Query: Formation of edge pressure pedestal and reversed magnetic shear due to
  toroidal rotation in a tokamak equilibrium   Toroidal rotation is well known to play significant roles in the edge
transport and L-H transition dynamics of tokamaks. Our recent calculation finds
that a sufficiently strong localized toroidal rotation can directly bring out
the formation of edge pressure pedestal with reversed magnetic shear that is
reminiscent of an H-mode plasma, purely through the effects of toroidal
rotation on the tokamak MHD equilibrium itself. In particular, the enhanced
edge toroidal rotation enables a substantial peaking of the parallel current
profile near edge in higher $\beta$ regimes, which leads to the flattening or
reversal of the local $q$ (safety factor) profile. Here the formation of
pressure pedestal along with the reversed magnetic shear region is shown to be
the natural outcome of the MHD tokamak equilibrium in a self-consistent
response to the presence of a localized toroidal rotation typically observed in
H-mode or QH-mode.
