冬夏典型地磁-电离层暴期间太平洋区域F层行为

本文在前人已公布的暴时电离层动态资料的基础上, 进行了太平洋地区冬至与夏至期间电子总量和F层特征的分析研究, 取得了新的结果.认为在磁暴主相出现之时, 以电子总量为表征的电离层暴达到最明显的程度.以F层为代表的电离层的行为强烈地受控于经度(暴时)、纬度、地磁格局和季节(南北半球)的缔合关系;并且电子总浓度的消长关系需从电离增长率(磁壳层收缩)-电离消矢率(损失系数加大)-电离迁移率(磁共轭迁移和电离峰谷异动)作统一考虑.文中提出了较合理的电离层暴区划意见并讨论了暴情倒相问题. 

The F-region Behaviour over the Pacific Area During the Typical Solstitial Geomagneto-ionospheric Storms

In this paper, features of the total electron content and F-region of the ionosphere over the Pacific area during the typical storms are analysed on the basis of published data and some new results are presented. It is suggested that the ionospheric storm characterized by TECreaches quite distinct degree while the main phase of magnetic storm appears. The behaviour of the ionosphere, mainly the F-region, is dominated strongly by the complex relation of longitude (storm commencement), latitude, geomagnetic configuration and season (the Southern or Northern Hemisphere). It is necessary to consider the growth and decline of TECaccording to the ionization increase rate (magnetic field line retrenchment), depletion rate (loss coefficient rise) as well as transportation rate (ionization transfer between geomagnetic conpugate points and the crest-trough movement). Amore reasonable suggestion with regard to the ionospheric storm division and the phase reverse is proposed.
