| | By the mechanism of drift motion of polorized electric field the electrons of the solar wind may penetrate into the magnetosphere through the neutral point. These electrons trapped in the geomagnetic field will drift eastward, carrying a westward electrical current. Before these electrons drift a closed cycle around the earth, the distribution of electrons and consequently the current and the magnetic field recorded at the earth surface of the equatorial region will be asymmetrical with respect to local tim... | | 太阳带电粒子流通过磁边界层的中性点或阻塞点,由于极化电場的漂移运动或雷萊-泰勒(Rayleish-Taylor)不稳定运动,穿透磁层而进入地磁場被輻射带所捕获。这些被捕获的电子将向东漂移而形成西向电流。在它們围繞地球一周形成封閉的电流环以前,由于地球的自轉以及这个电流弧对地球各地的相对位置的不同,电流分布以及它在地面磁赤道附近所产生的磁場分布都将是不均匀的,对經度来耕是不对称的。本文假定电子繞地球的漂移周期为两天,計算了当磁暴开始时位于地方时00,06,12及18小时的台站記录的磁場随“暴时”T_(st)变化的曲线。理論結果与用佘山及洪伽幼地磁台站得到的統計結果是一致的。 | | 文摘来源 | | The physical characteristics of whistler ducts in Earth's magnetosphere is inquired theoretically. By using two kinds of model of ducts in which the VLF electromagnetic waves are guided, we obtain the distributions of magnetic field and current in the whistler duets. When the magnetic field deviates from potential or force-free field, the field-aligned current can be produced, and it relates closely with the intensity and lifetime of ducts. On the basis of these results, we may conclude that a stronger fiel... | | 本文在理论上探讨了地球磁层中哨声导管的物理特征。利用两种能够引导甚低频电磁波的导管模式,求得哨声导管中磁场和电流的分布。当磁场偏离势场或无力场时,将会产生场向电流,该电流与导管的强度和稳定维持密切相关。根据这些结果,我们认为高纬磁层中观测到的较强的场向电流,是高纬地区地面台站频繁接收到哨声及其回波的一个重要原因。 | | 文摘来源 | | Studies of the behavior of winter nighttime increases (WNI) in total electron content (TEC) of the ionosphere at three stations, South Uist, Hawick and Aberystwyth, U. K. during a period of low solar activity are presented.
