| Abstract | 为了研究地磁活动指数D_(st)受太阳风参数影响,包括行星际磁场(IMF)南向分量B_(st)、太阳风速度V_(?)和太阳风-磁层发电机电动势U调制的机制,应用太阳风-磁层-电离层输入-输出[I(t)-O(t)]电网络模型,对磁层亚暴与磁层暴过程中,B_z(t)-D_(st)、V-a(t)-D_(st)和U(t)—D_(st)的激励-响应特性进行模拟。研究表明,B_z是形成亚暴与磁层暴的前提条件,V_(st)是形成亚暴与磁层暴的充分条件,二者统一于电动势U_(st)研究结果与观测结果一致。 |
| Other Abstract | In order to study the modulating mechanism of the Dst index versus solar wind parameters, including the intherplanetary magnetic field (IMF), Bz, the solas wind speed, Vs, and the electromotive fore (EMF), U, we simulate the input-output characteristics of Bz-Dst,Vs-Dst,U-Dst with the input-output network model of the system of solar wind-magnetosphere-ionosphere. The model predicts that Bz is the preroquisite for substorms and storm, and Vs, is the additional condition for them. Bz and Vs, are integrated to EMF，C' (t).The results are well-accordant with the observed results. |
