ADCP Measurements of Momentum Balance and Dynamic Topography in a Constricted Tidal Channel
Publisher: American Meteorological Society
Abstract: The dynamics of tidal flow through inlets are not fully understood; observations are scarce because of the small spatial scales over which the flow varies. This paper gives the first detailed measurements of the 2D structure ...
Long Barotropic Waves Generated by a Storm Crossing Topography
Publisher: American Meteorological Society
Abstract: Storms crossing topography are shown to radiate long surface gravity waves. The waves are transients generated by changes in the depth-dependent amplitude of the atmospherically forced pressure wave beneath a storm. This ...
Oscillating Barotropic Currents along Short Channels
Publisher: American Meteorological Society
Abstract: Intuitively, the transport of an oscillating flow in a short channel should be constrained to be approximately the same at all cross sections; that is, the transport is nondivergent. This intuitive constraint is quantified ...
Observations of the Phase of Tidal Currents along a Strait
Publisher: American Meteorological Society
Abstract: currents along this same length. This phase change supports the general result developed by Vennell, which states that the phase of the cross-sectional average velocity is approximately constant along a ?short? strait of variable cross-sectional area...
Observation of a Fast Continental Shelf Wave Generated by a Storm Impacting Newfoundland Using Wavelet and Cross-Wavelet Analyses
Publisher: American Meteorological Society
Abstract: Wavelet and cross-wavelet power spectra of sea level records from tide gauges along the Atlantic coast of Canada showed a low-frequency barotropic response after Hurricane Florence crossed the Newfoundland shelf in September ...
Prediction of Coastal Far Infragravity Waves from Sea-Swell Spectra
Publisher: American Society of Civil Engineers
Abstract: Far infragravity waves (FIGWs) with periods of 2–64 min can reduce the underkeel clearance for vessels in transit to ports and cause resonance in and around harbors and bays that amplifies low-frequency current flows. Sea ...
High Resolution Observations of an Outer-Bank Cell of Secondary Circulation in a Natural River Bend
Publisher: American Society of Civil Engineers
Abstract: Secondary circulation is a mechanism that increases vertical exchange between the horizontal layers in open channels. Vertical shear in curved flows induces secondary circulation in the plane normal to the primary flow ...

Coastal Flows Driven by Alongshore Density Gradients
Publisher: American Meteorological Society
Abstract: In this note we study the effect of an alongshore density gradient in driving the near-coastal circulation and determining the direction of the alongshore flow. We revisit and extend the results obtained by Malanotte-Rizzoli ...
The Influence of a Steady Baroclinic Deep Ocean On the Shelf: The Vertically Well-Mixed Case
Publisher: American Meteorological Society
Abstract: Many coastal regions in the world ocean are characterized by well-mixed conditions to shelf depth in the density field during the winter season. In these situations it is appropriate to construct a model based on the ...
