The contribution of coherent structures to the statistics of turbulent flow comprises a central problem in turbulence physics. Adopting a vorticity representation of fluid flow, one can define coherent structures to be vorticity patterns characterized by a number of parameters. In order for such patterns to persist in time their interactions should only cause their transition from one characteristic parameter range to another without simultaneous change of their mathematical definition. This paper presents a novel turbulence model developed in order to address a kind of low dimensional coherent structure capable of representing the dynamically important vorticity field as a collection of its manifestations.
