Abstract

The recent progress on the coronal mass ejections (CMEs), including observational results obtained by Yohkoh, SOHO, WIND, Ulysses, Geotail and polar, are presented. The relations between CMEs and solar activities, interplanetary disturbances as well as geospace environmental variations are investigated. Some typical theoretical models and numericals imulation results on the formation mechanism and propagating process of CMEs are described. Finally, some noticeable problems for future research are posed.
