Linear stability or occurrence of an exchange of stability is studied for interfacial solitary waves propagating in a two-layer fluid. We find that an exchange of stability occurs at every stationary value of the total energy of the solitary waves. Then, we construct a general criterion for the...
The stability of finite amplitude, two-dimensional solitary waves of permanent form in water of uniform depth with respect to two-dimensional infinitesimal disturbances is investigated. It is numerically confirmed that the recent analytical results obtained by Saffman for the 'superharmonic' instability of...
We found large-amplitude nonlinear internal solitary waves at the end of April and they propagated to the southwest paralleling with the isobaths in this area. They probably resulted from the local shelf break and were rarely observed in SAR data. 展开 关键词: 南海 文昌 内孤立波 现场观测 斜...
By using nonlinear perturbation method a time-dependent equation is derived which governs internal waves in stratified fluids of great depth. The resultant... ONO,Hiroaki - 《Journal of the Physical Society of Japan》 被引量: 659发表: 1975年 The stability of internal solitary waves A theory is...

Based on the temperature data recorded by a mooring system deployed in the northern South China Sea (SCS), this study compares the traditional methods of identifying and extracting internal solitary waves (ISWs): the whole water column isotherm (WCI) method and the single isotherm (SI) method,...
After a review of the existing state of affairs, an improvement is made in the stability theory for solitary-wave solutions of evolution equations of Korteweg-de Vries-type modelling the propagation of small-amplitude long waves. It is shown that the bulk of the solution emerging from initial ...
We propose that internal solitary waves (ISWs) induced by tides can produce an effective, unidirectional boundary “current” that forms asymmetric sand waves. We test this idea by examining a sand-wave field off the Messina Strait, where we hypothesize that ISWs formed at the interface between...
The structure and stability of mode-2 internal solitary-like waves is investigated experimentally. A rank-ordered train of mode-2 internal solitary waves is generated using a lock release configuration. The pycnocline is centred either on the mid-depth of the water column (the 0% offset case) ...
摘要: The stability of the solitary kinetic Alfvén wave is investigated. In the one-dimensional fully nonlinear case the wave is shown to be stable against perturbations in the amplitudes.关键词: Magnetohydrodynamic Stability Magnetohydrodynamic Waves Plasma Physics Solitary Waves Electric Fields Kinetic...
