本文给出地磁静日变化场垂直和水平分量的幅度、相位及产生Sq的上空电流体系的视焦点纬度的逐日变化现象的初步统计结果,为进一步研究这一逐日变异性提供基本事实根据。
The preliminary statistical results of the daily change of the vertical and horizontal components of the geomagnetic stationary diurnal variation field and the apparent focal point latitude of the over-current system generating Sq are provided in this paper, which provide the basic factual basis for further studying this daily variability.
