地球磁层中的电场是研究磁层物理的重要参数,目前常用的对流电场有均匀晨昏电场和投影电场.电离层电场可以看做磁层电场沿磁力线在电离层的投影,本文选取的电离层电场模型为Weimer(2001模式)电场.利用T96磁场模式,沿磁力线将电离层电场投影到磁层空间,得到一个新的磁层电场模式,并讨论了磁暴、行星际磁场(IMF)、太阳风参数和亚暴等对磁层电场的影响.利用该模型计算的电场结果与卫患探测结果相符. |

Global electric field within magnetosphere is an important parameter to research magnetospheric physics. At present, average dawn-dust electric field and projected electric field as convection electric field within magnetosphere are applied usually in space physics. In this paper, we adopted Weimer's electric field as the mode of ionospheric electric field. Then, we projected the ionospheric electric field to magnetospheric space along lines of magnetic force of T96, and got a new model of magnetospheric electric field. We also discussed the impact of magnetic storm, IMF,solar wind parameters, and substorm on magnetospheric electric field. The computing result of this model was consistent with the results delected by satellites. |
