Notas | Informações Adicionais: Schonland et al. (Progressive lightning, 6, Proc. Roy. Soc. (London), A168, 455-469, 1938), in their seminal streak camera studies of lightning, have identified four events of a peculiar type of negative stepped leader that they termed β 2 , a rather rare variant of the type β leader and in it the second and slower stage of the leader is associated with the appearance of one or more fast dart streamers, which travel rapidly down from the cloud along the previously formed track and cease when they have caught up with the slower leader-tip . During two different campaigns between 2007 and 2011 in Tucson, Arizona, USA, and in São José dos Campos, São Paulo, Brazil, we recorded seven downward leaders that fit in the type β 2 description given by Schonland et al. (1938). All cases occurred between about 5 and 32 km from a high-speed camera that was operating at 4000 frames per second and three of them could also have their electric field changes measured. All the dart streamers that we observed had speeds between 106 and 107 m s-1, in agreement with previous observations of recoil leaders (RLs). Also, during the development of the three cases whose electric field change data was available it was possible to identify a sequence of microsecond-scale pulses preceding the development of the Considering the similarities in the optical and electric field signatures of both phenomena, we propose that the type β 2 negative leaders are the visible manifestation of the development of RLs that were initiated inside the cloud and propagate below the cloud-base during the development of a bipolar, bidirectional leader that precedes a lightning flash to ground. The RLs are initiated in and propagate through channels that were previously ionized by the in-cloud positive portion of a bidirectional leader, eventually connecting to one of its active branches. When they do an intense return pulse of luminosity that optically appears as the dart streamer reported by. |
