Long waves over a bi-viscous seabed:transverse patterns
Long waves bi-viscous seabed transverse patterns
2009/11/12
The coupled interaction of long standing hydrodynamic waves with a deformable non-Newtonian seabed is examined using a two-layer model for which the upper layer fluid is inviscid and the lower layer i...
Observational and Numerical Evidence for Wind-Forced Coastal Trapped Long Waves
Wind-Forced Coastal Trapped Long Waves Numerical Evidence
2009/3/7
Recent work has shown that the linear, wind-forced quasi-geostrophic motion of stratified water over shelf topography can be described by a sum of modes, the amplitude of each of these modes satisfyin...
Annual Forcing of Baroclinic Long Waves in the Tropical North Pacific Ocean
bathythermograph Tropical North Pacific Ocean Baroclinic Long Waves
2009/3/7
From an analysis of the bathythermograph (BT) data files for the entire tropical North Pacific Ocean, the annual vertical displacement in the main thermocline from 10°−20°N is observed to propag...
Propagating Long Waves on Oceanic Density Fronts：An Analytic Model
Propagating Long Waves Oceanic Density Fronts Analytic Model
2009/1/21
An analytic model of long, propagating free-wave perturbations to an established upper ocean density front is developed. The primary purpose of the model is to illuminate basic frontal wave mechanisms...
The coastally trapped long-wave theory is adapted to a double shelf bottom topography in the development of a barotropic long-wave model for calculating wintertime wind-driven currents and sea level f...
Finite-Amplitude Long Waves on Coastal Currents
Finite-Amplitude Long Waves Coastal Currents
2008/12/27
Two models of coastal currents are described that allow fully nonlinear wavelike solutions for the limit of long waves. The first model is an adaptation of a model used by Yi and Warn for finite-ampli...
Topographic Filtering and Reflectionless Transmission of Long Waves
Topographic Filtering Reflectionless Transmission Long Waves
2008/11/11
The equation governing the passage of linear monochromatic, long waves over variable topography can be transformed into a Schrödinger equation. There are several transformations accomplishing thi...
A model is developed to explain the observation made in several laboratory experiments that short wind-generated waves are suppressed by a train of long, mechanically generated waves. A sheltering mec...
