| Resumo | High-speed video records of two bipolar cloud-to-ground flashes were analyzed in detail. They were both initiated by single positive return strokes and were followed by more than one subsequent negative stroke. Due to the elevated cloud-base height of its parent thunderstorm, the initiation processes of each subsequent stroke could be registered optically below cloud base. In the first event (Case 1) it was possible to observe that all four subsequent negative strokes were initiated by recoil leaders that retraced one horizontal channel segment previously ionized by the positive leader that preceded the first stroke. Those recoil leaders connected to the original vertical channel segment and propagated towards ground, producing four subsequent strokes that had the same ground contact point of the original positive discharge. The second event (Case 2), on the other hand, presented fifteen subsequent strokes that were initiated by recoil leaders that did not reach the original channel of the positive stroke. They diverged vertically towards ground, making contact approximately 11 kilometers away from the original positive strike point. These are the first optical evidences that both single- and multiple-channel bipolar flashes occur as a consequence of recoil leader activity in the branches of the initial positive return stroke. For both events their total channel length increased progressively with time at a growth rate equivalent to a propagation speed of the order of 104 m/s, comparable to those reported for typical positive leaders. |
