Large amplitude dust-acoustic solitary waves and double layers in nonthermal warm complex plasmas
AIP Advances, 2023 Using a Sagdeev pseudo-potential approach, where the nonlinear structures are stationary in a comoving frame, the arbitrary or large amplitude dust-acoustic solitary waves and double layers have been studied in dusty plasmas containing warm positively ...

The effect of strong shear on internal solitary-like waves [PDF]
Nonlinear Processes in Geophysics, 2021 Large-amplitude internal waves in the ocean propagate in a dynamic, highly variable environment with changes in background current, local depth, and stratification. The Dubreil–Jacotin–Long, or DJL, theory of exact internal solitary waves can account for

Rossby Solitary Waves Generated by Wavy Bottom in Stratified Fluids
Advances in Mechanical Engineering, 2013 Rossby solitary waves generated by a wavy bottom are studied in stratified fluids. From the quasigeostrophic vorticity equation including a wavy bottom and dissipation, by employing perturbation expansions and stretching transforms of time and space, a ...

Fractional Theoretical Model for Gravity Waves and Squall Line in Complex Atmospheric Motion
Complexity, 2020 The evolution of nonlinear gravity solitary waves in the atmosphere is related to the formation of severe weather. The nonlinear concentration of gravity solitary wave leads to energy accumulation, which further forms the disastrous weather phenomenon ...

Bifurcation Phenomena of Nonlinear Waves in a Generalized Zakharov-Kuznetsov Equation
Advances in Mathematical Physics, 2013 We study the bifurcation phenomena of nonlinear waves described by a generalized Zakharov-Kuznetsov equation ut+au2+bu4ux+γuxxx+δuxyy=0. We reveal four kinds of interesting bifurcation phenomena.

Numerical simulation of capillary gravity waves excited by an obstacle in shallow water; pp. 278–284 [PDF]
Proceedings of the Estonian Academy of Sciences, 2015 Capillary gravity waves excited by an obstacle are investigated by numerical simulations. Under the resonant condition for which large-amplitude solitary waves are generated, solutions of the Euler equations show that the capillary effects induce the ...

On the generation of solitary waves observed by Cluster in the near-Earth magnetosheath [PDF]
Nonlinear Processes in Geophysics, 2005 Through case studies involving Cluster waveform observations, solitary waves in the form of bipolar and tripolar pulses have recently been found to be quite abundant in the near-Earth dayside magnetosheath.
