| Resumo | The objective of this work is the analysis of overall characteristics of 35 cloud-to-ground (CG) strokes that presented two or more contact points to the ground in a millisecond scale. This dataset includes both the classical forked strokes (first observed in streak camera records) and the new class of this type of phenomenon, called upward illumination strokes, introduced in more recent works. The genesis of the latter is very similar to the classical forked strokes, i. e., one branch from the main trunk of a stepped leader produces a second stroke after the first return stroke occurs. The main difference from the classical forked stroke events are: a) UI stroke channels appear to completely disconnect from the main trunk during its development, b) the time between strokes is longer than in the case of classical forked strokes and c) the peak currents of the UI strokes are, usually, very small. From the visual inspection of the 35 selected events, 22 were classified as forked strokes and 13 UI strokes. A new name was given to the broad class of strokes that present two or more contact points in a millisecond and sub-millisecond scale, multi ground contact strokes (MGCS). Subclasses received the names forked strokes and UI strokes, related to the previous findings from the literature. All MGCS flashes were recorded during the summer season of 2013 in Southeastern Brazil as part of a five-day campaign employing a network of high-speed camera sensors known as the RAMMER network. The high-speed video records were obtained by three identical cameras installed in São José dos Campos and a fourth mobile camera (whose only difference from the other three is its capability to record colored images). All four cameras were set up for recording at 1200 x 500 pixels spatial resolution, 2500 frames per second, and 400-μs time interval between frames. A total of 357 negative CG flashes were recorded. The physical processes that generate either forked strokes and UI strokes are discussed in details. RAW data from BrasilDAT network was used to identify and give more information about the MGCS, such as: peak current estimates and precise interstroke intervals in the microsecond range. Plots of time intervals between strokes versus peak current added new information on the physical characteristics and distinctive features of UI and forked strokes. |
