  We discuss the effect of chiral anomaly as a possible mechanism for
triggering formation of domains of disoriented chiral condensate (DCC) in
relativistic heavy ion collisions. The anomalous $\pi^0 \to 2 \gamma$ coupling
and the strong, Lorentz contracted electromagnetic fields of the heavy ions
combine to produce the ``anomaly kick'' to the field configuration of the
neutral pion field. We implement the effect of anomaly kick in our numerical
simulation of the linear sigma model in a schematic way which preserves its
characteristic features: the effect is coherent over a large region of space
but is opposite in sign above and below the ion scattering plane. We
demonstrate by detailed simulations with longitudinal expansion that the DCC
domain formation is dramatically enhanced by the anomaly kick in spite of its
small absolute magnitude. We examine the behavior of various physical
quantities such as pion fields, the axial vector currents, and their
correlation functions. Our results also provide useful insight into the
mechanism and properties of DCC domain formation, in general. Finally, we
discuss some experimental observables which can signal the anomaly induced
formation of DCC.
