On the Calm Day's Variations of the Small-Ion Concentraions at Kakioka and some Relations to the Other Atmospheric-Electric Elements.


Kawamura, M.


Abstract

 Since January of 1951, the continuous simultaneous measurements of potential gradients, space charge densities and small-ion concentrations have been carried out at the Kakioka Magnetic Observatory. But unfortunately, the observational data of small-ions on calm days are very little compared with those of the other elements, because of the difficulties of the keeping of good instrumental conditions. So that, we could not quantitatively treat them. In the present paper, the relations among these atmospheric-electric elements were examined in some detail. At the same time, the diurnal and seasonal variations of both small-ion concentrations and small-ion ratios were described. Making use of this ratio, predominance of the occurrence of negative space charge may be easily explained. Lastly, the writer estimated the combination coefficients from Whipple's theory.
