Temporal variation data on cosmic ray intensity in the stratosphere and at sea level for the periods 1957-1958 and 1969-1971, periods of polarity reversal of the overall solar magnetic field, are analyzed. It is found that the 11-year modulation of galactic cosmic rays is not simply the summation of the effect of solar wind from active regions and with the effect of the dipole field of the sun. For modulation, an interaction of the plasma flux from active regions with the dipole field is necessary. This interaction is manifested, for example, in shock waves which form during the motion of hot plasma through the heliomagnetosphere. In this case the dependence of cosmic ray intensity on heliographic latitude of sunspots can be conditioned by the dependence of shock wave initiation on the angle between the direction of plasma motion and the force lines of the dipole field.
