We analyze a specific initial condition, the swirling ring with azimuthal perturbations, from which originate vortex dynamics events leading to a localized but strong vorticity intensification. The aim is to understand the possible development of a finite time singularity, in the context of inviscid flows, and its relevance to the study of intermittency, as one of the most challenging aspects of turbulence.
