Sentences with phrase «slab ocean»

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.

IIRC (which I might not — twas a while ago), in our MIROC ensemble (slab ocean GCM), members with high eqm climate sensitivity also had high control temperature.

Previous studies demonstrated that the cloud feedbacks derived from the Cess experiments well capture the intermodel differences of feedbacks in the equilibrium response of slab ocean models to a doubling of CO2 (e.g., Ringer et al. 2006).

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

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.

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.

This is coupled to a motionless 50 m depth slab ocean.

Left column is the name of ensembles, and in the second left column, «AOGCM» denotes atmosphere — ocean coupled GCM, and «ASGCM» denotes atmosphere - slab ocean coupled GCM.

It is noteworthy that very different models have been used for this: Annan et al. (2005) used an atmospheric GCM with a simple slab ocean, Schneider et al. (2006) the intermediate - complexity model CLIMBER - 2 (with both ocean and atmosphere of intermediate complexity), while the new Schmittner et al. study uses an oceanic GCM coupled to a simple energy - balance atmosphere (UVic).

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.

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.

We have developed an energetically consistent framework for driving LES, in which the LES domain is coupled to a simple slab ocean.

To achieve this, we couple the LES domain to a slab ocean model, whose SST evolves according to the surface energy balance.

I've messed around with a slab ocean configuration, which I wrote another post on, but I've always wanted to try a fully coupled simulation.

The only alternative way around this, if you really want seasons, is to first run a fully coupled or a slab ocean simulation and create the SST input data from that.

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.

We use the National Center for Atmospheric Research (NCAR) Community Earth System Model version 1.3 (CESM) that couples the Community Atmosphere Model version 5 (CAM5)[28] to the Community Land Model (CLM4.5; [29]-RRB-, the CICE4 sea ice model [30], and implements a slab ocean with prescribed heat transport derived from a fully - coupled ocean - atmosphere simulation [28].

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.

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).

«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.

I've discussed one aquaplanet study of TCs using a slab ocean, Merlis et al 2013, in post # 42.

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.

The cooling versions almost certainly have cold patches on the equator which is a known unrealistic effect that can develop when you use a slab ocean.

These aquaplanet simulations are sometimes run with prescribed sea surface temperatures (SSTs) and sometimes with prescribed heat flux through the surface (usually realized by running the atmosphere over a «slab ocean» s saturated surface with some heat capacity, and specifying an «oceanic heat flux» into or out of the slab.

In these ensembles, atmosphere — ocean coupled (AO), atmosphere - slab ocean coupled (AS), and atmosphsere - only (A) global climate models are used.

Historical simulations by atmosphere — ocean coupled model (CMIP3 - AO) and the control simulations by atmosphere - slab ocean coupled (CMIP3 - AS) are used for analysis.
