Abstract [en]
Data from the lightning detection system owned by SMHI mainly from 2015-2020 was used to model the peak current. The log-normal distribution and the generalised extreme value distribution were tried and the later was slightly better. The median of the peak current was found to be lower than the value recommended by Cigre, in particular for the first stroke in a flash. In part, this can be due that the lightning detection system is calibrated for the subsequent negative strokes. The duration and the interval of the strokes were as expected. No correlation between current and rise time was found, whereas there were some differences between the regions in Sweden.
