Measurement of Electric Charge in Thundercloud by Means of Radiosonde

[摘要] A radiosonde for measuring the electric charge on precipitation elements was designed and individual electric charge in cloud was observed. Three specially designed radiosonde transmitters were used for observation of a thundercloud and cumuli. The general feature of electric charge distribution with height in thundercloud was nearly the same as that given by Simpson and Scrase. The amount of individual electric charge on precipitation particles in thundercloud was determined. A layer of positive electric charge of 1km in thickness at an altitude of 12km is supposed to spread widely in the thunderstorm season.
