Some Statistical Properties of ssc Storm at Kakioka
Yamaguchi, Y.
Abstract
The frequency distributions of such quantities as usually reported in tables of magnetic storm are examined, based on the recent data at Kakioka. The frequency distribution of the rise time of ssc's may be different from that obtained from the old data.
The relations among the amplitude, the rise time, the maximal K, the range etc. at Memambetsu, Kakioka and Kanoya are examined. The main results are as follows. 1) The larger the amplitude of ssc's the larger the maximal K and/or the range of storms. 2) Any relation between the amplitude of ssc's and the duration of the initial phase is obscure. 3) The relation between the amplitude and the rise time of ssc's in middle latitude is different from those in low latitudes and in high latitudes. 4) The relation between the range and the maximal K can be represented by the formula y = aebx.
