Comment on the vortices of the early phase of the ELMs

Abstract

We discuss a possible perspective on the process of transition from the layer of sheared poloidal rotation in the H-mode to a set of discrete filaments that concentrate vorticity and current density. They may be precursors of the Edge Localized Modes.
