Such models aid blood circulation the most without cutting it off by being too tight.
These models boost your circulation and provide you with all the positives of compression therapy without making a big dent in your budget.
Given that the answer to this for atmospheric models is a resounding «NO» (particularly because of sub-grid scale processes which need to be effectively pre-ordained through parameterizations), and given that oceanic circulations have much longer adjustment time scales, yet also have much more intense small scale (gyre) circulations than the atmosphere, my instinct is that we are not even close to being able to trust ocean models without long term validation data.
Vecchi et al. compared the observed trend in the Walker circulation between 1861 and 1992 to that yielded by simulations from the GFDL CM2 general circulation model, run with and without anthropogenic forcing.
In detail the large scale circulation structure would depend on the rotation speed of the planet so it is not easy to imagine the result without some more serious modelling.
Already in an early comment in this thread I speculated that it may be impossible to do those analyses without the use of a full model of circulation.
One can not develop a useful model of what drives global ocean circulation, he says, without understanding what is happening at the scale of a cubic centimeter.
In my articles to date I have been unwilling to claim anything as grand as the creation of a new model of climate because until now I was unable to propose any solar mechanism that could result directly in global albedo changes without some other forcing agent or that could account for a direct solar cause of discontinuities in the temperature profile along the horizontal line of the oceanic thermohaline circulation.
When heavy rainfall probabilities were next investigated in ensembles of two atmospheric general circulation models, run with and without anthropogenically - induced sea surface temperature changes, results were model - dependent.
This view is supported by model results that relate the variability of the global - mean SST to North Atlantic thermohaline circulation (30, 31, 35) and by the existence of an AMO - like variability in control runs without anthropogenic forcing (28).
Nobody has created a general circulation model that can explain climate's behavior over the past century without CO2 warming.
Without studying the principles of highly - organized functioning of ecological communities, including their genetically encoded ability to respond to environmental perturbations in a non-random compensatory way, the perspectives drawn from global circulation models with respect to the climatic effects of land cover change (e.g., statements like cutting all boreal forests will ease global warming) will continue to lack any resemblance to reality.
