It is generally known that high-speed CMEs are associated with flares, and that flares with longer durations have higher correlations with CMEs. However, we also know that short-duration flares can also be associated with CMEs (Kahler, Sheeley and Liggett 1989, and Harrison 1995). By studying the properties of major flares as observed by Yohkoh, and their associated CME data from SOHO/LASCO, we discuss similarities and differences of flare-associated CMEs and those that come from quiescent regions, and study how the flare properties are inherited in the associated CMEs. We also emphasize the 3-d nature of CMEs when we interpret their speeds in the plane of the sky, by including those events that originate from disk regions. For disk events, the magnetic properties around the initiation regions are studied. We hope that this study further clarifies the relationship between flares and CMEs.
