塔筒触发雷电的电流参数对于风力涡轮机等高处物体的防雷至关重要。向上闪电的启动条件仍然是正在进行的研究的主题，可能需要考虑当地的条件。本文总结了奥地利盖斯伯格塔（GBT）向上闪电的测量结果，并与塔或火箭触发闪电的其他一些测量结果进行了比较。由正向上先导引发的向上闪电是在 GBT 观察到的最常见的闪电类型 (93%)，尽管如此，3% 的放电是双极的，4% 的塔闪将正电荷降低到地面。正闪光由带负电的先导启动，并观察到与步进先导过程相关的短电流脉冲。
Current parameters of tower triggered lightning are of interest for the lightning protection of high objects, such as wind turbines. Initiation conditions of upward lightning are still subject of ongoing research and probably needs consideration of local conditions. In this paper results of measurements of upward lightning from the Gaisberg Tower (GBT) in Austria are summarized and compared with some other measurements on towers or rocket-triggered lightning. Upward lightning initiated by a positive upward leader is the most common type (93%) of lightning observed at the GBT, nevertheless 3% of the discharges are bipolar and 4% of the tower flashes are lowering positive charge to ground. Positive flashes are initiated by a negatively charged leader and short current pulses associated with the stepping leader process are observed.
