Fully coupled atmosphere -
ocean model of the three - dimensional global climate.
In lieu of a deeper understanding, legacy code used
in ocean models has largely represented the marine ecosystem and the biochemical processes that make up the marine ecosystem using simplified equations.
They used a high -
resolution ocean model that has been shown to do a good job of matching direct satellite observations of the global ocean system.
There is a well - known problem of
layered ocean models and another problem of which layers can or should be used in connection with statements on climate change.
When ocean models were first coupled to atmospheric models well over a quarter century ago, systematic errors in each component near their interface led to sizeable drift and unrealistic climate simulations.
The paper also describes an atmosphere -
ocean modeling study of feedback loops caused by ice sheet melting under 2 °C conditions.

Concentration is on the combination of acoustics
with ocean models at all frequencies and ocean scales.
This code, along with a version generated at GFDL and UCLA / NCAR by Bert Semtner, is the ancestor of many of the level -
coordinate ocean model codes run around the world today.
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.
An even more up to date way to get transports in the ocean is to
use ocean models constraint by observations (so called data assimilation or ocean state estimation in several forms).
Eddy -
resolving ocean models with chemistry and biology need to be tested and validated in a transient mode, and the prognostic aspects of marine ecosystems including nutrient dynamics need greater attention at basin and global scales.
This year we received 14 June SIO submissions from dynamical models, of which 3 were from ice -
ocean models forced by atmospheric reanalysis or other atmospheric model output and 12 were from fully - coupled general circulation models.
One of the main changes in the HadGEM3 family of models compared with previous versions is the inclusion of the
NEMO ocean modelling framework, which is also used in the Met Office's ocean forecasting system, and CICE, the Los Alamos sea ice model.
A researcher from the Finnish Meteorological Institute has been participating in a comparison of how well
global ocean models respond to the changes to sea ice and close - to - surface water.
Kauker et al., 3.5 ± 0.5, Modeling For the present outlook the coupled ice -
ocean model NAOSIM has been forced with atmospheric surface data from January 1948 to May 31 2013.
Time series of AMOC anomaly at 1000 m depth at 45 ° N (top panels) and 26.5 ° N (bottom panels) for the set of ocean reanalysis products (left panels) and the set of No Assimilation forced
ocean model simulations (right panels).
In contrast, the updated ensemble forecast from a coupled ice -
ocean model submitted by Zhang (Figure 3) still shows the September ice edge further north than in 2009.
The task team will also coordinate with the U.S. CLIVAR Decadal Predictability Working Group as well as the CLIVAR Working Group
on Ocean Model Development and CLIVAR Global Synthesis and Observational Panel.
The researchers plugged that trash census data
into ocean models, which simulate the circulation of the world's waters.
The Finnish Meteorological Institute has been participating in a model inter-comparison, which estimates how global
ocean models respond to the changes in wind in the Southern Ocean.
Brydon, D., S. Sun, and R. Bleck, 1999: A new approximation of the equation of state for sea water, suitable for
numerical ocean models.
Multiple sea - ice states and abrupt MOC transitions in a general
circulation ocean model Link (2013) DOI 10.1007 / s00382 -012-1546-2 (7 - 8): 1803 - 1817
Brown University researchers have made a key insight into how high - resolution
ocean models simulate the dissipation of turbulence in the global ocean.
The team calculated the change in the amount of heat entering the ocean using a state - of - the - art high resolution
ocean model developed and run by NOC scientists that is driven by surface observations.
And a few months ago, a study with a high - resolution
ocean model appeared, suggesting that the meltwater from Greenland is likely to weaken the AMOC considerably within a few decades (Böning et al. 2016 — as we reported).
Incorporate mesoscale eddy - resolving
ocean models more fully into the toolkit used for AMOC mechanisms / prediction studies, including long coupled GCM simulations, in order to address questions about the role of turbulence in controlling AMOC.
«By using pre-existing
ocean model output we can estimate which areas could potentially be affected over weekly to monthly timescales, and quickly at low computing cost.
