Current Parameters of Lightning Discharges Measured at the Peissenberg Telecommunication Tower

In 1992 new lightning measurements were started at the Peissenberg telecommunication tower. The tower is situated in the south of Germany nearby Munich. All strikes to the tower were upward initiated ground-to-cloud flashes except of one event identified as negative downward initiated cloud-to-ground flash. The majority of the ground-to-cloud flashes were of negative polarity lowering negative charge to ground.

Based on more than 100 negative ground-to-cloud flashes updated statistics of current parameters are given distinguishing between different current components, such as impulse and continuing currents. The statistics include the current peak values, the maximum current derivatives and the full widths on half value of the current derivatives. Further, the meteorological condition and the striking probability are examined.
