  We present results of elaborate four-dimensional simulations of the
propagation of ultra-high-energy cosmic rays (UHECR), which are based on a
realistic astrophysical scenario. The distribution of the arrival directions of
the UHECR is found to have a pronounced dipolar anisotropy and rather weak
higher-order contributions to the angular power spectrum. This finding agrees
well with the recent observation of a dipolar anisotropy for UHECR with arrival
energies above 8 EeV by the Pierre Auger Observatory and constitutes an
important prediction for other energy ranges and higher-order angular
contributions for which sufficient experimental data are not yet available.
Since our astrophysical scenario enables simulations that are completely
consistent with the available data, this scenario will be a very useful basis
for related future studies.
