摘要：

The article reports oil recent developments, in the theory of secondary instability in drift ion temperature gradient turbulence. Specifically, the article explores secondary instability as a mechanism for zonal flow generation, transport barrier dynamics and avalanche formation. These in turn are related to the space time statistics of the drift wave induced flux, the scaling of transport with collisionality and beta, and the spatio-temporal evolution of transport barriers.
