Internal wave instability: Wave-wave versus wave-induced mean flow interactions
In continuously stratified fluid, vertically propagating internal gravity waves of moderately large amplitude can become unstable and possibly break due to a variety of mechanisms including with some overlap modulational instability, parametric subharmonic instability PSI , self-acceleration, overturning, and convective instability. In PSI, energy from primary waves is transferred, for example,...
متن کاملAn Introduction to the Generalized Lagrangian-mean Description of Wave, Mean-flow Interaction'
The generalized Lagrangian-mean description is motivated a n d illustrated by means of some simple examples of interactions between waves and mean flows, confining attention for the most part to waves of infinitesimal amplitude. The direct manner in which the theoretical description leads to the wave-action concept and related results, and also to the various 'noninteraction' theorems, more acc...
متن کاملFinite-Amplitude Lagrangian-Mean Wave Activity Diagnostics Applied to the Baroclinic Eddy Life Cycle
Lagrangian-mean wave activity diagnostics are applied to the nonlinear baroclinic eddy life cycle in a simple general circulation model of the atmosphere. The growth of these instabilities through baroclinic conversion of potential temperature gradients and their subsequent barotropic decay can exhibit two distinct life cycles. One life cycle results in equatorward propagation of the growing ed...
متن کاملMean Curvature Flow and Lagrangian Embeddings
In this note we provide examples of compact embedded lagrangians in Cn for any n ≥ 2 that under mean curvature flow develop singularities in finite time. When n is odd the lagrangians can be taken to be orientable. By gluing these lagrangians onto a special lagrangian embedding L we provide examples of compact embedded lagrangians in a Calabi-Yau manifold that under mean curvature flow develop ...
متن کاملTranslating Solutions to Lagrangian Mean Curvature Flow
We prove some non-existence theorems for translating solutions to Lagrangian mean curvature flow. More precisely, we show that translating solutions with an L bound on the mean curvature are planes and that almost-calibrated translating solutions which are static are also planes. Recent work of D. Joyce, Y.-I. Lee, and M.-P. Tsui, shows that these conditions are optimal.
