Dynamics of large-amplitude geostrophic flows over bottom topography
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...
The nonlinear dustgrain-charging on large amplitude electrostatic waves in a dusty plasma with trapped ions
nonlinear dustgrain-charging large amplitude electrostatic waves dusty plasma trapped ions
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 ...
Remarks on the parallel propagation of small-amplitude dispersive Alfvénic waves
parallel propagation small-amplitude dispersive Alfvénic waves
2009/11/13
The envelope formalism for the description of a small-amplitude parallel-propagating Alfvén wave train is tested against direct numerical simulations of the Hall-MHD equations in one space dimension w...
The small amplitude of density turbulence in the inner solar wind
small amplitude density turbulence inner solar wind
2009/11/11
Very Long Baseline Interferometer (VLBI) observations were made of radio sources close to the Sun, whose lines of sight pass through the inner solar wind (impact parameters 16-26 RE). Power spectra we...
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...
Nonlinear instability and sensitivity of a theoretical grassland ecosystem to finite-amplitude perturbations
Nonlinear instability theoretical grassland ecosystem finite-amplitude perturbations
2009/11/3
Within a theoretical model context, the sensitivity and instability of the grassland ecosystem to finite-amplitude perturbations are studied. A new approach of conditional nonlinear optimal perturbati...
Conjugate flows and amplitude bounds for internal solitary waves
Conjugate flows amplitude bounds internal solitary waves
2009/10/30
Amplitude bounds imposed by the conservation of mass, momentum and energy for strongly nonlinear waves in stratified fluid are considered. We discuss the theoretical scheme which allows to determine b...
