| Resumo | The processes and mechanisms that lead to the formation of new ground contacts (NGCs) in negative multiple ground contact flashes (MGCFs) are investigated through case studies. This was achieved through the analysis of a dataset collected by a network of eight slow electric field antennas, high- and standard-speed video cameras and ten Lightning Mapping Array (LMA) stations installed in Kansas, USA from May to August 2013. Nine natural MGCFs were analyzed in detail and the in-cloud processes that led to their NGC strokes seemed to be intrinsically related to the horizontal distance between the different ground contact points. Widely-spaced NGCs (separated by over one kilometer) were formed from in-cloud branches that were initiated away from the preceding channels to ground, although the LMA plots clearly showed a common root. This is consistent with the existence of multiple closely-spaced regions of high (and lower) negative charge density within a cloud, or with horizontal variations in the lower positive charge region that can facilitate or inhibit preliminary breakdown in specific areas. Closely-spaced NGCs (separated by hundreds of meters), on the other hand, were formed when a subsequent dart leader diverged from the original path of a preceding stroke as it was already moving towards ground, a process that can be also be seen in the video records. In both types of NGC formation, a fast field recovery was observed in close (up to 5 km) electric field measurements following the stroke that preceded the NGC, suggesting that charge with the same polarity as the return stroke was accumulating in the channel and not flowing to ground. For contrast, ten case studies of multi-stroke, single ground contact flashes were analyzed and none of them presented this signature. | |||
