Description

Theory of non-local transport has been developed, taking an example of zonal flows (ZFs), the radial correlation length of which is longer than those for microscopic fluctuations. ZF, which is driven by fluctuations at one radius, can suppress fluctuations at distant radii. This mechanism induces new non-local interactions in turbulent transport. That is, strong fluctuations at particular radius can suppress fluctuations at different radius, via induction of ZFs. Stronger fluctuations suppress weaker fluctuations. This is called the seesaw mechanism via ZFs. (author)
