| 英文摘要 | Using 141 cme-interplanetary shock (cme-ips) events and fof2 from eight ionosonde stations from january 2000 to september 2005, from the statistical results we find that there is a "same side - opposite side effect" in ionospheric negative storms, i.e., a large portion of ionospheric negative disturbances are induced by the same-side events (referring to the cmes whose source located on the same side of the heliospheric current sheet (hcs) as the earth), while only a small portion is associated with the opposite-side events (the cmes source located on the opposite side of the hcs as the earth); the ratio is 128 vs. 46, and it reaches 41 vs. 14 for the intense ionospheric negative storms. in addition, the ionospheric negative storms associated with the same-side events are often more intense. a comparison of the same-side event (4 april 2000) and the opposite-side event (2 april 2001) shows that the intensity of the ionospheric negative storm caused by the same-side event is higher than that by the opposite-side event, although their initial conditions are quite similar. our preliminary results show that the hcs has an "impeding" effect to cmeips, which results in a shortage of energy injection in the auroral zone and restraining the development of ionospheric negative perturbations. |
