Observations of the Atmospheric Electric Field at Syowa Station, Antarctica

[摘要] An observation of the atmospheric electric field strength was carried out by means of a Field Mill type electrometer at Syowa Station (69°00'S, 39°35'E), Antarctica, from the beginning of Feb. 1968 to the end of Jan. 1969. As a result, the following interesting data were obtained: (i) no remarkable diurnal variations in undisturbed electric field, (ii) a positive correlation between the positive electric field and wind velocity, (iii) undisturbed electric field accompanied by southerly winds, (iv) an electric field accompanied by drifting and blowing snow, (v) a difference of the commencement time of the increase of a positive electric field and the increase of wind velocity, (vi) a serrated pattern of positive electric field and (vii) a disturbance of the electric field as influenced by the aurora.
