Time-Variable Refraction of the Internal Tide at the Hawaiian Ridge
The interaction of the dominant semidiurnalM2 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 theHawaiianRidge. The background fields are taken from the SimpleOceanDataAssimilation (SODA) ocean analysis, at 2-month intervals from 1992 through 2001. Tides are computed with the ...
متن کاملInternal Tides and Turbulence along the 3000-m Isobath of the Hawaiian Ridge
Full-depth velocity and density profiles taken along the 3000-m isobath characterize the semidiurnal internal tide and bottom-intensified turbulence along the Hawaiian Ridge. Observations reveal baroclinic energy fluxes of 21 5 kW m 1 radiating from French Frigate Shoals, 17 2.5 kW m 1 from Kauai Channel west of Oahu, and 13 3.5 kW m 1 from west of Nihoa Island. Weaker fluxes of 1–4 2 kW m 1 ra...
متن کاملa numerical study of internal tide generation due to interaction of barotropic tide with bottom topography in the oman gulf
a major part of tidal energy is usually dissipated by the interaction of tidal currents with bottom topography. gulf of oman is a marginal sea which has variable topography and its dominant tidal constituent is m2 semi-diurnal tide. in this paper, the interaction of barotropic tidal current with bottom topography is evaluated. this phenomenon causes the formation of internal tide. internal tide...
متن کاملFrom tides to mixing along the Hawaiian ridge.
The cascade from tides to turbulence has been hypothesized to serve as a major energy pathway for ocean mixing. We investigated this cascade along the Hawaiian Ridge using observations and numerical models. A divergence of internal tidal energy flux observed at the ridge agrees with the predictions of internal tide models. Large internal tidal waves with peak-to-peak amplitudes of up to 300 met...
متن کاملIncoherent Nature of M2 Internal Tides at the Hawaiian Ridge
Moored current, temperature, and conductivity measurements are used to study the temporal variability of M2 internal tide generation above the Kaena Ridge, between the Hawaiian islands of Oahu and Kauai. The energy conversion from the barotropic to baroclinic tide measured near the ridge crest varies by a factor of 2 over the 6-month mooring deployment (0.5–1.1 W m). The energy flux measured ju...
