Influence of the ocean on North Atlantic climate variability 1871-1999

From: Journal of Climate | Date: October 15, 2003| Author: | Copyright information

ABSTRACT

The influence of changing ocean conditions on the variability of climate in the North Atlantic region is studied by analyzing ensemble simulations with an atmospheric GCM forced with reconstructed sea surface temperature (SST) data for the period 1871-1999. The ocean influence on multidecadal variability is analyzed separately from the influence on interannual variability.

SST-forced variability on multidecadal timescales is shown to be dominated by a single mode that, in wintertime, resembles the North Atlantic Oscillation. The principal forcing for this mode is from variations in ...
