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 ...
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 ...
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 ...
Marine-based multiproxy reconstruction of Atlantic multidecadal variability
(WileyAmerican Geophysical Union, 2014-02-28)
Atlantic multidecadal variability (AMV) is known to impact climate globally, and knowledge about the persistence of AMV is important for understanding past and future climate variability, as well as modeling and assessing ...
Thermodynamic controls of the Atlantic Niño
(Nature Publishing Group (NPG), 2015-11-26)
Prevailing theories on the equatorial Atlantic Niño are based on the dynamical interaction between atmosphere and ocean. However, dynamical coupled ocean-atmosphere models poorly simulate and predict equatorial Atlantic ...
Decadal prediction of Sahel rainfall: where does the skill (or lack thereof) come from?
(Springer, 2016-12)
Previous works suggest decadal predictions of Sahel rainfall could be skillful. However, the sources of such skill are still under debate. In addition, previous results are based on short validation periods (i.e. less than ...
