Based on observations of solar activity from LASCO and EIT detectors and GOES satellites on SOHO ships and observations of solar wind plasma and interplanetary magnetic fields by ACE and Wind satellites around Earth’s orbit, the effects of CME, Interplanetary magnetic and geomagnetic storms, including the distribution of the solar-source region of the halo CME with geomagnetic effect, the mid-cycle analysis of CME, the threshold of interplanetary parameters that generate geomagnetic storms, etc. As the interplanetary A kind of complex projectile is proposed for the first time, and the concept of multiple magnetic clouds is proposed for the first time.According to the observed cases, some observed features of multiple magnetic clouds are summarized and considered to be potentially powerful geomagnetic effects.In addition, using the observed data, Shock wave into the magnetic cloud and cause the phenomenon of geomagnetic storm.Through the establishment of a simple theoretical model, the initial analysis of shock wave in the process of crossing the magnetic cloud, can cause changes in the intensity of geomagnetic storm
