本文使用柿岗(1924—1981年)女满别和鹿屋(1958—1981年)的磁暴资料,对磁暴的各种特性,进行了统计分析。为进一步验证这些结果,又用IAGA1968—1981年的SSC资料进行了对比分析,其主要研究成果如下: 1)柿岗SSC的发生频次的日变化,早晨5—7点最小,9点开始急剧增加,并且在白天18点以前多,夜间至清晨少。与IAGA资料中同期的日变化相比,两者的变化基本相似。 2)柿岗SC的幅度△H(nT)的日变化,夜间大,上午8—10点最小。而且在女满别最大的幅度比柿岗和鹿屋的都大,最小的幅度比柿岗和鹿屋的又都小。也就是说,越往北,日变化小,幅度越大。因此,可看作是由在高纬度地区的两个急始涡旋电流带来的影响。
In this paper, the data of the magnetic storm in Kedongang (1924-1981) and the deer house (1958-1981) were used to analyze the various characteristics of the magnetic storm. In order to further verify these results, we made a comparative analysis with IAGA1968-1981 SSC data. The main results are as follows: 1) The diurnal changes of the frequency of SSC in persimmon were the lowest at 5-7 points in the morning and the sharp increase at 9:00 , And more before 18:00 in the daytime, night to early morning less. Compared with the same period of diurnal changes in IAGA data, the changes of both are similar. 2) Persimmon Kong SC amplitude △ H (nT) diurnal changes at night, 8-10 in the morning minimum. And in women’s full-scale than the largest number of persimmon Kong and deer housing are large, the minimum amplitude than the persimmon Kong and deer houses are small. In other words, the more the north, the daily change is small, the greater the magnitude. Therefore, it can be considered as the impact of two rapid onset eddy currents in the high latitudes.
