The researchers then used the
model to investigate how
slabs of ocean crust would behave as they travel down toward the lower mantle.
Surprise find The team's actual mission was to survey
ocean currents near the Ross Ice Shelf, a
slab of ice extending more than 600 miles (970 kilometers) northward from the grounding zone
of the West Antarctic Ice Sheet into the Ross Sea, to
model the behavior
of a drill string, a length
of pipe extending to the seafloor which delivers drilling fluids and retrieves sediment samples.
A — I think they call it a «swamp
ocean», or maybe a
slab ocean — heat capacity may be
modelled (I won't write it in computer code exactly; T is temperature, ECS is equlibrium climate sensitivity here expressed as K per doubling
of CO2, y = year number):
I saw a poster a at a meeting last year that compared a simulation with prescribed SST to another with a
slab ocean model (SOM) and the results were very striking, so I started thinking that I need to explore this type
of modelling more.
CP rationalized doing so on the basis that cool runs (nearly 50 %
of the control runs) were not realistic and reflected, e.g., the simple
slab ocean in their
model.
In general, the pattern
of change in return values for 20 - year extreme temperature events from an equilibrium simulation for doubled CO2 with a global atmospheric
model coupled to a non-dynamic
slab ocean shows moderate increases over
oceans and larger increases over land masses (Zwiers and Kharin, 1998; Figure 9.29).
Some recent results with AGCMs coupled to
slab ocean models (Hewitt et al., 2001; Vavrus and Harrison, 2003) support the hypothesis that a representation
of sea ice dynamics in climate
models has a moderating impact on climate sensitivity.
