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: The phase of the M2 surface elevation tide changes by 100° along a 40-km length of Cook Strait, New Zealand. Acoustic Doppler Current Profiler measurements are presented that show a change of only 12° in the phase of ...
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 ...
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 ...
Divergence-Free Spatial Velocity Flow Field Interpolator for Improving Measurements from ADCP-Equipped Small Unmanned Underwater Vehicles
Publisher: American Meteorological Society
Abstract: pplying a two-dimensional (2D) divergence-free (DF) interpolation to a one-person deployable unmanned underwater vehicle?s (UUV) noisy moving-vessel acoustic Doppler current profiler (MV-ADCP) measurements improves the ...
