An Analysis of the Distribution of Inter-Flash Time Intervals in the Area of the Säntis Tower

In this paper we analyzed the time intervals between flashes in the Säntis area for three highly active storms and also for a period of 21 months. The overall distributions of inter-flash time interval are found to be very similar and reasonably represented by an exponential probability distribution function. The mean value of the inter-flash interval for the 21-month long period is 23 seconds. About half of the flashes occurred within 5 seconds of the previous flash.
