摘　　要：中国科学院西太平洋科学观测网实现了对西太平洋深层西边界流的长期连续和组网观测。基于观测网获取的数据并结合模式数据,逐步摸清了深层西边界流在雅浦—马里亚纳海沟连接区季节性入侵西太平洋的路径、流量和动力机制,揭示了地形罗斯贝波引起的深层季节内振荡特征和能量来源,发现了深海与上层海洋和气候变化联系的"高速公路",改变了以往"深海是死水、杂乱无章和非常缓慢变化"的传统认知,就该方面的创新进展进行了总结,并讨论了下一步太平洋深层环流的观测和研究设想。The Scientific Observing Network of the Chinese Academy of Sciences has realized the longterm mooring measurements of the Deep Western Boundary Current(DWBC)in the western Pacific Ocean.Based on observational data and numerical model outputs,we have illustrated the pathway,volume transport,and forcing mechanism for the seasonal intrusion of the DWBC at the Yap-Mariana Junction,revealed the characteristics and energy sources of deep intraseasonal oscillation induced by the topographic Rossby wave and found "a high-speed way" connecting the DWBC to the upper ocean processes and climate change. These new findings have changed the traditional view that the deep ocean circulation is in a state of calm,disorder,and a very slow variation. This paper summarizes the recent advances in the DWBC in the western Pacific Ocean,and discusses the prospect of observation and scientific study of the Pacific DWBC.
