The intermittent transport due to coherent structures (streamers) is shown to be dramatically reduced by the shearing of mean flow in passive scalar field model, with the scaling ∝ Ω-3. Here, Ω is the shearing rate of the mean flow. This reduction is much stronger than that in turbulent transport (∝ Ω-1) [Kim and Diamond, Phys. Rev. Lett. 91, 075001 (2003)] in the same model. Implications for the transition from low to high confinement (L-H transition) are discussed.
