摘要：

We have developed a method of relativistic particle trajectories to model the cosmic ray intensity dynamics in the presence of solar wind disturbances. The probability of detecting the precursors of disturbances has been found to depend on various conditions. In general, the dynamics of the distribution of precursors at the magnetospheric surface is in agreement with measurements.
