PO53D:
Observing and Predicting Historic and Future Surface and Internal Tides I


Session ID#: 7875

Session Description:
The gravitational pull of the sun and the moon causes predictable but fascinating surface tidal motions in the world’s oceans. However, non-astronomical events such as sea-level rise, bathymetric change, non-tidal currents, and altered stratification also produce changes to tidal signals, over time scales ranging from meteorological events to millennia.  This session seeks contributions that encompass seasonal and secular variability of surface and internal tides in the open and coastal ocean, as well as shorter time-scale processes such as topographic scattering effects and internal tide/mesoscale circulation interactions. We invite both observation- and model-based studies of the processes leading to non-stationary tides and application-based studies focused on tidal prediction and satellite altimetry. Changed tidal dynamics can also imply altered long-wave dynamics. Hence, we also encourage contributions that explore the connections between narrow-band tidal dynamics and broadband phenomena such as storm surges.
