Variations of Kuroshio Intrusion and Internal Waves at Southern East China Sea: Observational Study with Lagrangian Float and Mooring ADCPs; Final technical rept. 1 Dec 2006-31 Mar 2008

摘要

The PI attended three ONR workshops to discuss and help define the future integrated observational program for 'Quantifying, Predicting and Exploiting Uncertainty (QPEU)', i.e., to help formulate an experiment to study the Kuroshio intrusion, nonlinear internal waves (NLIWs), internal tides, inertial waves, and turbulence mixing resulting from the Kuroshio-topography interaction. Using historical CTD data collected by the National Center for Ocean Research (NCOR) between 1985 and 2002, the PI computed the fluctuations of sound speed in different regions along the Kuroshio path and across the continental shelf and slope. Preliminary analysis concludes that strong sound speed anomalies are induced by NLIWs, internal tides, and processes associated with the Kuroshio interaction with the continental slope and shelf. Such sound speed anomalies have the temporal and spatial scales and characteristics associated with the corresponding oceanic processes.
