The dynamic features of the low-intermediate--high-(L-I-H) confinement transitions on HL-2A tokamak are presented. Here we report discovery two types limit cycles (dubbed type-$Y$ and type-$J$), which show opposite temporal ordering between radial electric field turbulence intensity. In type-$Y$, appears first after an L-I transition, grows first, followed by localized field. contrast, leads type-$J$. turbulence-induced zonal flow pressure-gradient-induced drift play essential roles in...

In this paper, recent progress on experimental analysis and theoretical models for non-local transport (non-Fickian fluxes in real space) is reviewed. The non-locality the heat momentum observed plasma, departures from linear flux-gradient proportionality, externally triggered phenomena are described both L-mode improved-mode plasmas. Ongoing evaluation of 'fast front' 'intrinsically non-local' models, their success comparisons with data, discussed
