| 摘 要： | 本文探讨磁层一电离层耦合过程内中纬地磁指数的变化特点,并与极光电集流和赤道电集流(指数)变化相比较。相关分析和时序叠加分析均表明,高、中、低纬地磁指数变化可归结为磁层一电离层电动耦合的统一物理图象。有R事件的磁暴主相初期和无R事件的磁扰期内,赤道电集流和中纬地磁指数的变化各不相同。这再次证明,耦合分析中将磁层源扰动的直接穿透作用与经电离层内动力过程的效应二者加以区分和综合研究是很重要的。

| Abstract: | Features of the mid-latitude geomagnetic index ASY-Hduring periods of the magnetosphere-ionosphere coupling are analysed. They are compared with feature of the auroral electrojet(AE) index and that of the equatorial electrojet.Both the results of the courrelation analysis and the superposed epoch analysis can be brought into a self consistent physical picture.It is also shown that the diurnal variation of the equatorial electrojet during the main phase of a geomagnetic storm with Revent is different from that on disturbed days when no energy injects into the ring current.All these results prove that it is'important to distinguishs.the effect of magnetospheric disturbance penetrating directly to mid- and lowffetitude from that generated in the ionosphere by dynamic processes. |
