Multidecadal Mobility of the North Atlantic Oscillation

North Atlantic Multidecadal SST Oscillation: External forcing versus internal variability

Climate impacts of the Atlantic Multidecadal Oscillation

[1] The Atlantic Multidecadal Oscillation (AMO) is a near-global scale mode of observed multidecadal climate variability with alternating warm and cool phases over large parts of the Northern Hemisphere. Many prominent examples of regional multidecadal climate variability have been related to the AMO, such as North Eastern Brazilian and African Sahel rainfall, Atlantic hurricanes and North Amer...

The central role of ocean dynamics in connecting the North Atlantic Oscillation 1 to the Atlantic Multidecadal Oscillation

On the physics of the Atlantic Multidecadal Oscillation

The Atlantic Multidecadal Oscillation (AMO) is a pronounced signal of climate variability in the North Atlantic sea-surface temperature field. In this paper, we propose an explanation of the physical processes responsible for the timescale and the spatial pattern of the AMO. Our approach involves the analysis of solutions of a hierarchy of models. In the lowest member of the model hierarchy, wh...

Predictability of North Atlantic Multidecadal Climate Variability

Atmospheric weather systems become unpredictable beyond a few weeks, but climate variations can be predictable over much longer periods because of the coupling of the ocean and atmosphere. With the use of a global coupled ocean-atmosphere model, it is shown that the North Atlantic may have climatic predictability on the order of a decade or longer. These results suggest that variations of the d...
