Transfer Functions of Short-Period Geomagnetic Variations (0.3min. to 9.0min.) at Kakioka
Sano, Y.
Abstract
In this paper transfer functions of very short-period geomagnetic variations (0.3 min. to 9.0 min.) at Kakioka during the period from Jan. 1977 to Mar. 1979 have been analyzed. A real-time calculation method of such the transfer functions by the KASMMER system and some interesting results are described.
From the present analysis, it is found out that there is an interesting long term variation like a seasonal or annual variation in time change of Au and Bu transfer functions, particularly in the shorter-period components. While, in the present transfer functions not only a great random error component but also a great systematic one depending upon the former or the geomagnetic activity are recognizable.
