Variations of Kuroshio Intrusion and Internal Waves at Southern East China Sea

Abstract

My long-term scientific goals are to understand the dynamics and identify mechanisms of small-scale processes- i.e., internal tides, inertial waves, NLIWs, and turbulence mixing- in the ocean and thereby help develop improved parameterizations of mixing for ocean models. Mixing within the stratified ocean is a particular focus as the complex interplay of internal waves from a variety of sources and turbulence makes this a current locus of uncertainty. For this proposal, my broad focus is on small-scale processes (NLIWs and inertial waves), internal tides, and cold water intrusions generated as the Kuroshio and barotropic tides interact with the continental shelf of the East China Sea (ECS) and with one prominent submarine ridge (I-Lan Ridge) (Fig. 1). These small scale processes modulate the temporal, horizontal and vertical spatial structures of temperature in the ocean, and therefore may significantly modify oceanic acoustics properties and introduce uncertainty on sonar performance and acoustic propagation.
