We present in this paper an analysis of bursts of fast pulses in current waveforms associated with positive lightning flashes of type 1 recorded on the Säntis Tower in Switzerland. Type-1 flashes are characterized by the presence of a large unipolar current pulse with characteristics similar to those reported by Berger and co-workers. Several milliseconds to several tens of milliseconds prior to the...
The deployed instrumentation at the Säntis Tower in Switzerland to measure lightning currents and lightning current derivatives is presented. During the first 18 months of operation, the measurement system successfully recorded more than 200 flashes to the tower. 15% of the recorded flashes (namely 30) were of positive polarity, and 1.5% (3 flashes) were bipolar. We also present a summary of the statistical...
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%)...
In this paper, direct lightning current measurements obtained on the Säntis Tower from June 1st, 2010 to May 31st, 2011 are used to evaluate the ability of the EUCLID lightning detection network to detect this type of lightning triggered by a tall tower in terms of detection efficiency, location accuracy and peak current estimates. The Säntis Tower is a 124-meter tall tower sitting on the top of the...
