| 英文摘要 | The characteristics of accelerating coronal mass ejection (cme) and decelerating cme happening during 1997-2003 are analyzed. prediction tests are made for geomagnetic disturbance events caused by the gradually accelerating cme-associated interplanetary shock waves and the decelerating cme-associated interplanetary shock waves, which can be identified by interplanetary scintillation (ips) observation during 1997-2003. new membership functions and new correctional item of onset time of geomagnetic disturbances are respectively constituted for two kinds of cme. the main results are: for the onset time of the geomagnetic disturbance in the accelerating cme, the relative error between the observation, t(obs), and the prediction, t(pre), delta t(pre)/t(obs) <= 10% for 21.86% of all events, <= 30% for 78.13% and >= 50% for only 9.36%; for the decelerating cme, delta t(pre)/t(obs) <= 10% for 25.00% of all events, <= 30% for 84.37% and >= 50% for only 3.13%. these results show that the method has good feasibility for the geomagnetic disturbance predictions. |
