Quantization super fluid dynamics fluid vortex dynamics
2014/12/18
Dynamics of quantized vortex lines in a superfluid feature symmetries associated with the geometric character of the complex-valued field, w(z)=x(z)+iy(z), describing the instant shape of the line. Al...
The interaction of Kelvin waves and the non-locality of the energy transfer in superfluids
Kelvin waves energy transfer
2010/4/7
We argue that the physics of interacting Kelvin Waves (KWs) is highly non-trivial and cannot be understood on the basis of pure dimensional reasoning. A consistent theory of KW turbulence in superflui...

2009/11/9
Kelvin waves excited by tropospheric convection are considered to be one of the main drivers of the stratospheric quasi-biennial oscillation (QBO). In this paper we combine several measured data sets ...
Wave fluxes of equatorial Kelvin waves and QBO zonal wind forcing derived from SABER and ECMWF temperature space-time spectra
Wave fluxes equatorial Kelvin waves QBO zonal wind forcing SABER
2009/6/22
The quasi-biennial oscillation (QBO) of the zonal mean zonal wind is a dynamical phenomenon of the tropical middle atmosphere. Influences of the QBO can even be found at mid and high latitudes. It is ...
A simple nonlinear model of the generation of Kelvin waves is presented and applied to internal Kelvin waves in Lake Michigan. It is shown that a Kelvin wave which has a wavelength longer than the Ros...
Coastal Upwelling and Kelvin Waves with Small Longshore Topography
Coastal Upwelling Kelvin Waves Small Longshore Topography
2009/2/23
A simple, uniformly stratified, linear model is developed to examine the effects on upwelling and internal Kelvin wave propagation of small, slow, longshore varying topography and coastline. The condi...
Observations of Internal Kelvin Waves Trapped Round Bermuda
Internal Kelvin Waves Trapped Round Bermuda
2009/2/18
Observations of the vertical and horizontal structure of motions near Bermuda have been made with two long-term moored arrays, one relatively far from and the other close to the island. Although not c...
Topographic Coupling of Surface and Internal Kelvin Waves
Topographic Coupling Surface Internal Kelvin Waves
2009/2/18
An analytical method is developed to compute the diffraction of a barotropic Kelvin wave by a localized topographic irregularity on an otherwise flat-bottom ocean with an arbitrary vertical stratifica...
An analytic theory is presented for free, barotropic Kelvin waves subject to constant, vertical eddy viscosity on a semi-infinite, f-plane shelf of constant depth bordering a straight, vertical coast....
Wind-Generated Equatorial Kelvin Waves Observed Across the Pacific Ocean
Sea-level fluctuations Zonal winds Pacific Ocean low-mode Kelvin waves
2009/2/6
Sea-level fluctuations during 1978–80 at equatorial Pacific islands separated by as much as one-quarter of the earth's circumference are coherent at periods of 1–6 weeks with phases implying eastward ...
On Vertically Propagating Coastal Kelvin Waves at Low Latitudes
internal Kelvin waves Low Latitudes
2009/2/5
Vertically propagating coastal internal Kelvin waves (IKWs) forward by the alongshore component of the wind at the coast are studied, utilizing an f-plane model of a continuously stratified ocean with...
The effect of a mean current on Kelvin waves is considered, including the case when the current is not in geostrophic balance. Because the problem is non-separable, a perturbation scheme is developed ...
Internal Kelvin Waves Generated by Quasi-Periodic Mesoscale Motion along the Coast
Internal Kelvin Waves Quasi-Periodic Mesoscale Motion Coast
2009/1/16
In a two-layer model with a rigid surface and a flat bottom on an f-plane, an internal Kelvin wave is forced by quasi-geostrophic, mesoscale meanders of a coastal current. These meanders are assumed t...

Buoyancy Forces Kelvin Waves
2009/1/13
The early stages of the adjustment of an ocean toward equilibrium is examined using an ocean general circulation model. The initial state is one with uniform meridional potential temperature gradients...

Equatorial Kelvin Waves Realistically Sheared Zonal Currents
2009/1/13
We investigate the interaction of baroclinic equatorial Kelvin waves with realistically sheared background zonal currents in a linearized, continuously stratified model. The background flows are in th...
