
there's
sort
of
varying
land.
G
Because
my
question
is
whether
there's
more
energy
input
when
you
you
know
when
you
make
it
narrower
or
wider,
then
you
know:
if
you
there's
more
energy
input,
then
there
could
be
more
stronger,
hey
Mark,
vice
versa,
yeah!
That's
that's
my
question.
A
Yeah
question
I,
don't
think
I've
enough
to
like
fully
comment
which
I
think
that
yeah
I
I
I'll
I'll
take
a
look
at
that.
Thanks
for
the
suggestion.
A
D
A
That's
all
right
question,
that's
a
great
question:
I
mean
if
you
think
about
sort
of
like
the
barotropic
circulation.
A
It's
not
out
of
the
question
that
that
that
assumption
is
a
pretty
good
one.
It
still
sort
of
feels
like
I
I
talk
about
this
assumption,
a
lot
with
my
advisors
and
it
still
sort
of
feels
like
magic
in
a
way
to
me
like.
Why
does
that
work?
I
A
Yeah,
actually,
right
now,
what
I'm
doing
for
K
is
I'm
just
using
the
value
that
Butler
at
all
use
in
their
paper.
So
they
sort
of
are
fitting.
There
predicted
to
sort
of
model
output
fight
they
just
sort
of
fit
a
line
of
their
predicted
to
model
output,
and
they
they
look
at
a
bunch
of
different
simulations
with
different
forcings
and
yeah
I.
Don't
I,
don't
I,
don't
know
how
to
choose
K,
because
I
don't
have
very
many
simulations,
a
very
small
end,
but
yeah
I
I,
don't
know.
D
D
Good,
you
have
a
bit
of
magic
in
your
simulation,
yeah.
B
Okay,
Pedro
you're
up
next
awesome.
H
Thank
you,
hi
Sarah,
thank
you
for
your
results.
I
have
a
question
that
might
be
in
the
Jones
and
Jesse
paper,
so
in
the
small
basic
wine
facing
simulation
is
the
Atlantic
salt
here,
because
there's
an
a-mog
or
there's
an
a-mog,
because
the
Atlantic
is
Soldier,
I.
Think
what
what
a
related
question
that
will
help
me
understand
the
simulation.
H
All
right
and
fourth
thing
is
like
e
minus
B
that
I'm
assuming
you're
applying
to
this
simulation
is
zonal.
Uniform
in
the
simulation
and
also
I,
was
wondering
what
what
do
you
do
with
the
winds?
It
just
takes.
Zone
I
mean
profile,
so
I
was
wondering
if
you
could
comment
on
that
Baseline
simulation
and
why
it
shows
such
a
much
saltier
Atlantic.
A
Yeah
I
am
trying
to
figure
out
the
salt
as
well
on
my
myself,
so
the
the
salt
transport
is
sort
of
difficult
to
look
at
because
it
yeah
the
the
E
minus
P
sort
of
varies
because
the
E
is
not
prescribed
right.
The
prescription,
the
precipitation
is
prescribed
and
it's
a
zonal
mean,
but
evaporation
is
allowed
to
vary
so
I
kind
of
get
confused
and
I
haven't
fully
worked
out
sort
of
like
the
salt
transport.
A
Yet
because
the
advection
and
the
diffusion
are
of
salt
are
both
kind
of.
Sometimes
there
are
different
magnitudes
I
I'm,
looking
into
like
understanding,
The
Assault
transport
and
whether
that
comes
first
or
mock
develops
first,
and
then
you
get
the
salt
of
action
feedback
in
terms
of
the
forcings
I.
Think
you
yeah,
you
were
asking
about
the
wind
forcings,
so
those
are
also
yeah.
Those
are
just
zonal
means
from
each
latitude,
but
there
is
seasonality,
so
they
are
they're.
Definitely
stronger.
A
You
know
in
the
winter,
then
in
the
summer
and
I
did
yeah.
There's
I
did
do
some
smoothing
of
the
Winds
so
that
they
go
to
zero
at
the
edge
of
the
land
caps.
But
yeah
other
than
that,
their
zonal
means
from
from
the
core.
H
So
what
I
gather
is
that
you
still
have
a
temperature
effect
on
evaporation,
but
wins
that
prescribed
and
are
certainly
uniform.
The
two
basins
have
the
same
winds
and
the
rainfall
is
the
same
in
the
two
basins.
So
then
it
has
to
be
the
temperature
effect
on
evaporation
which
could
control
e
minus
B
or
it
could
be
Dynamics.
H
H
D
J
D
Now
the
change
was
because
of
that
relation
to
the
position
of
the
wind
stress
curl
was
that
right.
A
A
I
think
so,
based
on
the
the
coupled
simulation,
the
Nelson
at
all
2016.
is
that
the
one
that
I
talked
about
or
maybe
okay
actually
is
the
fairy
era
at
all
2018
that
they
have
a
remote
review
paper,
but
I
think
that
maybe
it
I
think
that
I
would
expect
the
same
effect.
A
But
I
guess
you
have
to
be
careful
because
I
wonder
if
you,
you
move
the
maximum
wind
stress
line
very
far
south,
so
that
it's
even
farther
south
than
the
extent
of
the
South
America.
Maybe
you
would
have
different
effects
there
as
well,
but.
K
A
L
Palmer
thanks
that
was
a
really
nice
talk,
Sarah
the
the
back
and
forth
with
Pedro
kind
of
brings
to
mind
something
that
people
have
been
working
on
off
and
on
for
years
where,
instead
of
prescribing
the
precipitation
as
just
a
field,
you
use
the
fact
that,
for
water
at
least
what
comes
down
has
to
have
come
up
and
that
the
atmosphere
doesn't
really
distribute
moisture
terribly
far.
