  The steering effect on the growth of islands is investigated by combining
molecular dynamics (MD) and kinetic Monte Carlo (KMC) simulations. Dynamics of
depositing atoms and kinetics of atoms on a substrate are realized by MD and
KMC, respectively. The reported experimental results on the asymmetric island
growth [van Dijken {\it et al.}, Phys. Rev. Lett. {\bf 82}, 4038 (1999).] is
well reproduced. A salient phenomenon, the reversal of the asymmetry, is found
as the island size increases, and attributed to the asymmetric flux on the
lower terrace of island.
