title = "Instability of co-rotating vertical vortices in a stratified fluid",
abstract = "We show numerically, theoretically and experimentally that two co-rotating vertical vortices in a stably stratified fluid are subjected to a new three-dimensional similar to the zigzag instability observed on counter-rotating vortices (Billant \& Chomaz, 2000). This zigzag instability induces the formation of thin horizontal layers with a thickness inversely proportional to the Brunt-V{\"a}is{\"a}l{\"a} frequency. This three-dimensional instability is believed to make stratified turbulence depart from two-dimensional turbulence since it alters the merging of vortices.",
