Abstract
The importance of the E x B Bow shear in various enhanced confinement regimes is discussed in terms of the turbulence suppression criterion in general toroidal geometry. This criterion is then further generaliz ed to include the poloidal angle dependence of the equilibrium electro static potential. The implication of the recently observed in-out asym metry in the fluctuation behaviour in DIII-D VH-mode is discussed.
