A detailed analysis has been carried out to study the onset times of cosmic-ray decreases occurring during 1978-1982 with respect to the arrival times of interplanetary shocks and magnetic clouds. The observations demonstrate that shocks, magnetic clouds and a combination of both could effectively trigger a cosmic-ray decrease when they are associated with turbulent sheaths of maximum thickness not greater than 15.0 hr (not greater than 0.15 AU). Further, the shocks associated with enhanced solar wind velocity produce a fast decrease and the magnetic clouds accompanied by extended and enhanced magnetic field produce a slow decrease. The decrease, noncorrelated with the arrival times of shocks and magnetic clouds, represents a corotating cosmic-ray decrease produced by corotating streams.
