Assimilation of Ship-Mounted ADCP Data for Barotropic Tides: Application to the Ross Sea
Publisher: American Meteorological Society
Abstract: The application of a generalized inverse approach for assimilating vessel-mounted acoustic Doppler current profiler (VM-ADCP) data into numerical solutions of barotropic tides is described. The derived estimates of tidal ...
Time-Variable Refraction of the Internal Tide at the Hawaiian Ridge
Publisher: American Meteorological Society
Abstract: he interaction of the dominant semidiurnal M2 internal tide with the large-scale subtidal flow is examined in an ocean model by propagating the tide through an ensemble of background fields in a domain centered on the ...
Deviation of Long-Period Tides from Equilibrium: Kinematics and Geostrophy
Publisher: American Meteorological Society
Abstract: New empirical estimates of the long-period fortnightly (Mf) tide obtained from TOPEX/Poseidon (T/P) altimeter data confirm significant basin-scale deviations from equilibrium. Elevations in the low-latitude Pacific have ...
Efficient Inverse Modeling of Barotropic Ocean Tides
Publisher: American Meteorological Society
Abstract: A computationally efficient relocatable system for generalized inverse (GI) modeling of barotropic ocean tides is described. The GI penalty functional is minimized using a representer method, which requires repeated solution ...
The Global S1 Tide
Publisher: American Meteorological Society
Abstract: The small S1 ocean tide is caused primarily by diurnal atmospheric pressure loading. Its excitation is therefore unlike any other diurnal tide; in particular, pressure loading is maximum near the equator where the diurnal ...
Estimating Open-Ocean Barotropic Tidal Dissipation: The Hawaiian Ridge
Publisher: American Meteorological Society
Abstract: The generalized inverse of a regional model is used to estimate barotropic tidal dissipation along the Hawaiian Ridge. The model, based on the linear shallow-water equations, incorporates parameterizations for the dissipation ...
The M2 Internal Tide off Oregon: Inferences from Data Assimilation
Publisher: American Meteorological Society
Abstract: A linearized baroclinic, spectral-in-time tidal inverse model has been developed for assimilation of surface currents from coast-based high-frequency (HF) radars. Representer functions obtained as a part of the generalized ...
