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...
Patch behaviour and predictability properties of modelled finite-amplitude sand ridges on the inner shelf
Patch behaviour predictability properties modelled finite-amplitude sand ridges inner shelf
2009/11/2
The long-term evolution of shoreface-connected sand ridges is investigated with a nonlinear spectral model which governs the dynamics of waves, currents, sediment transport and the bed level on the in...
Baroclinic Instability over a Slope. Part II：Finite-Amplitude Theory
Baroclinic Instability Finite-Amplitude Theory
2009/3/24
Baroclinic instability of a circular current is modified by the presence of a unidirectional bottom slope. An analytical theory is developed for the slightly unstable flow regime over a weak slope. Th...
Symmetric Finite-Amplitude Rotational Water Waves

2009/3/7
Two forms of a tw0-dimensional streamfunction solution for symmetric periodic water waves on a fluid with a vertical distribution of vorticity are presented. The magnitude of the vorticity varies line...
Finite-Amplitude Baroclinic Disturbances in Downstream Varying Currents
Finite-Amplitude Baroclinic Disturbances Downstream Varying Currents
2009/3/7
The finite-amplitude dynamics of baroclinic disturbances in currents whose cross-stream structure varies in the downstream direction is investigated.
It is first shown under what circumstances downst...
Double-Diffusive Interleaving. Part II：Finite Amplitude, Steady State Interleaving
Double-Diffusive Interleaving Finite Amplitude Steady State Interleaving
2009/1/16
The exponentially growing solutions of the linear stability analysis of double-diffusive interleaving are allowed to grow to finite amplitude. At this stage the double-diffusive fluxes across the intr...
Finite Amplitude Effects on Deep Planetary Circulation over Topography
Finite Amplitude Effects Topography Deep Planetary Circulation
2009/1/5
Steady flow over large-scale bathymetric changes of a uniform zonal current in a two-layer fluid is studied under the assumptions that it is geostrophic, that relative vorticity can be ignored, that v...
Finite-Amplitude Long Waves on Coastal Currents
Finite-Amplitude Long Waves Coastal Currents
2008/12/27
Two models of coastal currents are described that allow fully nonlinear wavelike solutions for the limit of long waves. The first model is an adaptation of a model used by Yi and Warn for finite-ampli...

Gulf of Maine coastal ocean circulation model Stratified Tidal Rectification Georges Bank
2008/12/12
Tidal rectification over an idealized two-dimensional cross section of Georges Bank, which is a large, shallow, elongated submarine bank in the Gulf of Maine, is studied using a primitive equation coa...

Behavior of Linear Beam-Plasma Instabilities in the Presence of Finite Amplitude Circularly Polarized Waves
Linear Beam-Plasma Instabilities Finite Amplitude Circularly Polarized Waves
2004/12/31
We review the effect of finite amplitude circularly polarized waves on the behavior of linear ion-beam plasma instabilities. It has been shown that left-hand polarized waves can stabilize linear right...
