| Keywords | The present work shows high-speed videos of two upward flashes that started with positive upward leaders and instead of being followed by negative subsequent return strokes they were followed by positive subsequent return strokes. In both cases after the positive leaders developed recoil leaders (RL) appeared in their decayed branches as would be usual in negative upward lightning flashes. However in these flashes the negative end of a recoil leader connected to a positive leader of an intracloud (IC) flash nearby. The connection initiated a downward positive leader that re-ionized the decayed channel of the upward flash all the way to the tower giving origin to a positive subsequent return stroke. This work shows that RL do play an important role in the occurrence of bipolar upward flashes and their interaction with IC flashes can provide explanations for all types of bipolar upward flashes initiated by upward positive leaders.Plain Language SummaryThe increasing number of tall buildings and towers and the rapid expansion of wind power generation has also increased the concerns about damages caused by upward flashes. Although upward flashes are not the most common type of flashes in nature they can pose a serious threat to tall structures. They are usually initiated by a positive upward leader that starts at the tip of the structure. After reaching cloud base the discharge ends or is followed by a negative downward leader that strikes the tower and produces an intense negative discharge known as a return stroke. This common type of upward flash is named negative upward flash. The present work presents high-speed videos of a rare type of upward flash the bipolar upward flash. In this flash after the propagation of the positive upward leader another positive leader retraces the same path traveled by the original upward leader but in a downward manner resulting in a positive return stroke. The increased threat of damage caused by this rare flash is due to the intense positive return stroke and long duration current that frequently follows. This work explains how this and other types of bipolar flashes are possible |
