Possible impacts of the tripolar SST anomalies on the decadal scale variability of the North Atlantic climate are also discussed. The dominant mod e of the North Atlantic wintertime SST variability exhibits a meridional tri-polar pattern, with a colder subpolar region, a warmer midlatitudes, and a colder region between the equator and 30°N. Validations on the model performance show that the BCM reproduces the observed NAO pattern and the tri-polar like SST vari ability mode successfully.
