Scientific paper

The effect of the drift of fast charged particles in the IMF on the space-time and energy characteristics of the distribution function of solar cosmic rays (SCRs) is investigated on the basis of a numerical solution of the diffusion and kinetic equations for SCR propagation. It is shown that curvilinear and gradient drifts of high-energy protons produce a large change in the intensity time profiles and a significant softening of the SCR proton energy spectra at energies above 1 GeV. It is suggested that the observed delay in the arrival time of high-energy protons at the earth relative to the flare explosive phase may be due to particle drift in the IMF.
