An Atlantic-driven rapid circulation change in the North Pacific Ocean during the late 1990s

Abstract Interbasin interactions have been increasingly emphasized in recent years due to their roles in shaping climate trends and the global warming hiatus in the northern hemisphere. The profound influence from the North Atlantic on the Tropical Pacific has been a primary focus. In this study, we...
