摘要:

A theory is presented which describes the along-front propagation and cross-front trapping, due to the absorption by multiple critical-layers, of ageostrophic non-divergent perturbations of baroclinic jets. The perturbations are dispersive neutral vorticity waves which use the jet vorticity gradient as a pseudo-β effect.
