A model of decadal ocean-atmosphere interaction in the North Pacific basin

From a simple and a global coupled model, we showed that the tropical and e xtratropical ocean-atmosphere interactions and the teleconnection between t he tropics and extratropics in these interactions are responsible for the c o-variations of the decadal to interdecadal climate fluctuations in the tro pical and extratropical Pacific. The subtropical oceanic Rossby waves are f ound to play an important role in forming the coupled decadal to interdecad al mode. They are responsible for slow exchanges of mass and heat between t he tropical and subtropical ocean gyres that serve as an important oceanic linking bridge of the tropical and extratropical decadal to interdecadal oc ean-atmosphere interactions in the Pacific basin.