L
It
can
distribute
heat,
enormous
distances,
but
moisture
mostly
gets
rung
out,
and
so
people
have
introduced
idealized
models
where
the
precipitation
anomalies
are
kind
of
a
local
diffusive
balance
of
the
evaporation
anomalies
with
a
length
scale
of
maybe
100
a
thousand
kilometers
or
something
in
the
atmosphere
as
a
way
of
kind
of
getting
away
from
this
mixed
boundary
condition
sorts
of
issues
with
amok
that
people
have
noted
going
back
now,
20
25
years.
L
It
strikes
me
that,
having
that
kind
of
capability
in
the
idealized
atmosphere
could
actually
be
really
valuable
for
the
sorts
of
studies
that
that
you're
doing
kind
of
the
the
counterpart
of
what
the
atmospheric
folks
have
been
doing
for
years,
where
they
prescribe
the
ocean
properties
in
some
very
idealized
way.
But
these
things
have
tended
to
show
up
in
a
paper
and
then
they
die
in
part
because
there
isn't
a
an
appropriate
software
repository
and
a
host
institution
to
take
them
on
and
say.
Okay,
this
is
useful.
Let's
keep
it
around.
L
It
seems
to
me
like
this.
This
exercise
that
we've
been
talking
about
today
might
be
just
the
sort
of
thing
to
to
kind
of
give
us
these
kind
of
idealized
atmospheric
capabilities
to
allow
you
to
address
exactly
the
sorts
of
questions
that
you
and
Pedro
were
talking
about
a
few
minutes
ago.
A
Yeah,
that
would
be
great
I,
don't
I'm,
assuming
mom
six
doesn't
really
have
that
sort
of
built-in
already,
but
maybe
you
could
add
it.
A
Okay,
maybe
ncar
could
add
it
in
the
yeah
I
guess
that's
a
maybe
a
comment
for
sure.
J
I
think
one
another
aspect
of
this:
the
community,
the
funding,
Community
projects,
is
sort
of
setting
up
a
library
or
repository
where
these
sorts
of
cases
can
live
and
people
can
go
back
and
reference
them
later
and
see
how
someone
implemented
something
like
that.
Yeah.
M
Yeah
I
think
the
challenge
is
kind
of
the
balance
between
like
we
can't
support
everything
as
kind
of
out
of
the
box
configurations,
or
it
just
gets
completely
out
of
hand.
But
it
would
be
great
if
we
could
have
a
repository
where,
if
someone
has
has
done
something
that
they
could
post
a
recipe
of
how
they
have
done
it,
that
could
hopefully
apply
in
future
versions
as
well,
and
then,
if
there
are
particular
configurations
where,
like
they're
really
popular
many
people
are
using
them.
Then
then
there's
enough
motivation
for
them
to
become
officially
supported.
B
Okay,
Chris,
let's
see
again,
okay.
N
I
just
wanted
to
to
say
that
Bob
suggestion
is
a
great
suggestion,
because
I
I
too,
have
sort
of
been
lamenting
that
these
these
ideas
for
implementing
the
simplified
ocean
or
a
simplified
atmosphere
for
Ocean
Models,
similar
to
the
way
that
people
do
slave
oceans
do
seem
to
be
sort
of
scattered
around.
It's
basically
impossible
to
grab
them
for
yourself.
So
it
would
be
great
to
have
a
centralized
place
for
all
those
things.
K
Ahead
sure,
just
a
quick
comment
on
this:
that's
a
really
good
point:
Bob
I've
been
talking
with
Ryan,
Abernathy
and
Laura
Zana
about
trying
to
get
some
momentum
to
maybe
do
something
like
cheap
AML,
but
for
Mom
six,
which
I
think
is
what
you're
describing
that
would
do
things
like
exact
heat
around
and
moisture
around
and
maybe
have
a
diffuse,
the
more
static
energy
as
well,
basically
mimicking
all
the
essential
features
of
an
atmosphere
as
far
as
I'm
concerned
diffusion
by
static
energy,
but
into
as
a
boundary
condition,
I
think,
there's
a
lot
of
cool
work.
K
B
All
right:
well,
this
is
a
great
interactive
session.
Oh
go
ahead,
Bob
can
I
follow.
L
Up
on
that,
so
this
is.
This
is
something
where
the
question
of
whether
this
is
an
ocean
only
sort
of
capability
of
whether
this
is
something
that
you
would
like
to
be
a
part
of
the
coupled
system,
so
that
maybe
it's
used
to
drive
an
ice
ocean
model,
I
think
Sarah
you're
using
a
notion
only
configuration
one
could
easily
imagine
that
this
sort
of
idealized
atmosphere
could
be
very
useful
with
an
ice
model,
maybe
some
kind
of
a
simplified
land
model.
L
But
thinking
about
this
as
a
capability
of
the
coupled
system,
the
cesm
system,
I,
don't
know
if
you'd
want
to
do
it
twice
once
each
way
or
whether
you
want
to
kind
of
build
it
into
the
system,
but
it
I
I
think
there's
a
lot
of
possibilities
there
for
the
sorts
of
idealized
climate
sensitivity,
studies
that
that
we
heard
several
of
today
and
I
I,
but
I
agree
with
Carl
Kyle
that
it's
we
could
look
into
doing
this
as
a
mom-6
specific
capability
as
well.
