Interaction between internal waves and multiple-scale dynamics

Session ID#: 27806

Session Description:
Internal waves in the ocean, including inertial internal waves, internal tides and nonlinear internal waves, co-exist with other oceanic phenomena with multiple-scales, such as general circulations, fronts, mesoscale and sub-mesoscale eddies. Since such phenomena have different temporal and spatial scales from internal waves, their dynamics have usually been studied separately. However, more and more evidences reveal apparent interactions between them. Background currents and tilted thermocline associated with geostrophic circulation or mesoscale eddies affect the generation and propagation of internal waves, including reflection, refraction, formation of higher modes and non-linear evolution. As a feedback, internal wave breaking or scattering changes local mixing, thus influencing the genesis and evolution of general circulation and mesoscale eddies. This feedback may be especially important for long-term variations of ocean circulation and climate change, and also provides a roadmap to understand and estimate appropriate dissipation rates for numerical models. This session invites presentations that report recent progress on interactions between internal waves and other dynamical phenomena in the ocean, so as to clarify the energy and momentum route between these processes in different scales. Observational, theoretical and numerical investigations are all welcome.
