Solar cycle effect on geomagnetic storms caused by interplanetary magnetic clouds

Author(s) : Wu, C.-C. , Lepping, R. P.
Description : We investigated geomagnetic activity which was induced by interplanetary magnetic clouds during the past four solar cycles, 1965?1998. We have found that the intensity of such geomagnetic storms is more severe in solar maximum than in solar minimum. In addition, we affirm that the average solar wind...
