This paper presents statistical distributions of lightning current parameters based on the lightning current and current-derivative waveforms measured at the Säntis Tower site in 2010 and 2011. The total number of flashes analyzed in this study was 167, which includes nearly 2000 pulses. The statistical distributions refer to upward negative flashes. It is shown that negative flashes are mainly concentrated...
We present statistical data on the risetime of lightning current pulses in negative upward flashes measured on the Säntis tower in 2010 and 2011. Two different definitions were used to determine the current risetime. The first is the t10–90 rise time usually adopted in lightning applications and lightning standards. The second one is the risetime associated with the maximum rate of rise tmr given...
We present in this paper measured current waveforms associated with positive flashes recorded on the Säntis tower, Switzerland, in Summer 2010. About 20% of the recorded flashes were of positive polarity (transported positive charge to ground), all of them being recorded in July and August. This percentage is considerably larger than the values observed in other studies in summer months (3% to 6.5%)...
