Arctic sea ice and Eurasian climate: A review
(Science Press, 2014-11-28)
The Arctic plays a fundamental role in the climate system and has shown significant climate change in recent decades, including the Arctic warming and decline of Arctic sea-ice extent and thickness. In contrast to the ...
Multiple timescales of stochastically forced North Atlantic Ocean variability: A model study
(Springer, 2015-09)
The Atlantic meridional overturning circulation (AMOC) and the subpolar gyre (SPG) are important elements in mechanisms for multidecadal variability in models in the North Atlantic Ocean. In this study, a 2000-year long ...
North Atlantic multi-decadal variability - mechanisms and predictability
(World Scientific Publishing, 2015-10)
The North Atlantic Ocean undergoes pronounced basin-wide, multi-decadal variations. The corresponding fluctuations in sea surface temperature (SST) have become known as the Atlantic Multi-decadal Oscillation (AMO) or ...
Uncertainty in twenty-first century projections of the Atlantic Meridional Overturning Circulation in CMIP3 and CMIP5 models
(Springer, 2016-05-26)
Uncertainty in the strength of the Atlantic Meridional Overturning Circulation (AMOC) is analyzed in the Coupled Model Intercomparison Project Phase 3 (CMIP3) and Phase 5 (CMIP5) projections for the twenty-first century; ...
Role of atmosphere-ocean interactions in supermodeling the tropical Pacific climate
(AIP Publishing, 2017-12-29)
The supermodel strategy interactively combines several models to outperform the individual models comprising it. A key advantage of the approach is that nonlinear improvements can be achieved, in contrast to the linear ...
Resolving the upper-ocean warm layer improves the simulation of the Madden-Julian oscillation
(Springer, 2014-09)
Here we show that coupling a high-resolution one-column ocean model to an atmospheric general circulation model dramatically improves simulation of the Madden–Julian oscillation (MJO) to have realistic strength, period, ...
The impact of mean state errors on equatorial Atlantic interannual variability in a climate model
(American Geophysical Union, 2015-02-23)
Observations show that the Equatorial Atlantic Zonal Mode (ZM) obeys similar physics to the El Niño Southern Oscillation (ENSO): positive Bjerknes and delayed negative feedbacks. This implies the ZM may be predictable on ...
Dynamically combining climate models to "supermodel" the tropical Pacific
(Wiley, 2016-01)
We construct an interactive ensemble of two different climate models to improve simulation of key aspects of tropical Pacific climate. Our so-called supermodel is based on two atmospheric general circulation models (AGCMs) ...
Seasonal-to-decadal predictions with the ensemble kalman filter and the Norwegian earth System Model: A twin experiment
(Co-Action Publishing, 2014-03-10)
Here, we firstly demonstrate the potential of an advanced flow dependent data assimilation method for performing seasonal-to-decadal prediction and secondly, reassess the use of sea surface temperature (SST) for initialisation ...
The Madden-Julian Oscillation in a warmer world
(Wiley, 2015-07)
Global warming's impact on the Madden-Julian Oscillation (MJO) is assessed using one of the few models capable in reproducing its key features. In a warmer climate predicted for the end of the century, the MJO increases ...
