| 摘 要： | 一、引言地磁場扰动的原因,至今仍是地球物理学者与天体物理学者所共同关切的問題.有許多理由說明太阳是使地磁产生扰动的主要根源.一般說来,在任何时期內,太阳活动愈強,地磁活动也愈強.然而,即使是在太阳活动最弱的年份,地磁場也可能产生不小的扰动.既然在太阳活动低年,作为太阳活动标誌的黑子数很少,那么,使地磁产生扰动的根源又是什么呢?对于这个問題,20多年以前提出了所謂M区来做答案.

| Abstract: | The author has studied the statistical relation between the coronal green line and geomagnetic activity. The data of Climax coronal line 5303 geomagnetic Kp index are analysed for the years 1950-1953. Three strong and weak regions are selected for each month, and these regions are divided into three groups according to their heliographic latitudinal distance from the center of solar disk:0°-10°, 10°-20°, 20°-30°. For each group the effect of the central meridian passage has been analysed by superposed-epoch method. The principal results are summarized as following: 1. The strong or weak coronal regions have different geomagnetic effects. On third day after the central meridian passage of strong regions, the geomagnelic activity becomes a minimum; but on third day after the central meridian passage of weak regions, the geomagnetic activity becomes a maximum. 2. The effect of either the strong or the weak coronal regions on the geomagnetic field is more evident for the 0°-10° group than that for the 20°-30° group. This fact confirms the radial property of solar corpuscular radiation. |
