AbstractWe present a statistical study of decimetric type III radio bursts, coronal mass ejections (CMEs), and H alpha flares observed in the period from July 2000 to March 2005. In total, we investigated 395 decimetric type HI radio burst events, 21% of which showed apparent correlation to CMEs that were associated with Ha flares. We noticed that the Ha flares which were strongly associated with CMEs were gradual events, and 82% of them took place before CMEs appeared in the field of view of LASCO C2; that most of the CME-associated radio bursts started in the frequency range around 750 MHz with a frequency drifting rate of several hundred MHz s(-1), of which both positive and negative ones were recognized; and that the correlation of type III radio bursts to CMEs without associated flares is fairly vague, less than 9%.
