DESCRIPTION:Dr. Jose-Miguel Reynolds Barredo\, Department of Physics UAF/
  Carlos III de Madrid\, Spain\nInteresting dynamics are found in the phase
  of Fourier modes in 2D turbulence simulations. The equations investigated
  can represent either 2D plasma drift wave turbulence or quasi-geostrophic
  turbulence. The interesting dynamics are found to be caused by the appear
 ance of strong coupling in the phase of the Fourier modes. This happens in
  regions inside the high-k region of the spectrum where dissipation is dom
 inant. In addition\, a strong burst of energy transfer is associated with 
 the phase-coupling event. Finally\, these intermittent events can be shown
  to have strong connections with the saddle points of the velocity field. 
 The mechanisms\, importance and possible uses of these coherent events wil
 l be discussed.
