Instability of equivalent-barotropic riders

Instability of equivalent-barotropic riders

It is shown, by the integration of numerical initial-value problems, that modon-with-rider solutions to the equivalent barotropic equation are unstable in the parametric range relevant to Gulf Stream rings. The fastest growing mode is found to have azimuthal wavenumber 2.
