Spontaneous Imbalance and Hybrid Vortex – Gravity Structures

  title={Spontaneous Imbalance and Hybrid Vortex – Gravity Structures},
  author={Michael E. Mcintyre},
After reviewing the background, this article discusses the recently discovered examples of hybrid propagating structures consisting of vortex dipoles and comoving gravity waves undergoing wave capture. It is shown how these examples fall outside the scope of the Lighthill theory of spontaneous imbalance and, concomitantly, outside the scope of shallow-water dynamics. Besides the fact that going from shallow-water to continuous stratification allows disparate vertical scales—small for inertia… CONTINUE READING
