  Weyl anomaly leads to novel anomalous currents in a spacetime with
boundaries. Recently it is found that the anomalous current can be
significantly enhanced by the high temperature for free theories, which could
make the experimental measurement easier. In this paper, we investigate
holographic anomalous currents at a finite temperature. It is found that the
holographic current is still enhanced by the high temperature in dimensions
higher than three. However, the temperature dependence is quite different from
that of free theories. This may be due to the fact that the holographic CFT is
strongly coupled and there is non-zero resistance in the holographic model.
Remarkably, the temperature dependence of holographic anomalous currents is
universal in the high temperature limit, which is independent of the choices of
background magnetic fields.
