PL53A:
Ocean Tides: From Planetary to Turbulent Scales II

Session ID#: 92689

Session Description:
This session welcomes talks on the observation and prediction of surface and internal tides on Earth or other planets. Tides impact many aspects of the ocean sciences. The dissipation of tidal energy may influence climate by driving vertical fluxes balancing deep-water formation at high latitudes. The associated mixing is also key for sustaining primary production in the ocean, and surface tides may drive evolutionary process near the coastal boundary where tidal ranges are large. Recently, the combination of accelerated sea-level rise and spring tides has resulted in “Sunny-weather flooding” in some coastal locations. While much progress has been made in predicting surface and internal tides in numerical models, internal tides are still more difficult to predict than surface tides because the relatively short-length scale internal tides are easily refracted and scattered by the mesoscale background flows. There is great potential to improve their predictability by assimilating observed mesoscale fields, improving gravity wave damping schemes, and increasing model resolution. Ultimately, this will benefit operational forecasting and allow for the removal of the tides from altimetry collected in the upcoming Surface Water Ocean Topography (SWOT) mission.
