The variability of the large-amplitude internal wave field on the Australian North West Shelf
Internal waves Solitary waves Internal tide Continental slope Australian North West Shelf (14–221S, 114–1261E)
2015/6/30
Observations are presented of large-amplitude internal waves (LAIWs) generated by the steepening of the internal tide on the Australian North West Shelf (NWS) over a 4-month period extending from stro...

2011/9/28
Only for very few beta Cephei stars has the behaviour of the magnetic field been studied over the rotation cycle. During the past two years we have obtained multi-epoch polarimetric spectra of the bet...

2010/11/11
Context. The investigations of the photometric and spectral variability of PMS stars are essential to a better understanding of the early phases of stellar evolution. We are carrying out a photometric...
The modified Korteweg-de Vries equation in the theory of large-amplitude internal waves
modified Korteweg-de Vries equation theory of large-amplitude internal waves
2009/11/13
The propagation of large- amplitude internal waves in the ocean is studied here for the case when the nonlinear effects are of cubic order, leading to the modified Korteweg - de Vries equation. The co...

large-amplitude geostrophic flows bottom topography
2009/11/13
We examine the interaction of near-surface and near- bottom flows over bottom topography. A set of asymptotic equations for geostrophic currents in a three-layer fluid is derived. The depths of the ac...

2009/11/13
The nonlinear dustgrain-charging and the influence of the ion density and temperature on electrostatic waves in a dusty plasma having trapped ions are investigated by numerical calculation. This work ...
Large amplitude solitary waves in and near the Earth’s magnetosphere,magnetopause and bow shock:Polar and Cluster observations
Large amplitude solitary waves Earth’s magnetosphere magnetopause bow shock
2009/11/11
Solitary waves with large electric fields (up to 100's of mV/m) have been observed throughout the magnetosphere and in the bow shock. We discuss observations by Polar at high altitudes ( ~ 4-8 RE ), d...
On the nonexistence of large amplitude stationary solitary waves in symmetric unmagnetized pair plasmas
large amplitude stationary solitary waves symmetric unmagnetized pair plasmas
2009/11/11
Waves in pair plasmas have a fundamentally different dispersion due to the equal charge-to-mass ratios between negative and positive charges. In view of possible applications e.g. to electron-positron...

2009/11/2
This paper deals in a consistent way with the implications, for the existence of large amplitude stationary structures in general plasmas, of assuming strict charge neutrality between electrons and io...
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...
