Sentences with phrase «slab ocean models»

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.

Regarding «runaway greenhouse», we've found parameter values in our AGCM + slab ocean model that seem to generate a runaway warming under 2xCO2.

Regarding «runaway greenhouse», we've found parameter values in our AGCM + slab ocean model that seem to generate a runaway warming under 2xCO2.

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.

The slab ocean model is a computationally efficient scheme that allows sea surface temperatures to interact with the atmosphere; and is necessary for propagating energy imbalances due to land cover change that lead to shifts in precipitation.

All runs are conducted using preindustrial (1850) land use conditions in order to conform with our best - available slab ocean model data; however the orbital conditions are set for the year 2000.

Here we explain this interhemispheric asymmetry using an atmospheric general circulation model coupled to a slab ocean model.

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):

You get very similar results using slab oceans (no changes in transports etc.), and similar results using very different conceptual models — in this sense it is a robust result.

In CMIP3, an AGCM was coupled to a non-dynamic mixed - layer (slab) ocean model with prescribed ocean heat transport convergence.

By default, water at the surface does not move (a «slab ocean»), but it is also possible to prescribe ocean heat transport or to take wind - driven ocean heat transport in low latitudes into account through a simple one - dimensional model driven by surface winds.

Until recently, «oceans» in climate models were very simple, in effect just large «slabs».

Right, they model the «globe» with a 500 meter slab ocean and find that the real world ocean which is only 8 times larger acts different.

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.

This result from a slab ocean configuration without ocean currents is illustrative and could vary from model to model, though it is similar to results from the fully coupled version in a subsequent study (Kharin and Zwiers, 2000).

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).

Transient climate response (TCR) and equilibrium climate sensitivity (ECS) were calculated by the modelling groups (using atmosphere models coupled to slab ocean for equilibrium climate sensitivity), except those in italics, which were calculated from simulations in the MMD at PCMDI.

«CMIP3 - AO» denotes twentieth century experiment by atmosphere — ocean coupled general circulation model (GCM), and «CMIP3 - AS» denotes control experiment by atmosphere - slab ocean coupled GCM.

In simple terms the red assumption is compatable with a slab ocean thermal model and I don't think that is an appropriate model and seems incompatable with the data.

In HadSM3, a motionless 50 m slab ocean is coupled to the atmospheric model and ocean heat transport is diagnosed for each member.
