In this talk, I will review multi-scaled circulation variability observed in the major current systems in the Northwestern Pacific Ocean, namely, the North Equtorial Current (NEC), the Subtropical Countercurrent (STCC), and the Kuroshio/Kuroshio Extension (KE). Rather than regarding these 3 current variations as independent features, I will focus on their commonality, their inter-connections, and their impact. In addition to its forced variability by the atmosphere, I will stress the role by the decadal KE variability on the overlying atmosphere. The overall message is that there is a need to explore and understand the northwestern Pacific Ocean circulation variability as an integrated climate system.
Bo Qiu is a Professor at the Department of Oceanography, University of Hawaii at Manoa. He received his B.Sc., M.Sc. and PhD degrees in Physical Oceanography from Kyoto University. His scientific interests include large-scale ocean circulation variability, mid-latitude air-sea interaction, geophysical fluid dynamics, and satellite oceanography. He has published more than 180 articles in peer-reviewed journals and was a contributing author to both IPCC 4th and 5th Assessment Reports. Prof. Qiu is recipients of the Okada Prize from the Oceanographic Society of Japan (1993), the New Investigators Award from NASA (1996), the University of Hawaii Board of Regents' Medal for Excellence in Research (2018), the Japan Oceanographic Society Prize (2019), Fellow of American Meteorological Society (AMS, 2021), and the Henry Stommel Research Medal from AMS (2021).
