  Galactic transport models for cosmic rays involve the diffusive motion of
these particles in the interstellar medium. Due to the large-scale structured
galactic magnetic field this diffusion is anisotropic with respect to the local
field direction. We included this transport effect along with continuous loss
processes in a quantitative model of galactic propagation for cosmic ray
protons which is based on stochastic differential equations. We calculated
energy spectra at different positions along the Sun's galactic orbit and
compared them to the isotropic diffusion case. The results show that a larger
amplitude of variation as well as different spectral shapes are obtained in the
introduced anisotropic diffusion scenario and emphasize the need for accurate
galactic magnetic field models.
