 note = {Cloud discharges take place between the upper positive and the lower negative charged regions in a thundercloud. The effective positions of charges are respectively 7-10 and 4 6km. high from the ground, and the mean inclination of the axis connecting the two charges is lower than 30°. The main process of a cloud discharge involves a branched positive streamer that proceeds downward with the velocity of the order of 10^6 cm/s. When the tip of the slow main process arrives at a local close region of the negative charges, a rapid negative streamer with the velocity of lO^8 cm/s. or more ascends the pre ionized channel formed by the slow process. The rapid streamers occur repeatedly more than ten times in a slow process, and each streamer travels about 1 km. and discipates 1 c. on the average. The discharge inside the cloud accompanied to the ground strokes is likewise constructed of an upward slow positive streamer and many downward rapid negative streamers. The rapid streamers based on the larger local charged regions are able to extend toward the ground and form the succeeding dart leaders.},
