ホイッスラーの分散の二三の特性
SOME CHARACTERISTICS OF THE DISPERSION OF WHISTLERS

open access
The author studied some characteristics of dispersion (D) of whistlers for 4 years since the beginning of IGY, and found that in diurnal variation D decreases in general from sunset to sunrise and increases thereafter. This tendency is observed very clearly in winter but not in summer, and it becomes umbiguous in accordance with the decrease of solar activity. At Toyokawa D is minimum in winter and maximum in summer, while at Wakkanai it is minimum in winter and summer and maximum in spring and autumn, contradictory to Helliwell's report, suggesting geomagnetic latitude dependence. As to solar activity, D correlates with sunspot number with time lag of 1 to 2 months. Investigating D individually, the author also found that in storm days the diurnal variation of D is exaggerated.
