Structure of the Baroclinic Tide Generated at Kaena Ridge, Hawaii
Repeat transects of full-depth density and velocity are used to quantify generation and radiation of the semidiurnal internal tide from Kaena Ridge, Hawaii. A 20-km-long transect was sampled every 3 h using expendable current profilers and the absolute velocity profiler. Phase and amplitude of the baroclinic velocity, pressure, and vertical displacement were computed, as was the energy flux. La...
متن کاملLee Waves and Mountain Waves ∗
Buoyancy perturbations develop when stably stratified air ascends a mountain barrier. These perturbations often trigger disturbances that propagate away from the mountain as gravity (or buoyancy) waves. Gravity waves triggered by the flow over a mountain are referred to as mountain waves or lee waves. Mountain waves sometimes reveal their presence through dramatic cloud formations, such as smoo...
متن کاملLarge Amplitude Breaking Internal Waves: Their Origin and Dynamics
Our objectives are to use both acoustic remote sensing and in situ profile observations of large amplitude internal waves, together with highly resolved numerical simulation, so as to develop a predictive understanding of their behavior, with application to their generation by flow past topography, their contribution to mass and momentum transport, mixing, modulation of near surface bubble clou...
متن کاملIntrinsic Breaking of Internal Solitary Waves in a Deep Lake
Based on simulations with the Dubreil-Jacotin-Long (DJL) equation, the limiting amplitude and the breaking mechanisms of internal solitary waves of depression (ISWs) are predicted for different background stratifications. These theoretical predictions are compared to the amplitude and the stability of the leading internal solitary waves of more than 200 trains of ISWs observed in the centre of ...
متن کاملBreaking of Super-Critically Incident Internal Waves at a Sloping Bed
A laboratory experiment was carried out to investigate the mixing on a sloping bed caused by a localised ray of internal waves breaking with super-critical frequencies. Previous work has shown that for near critical waves the turbulent boundary layer was confined to a thin region just above the bed. As a result, relatively small overturning turbulent lengthscales were observed. On the other han...
