The Effect of Internal Wave Strain on Vertical Spectra of Fine-Structure
Publisher: American Meteorological Society
Abstract: Vertical spectra of temperature perturbations are due to (i) internal wave displacement in the mean profile and (ii) fine-structure that would still be measured in the absence of internal waves. The former is probably ...
Topographic Rossby Waves off East Australia: Identification and Role in Shelf Circulation
Publisher: American Meteorological Society
Abstract: Hamon et al.(1975) analyzed two years of surface current data from ships' set along two tracks parallel to 560 km of the east Australian shelf and found a phase lag of 10 days between long (120 day) period current fluctuations ...
On the Parameterization of Diapycnal Fluxes due to Double-Diffusive Intrusions
Publisher: American Meteorological Society
Abstract: An attempt is made to Parameterized the large-Scale average diapycnal (cross-isopycnal) mixing that presumably occurs in the thermohaline fronts that develop when large-scale epipycnal (along-isopycnal) gradients of T and ...
On Spindown in the Ocean Interior
Publisher: American Meteorological Society
Abstract: In a rotating gratified fluid, with small Ekman number E and Rossby number Ro, vertical diffusion of momentum is balanced by local deceleration for large values of the Burger number S, and hence leads to an increase in S. ...
Internal Wave Spectra in the Presence of Fine-Structure
Publisher: American Meteorological Society
Abstract: Phillips has shown that an undulating motion of a layered medium relative to a measuring instrument will result in a σ?2 spectrum (frequency or wavenumber) over a bandwidth determined by the thickness of the layers and of ...
Predicting Changes in Tidal Regime: The Open Boundary Problem
Publisher: American Meteorological Society
Abstract: Attempts to predict the impact on a tidal regime of large engineering structures are generally based on the use of a numerical model which is calibrated to reproduce the natural tidal regime and then rerun with the structures ...
The Transfer of Energy and Momentum by the Wind to the Surface Mixed Layer
Publisher: American Meteorological Society
Abstract: During the initial stages of the deepening of the surface mixed layer, the rate of increase of potential energy is proportional to the input of energy to the mixed layer by the wind. In an attempt to reconcile an apparent ...
Dynamical Aspects of the Flow Through the Strait of Belle Isle
Publisher: American Meteorological Society
Abstract: We present an analysis of 50 days of current meter and sea Revel data collected in a long narrow strait connecting the Gulf of St. Lawrence to the Atlantic Ocean. The dynamical balances implied by a scale analysis of the ...
A Variable-Depth Green's Function for Shelf Edge Tides
Publisher: American Meteorological Society
Abstract: The Green's function for a semi-infinite ocean with depth a function of distance from the boundary is developed numerically for the M2 frequency and with Coriolis frequency and depth profile appropriate to the continental ...
Implications for Ocean Mixing of Internal Wave Scattering off Irregular Topography
Publisher: American Meteorological Society
Abstract: Earlier work has suggested that internal wave reflection off sloping bottoms may cause significant diapycnal mixing in the deep ocean, and may also represent an important sink of internal wave energy. Most theories have ...
