The north-south anisotropy of cosmic rays is investigated as a function of the azimuth angles of normals to the fronts of interplanetary shock waves from the time of beginning of Forbush decreases. The time difference between the beginning of a decrease at a northern and southern station is computed on the basis of a simple model of field geometry with the vectors of the normals and of the interplanetary magnetic field lying strictly in the plane of the ecliptic. It is shown that an important part in anisotropy is played by the gradient cosmic-ray flux. 10 references.
