摘要
简要介绍了地磁台链观测在极光带电集流、赤道电集流、中低纬度大尺度电流体系、太阳风-磁层-电离层-高层大气能量耦合、高-中-低纬的扰动传输、磁层中磁流体波的传播、主磁常荚期变化等研究中的应用,综述了地磁台链观测在地磁与空间物理研究中的物理基础和研究现状,着重回顾了IMS 期间6个高纬子午台链的观测研究,总结了中国地磁台链研究的初步结果.中国所处的独特地理位置和广阔的经纬度展布提供了建立全球唯一的闭合子午圈台链的可能性.中国台链向北与俄罗斯东西伯利亚地磁台相连,一直延伸到北极光带,向南与菲律宾、印尼、澳大利亚台站相连直达南极区中山站,通过南极与对面子午线上的长城站相连,并与南美、北美台站构成一条闭合的子午圈台链.可以预料,这条台链的观测资料将为地磁与高空物理研究提供宝贵的资料,对研究日地整体行为将会有重要意义.
A brief introduction is made for applications of geomagnetic station chain data in studies of theauroral electrojet,the equatorial clectrojet,large-scale current systems at mid-low latitudes,energy coup-ling of the solar-wind-magnetosphere-ionosphere-upper atmosphere,disturbance trasfer between highand low latitudes,MHD wave propagation in the magnetosphere,secular variation of the magnetic mainfield and others.Physical background and recent developments of geomagnetic station chain observationsand studies are summarised.An emphasis is put on IMS meridian chains and China meridian chain.Theunique geographic location of China makes it possible to construct a closed meridian chain ofmagnetometers.which will play important role in geomagnetism and space physics.
