Periodic oscillations of atmospheric electric field during snowfall in the Tokyo metropolitan area

Abstract We report the first observations of periodic oscillations of an atmospheric electric field simultaneously derived by field mills at four observation sites at a distance of 50–65 km in metropolitan Tokyo. Oscillations were detected during a snowfall event on 23–24 November, 2016. The main pe...
