REPORTS 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.

| Summary: | 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 dominant multidecadal sea surface temperature patterns in the North Atlantic, which have been associated with changes in climate over Eurasia, can be predicted if an adequate and sustainable system for monitoring the Atlantic Ocean exists. Historical data for sea surface temperatures (SSTs) indicate that the North Atlantic has experienced significant multidecadal climate variability superimposed on a positive trend (1, 2). It has been shown (3) that a yearly to decadal time scale propagation of SST anomalies may be traced in the surface |
