[A-OS08] ECS-Kuroshio and Ryukyu Current System -Observation, modeling and theory-

Wed. May 29, 2019 1:45 PM - 3:15 PM 105 (1F)

convener:Hirohiko Nakamura(Kagoshima University, Faculy of Fisheries), Xiao-Hua Zhu(Second Institute of Oceanography), Chairperson:Hirohiko Nakamura(Kagoshima University), Jae-Hun Park(Inha University)

The East China Sea (ECS) is separated from the North Pacific basin by the Ryukyu Islands. On each side of the Ryukyu Islands, there lies two western boundary currents -the Kuroshio on the northwest and the Ryukyu Current on the southeast. These two currents play an important role in the global substance cycle and have a remarkable impact on the climate and adjacent marginal seas. Our knowledge of the Kuroshio and the Ryukyu Current's dynamics, variability, and impact has advanced significantly over the last decade, because of recent international collaborative field programs, improvement in satellite measurements, and advancement in high-resolution numerical models. This session seeks contributions from ECS-Kuroshio and Ryukyu Current studies and will cover a wide range of topics of observation, modeling and theory. The dynamics of the Kuroshio and the Ryukyu Current's variability at all spatio-temporal scales, the influence of the Kuroshio on typhoons and climate, the interactions among the Kuroshio, Ryukyu Current and eddies, internal waves including near-internal waves and their interactions with background currents, and the water mass exchanges through the gaps between the Ryukyu Islands are welcome to be discussed in this session.
