Channel branching and zigzagging in negative cloud-to-ground lightning |pdf=|usr=}}{{28615706}} gab.com Text Channel branching and zigzagging in negative cloud-to-ground lightning JO: Sci Rep http://www.kidney.de/pget.php?&tw=1&pmid=28615706 #FOAvip A fundamental question in lightning flash concerns why the discharge channel propagates in a zig-zag manner and produces extensive branches. Here we report the optical observation of two negative cloud-to-ground lightning discharges with very high temporal resolution of 180,000 frames per second, which shows in detail the dependence of channel branching and tortuous behavior on the stepping process of the leader development. It is found that the clustered space leaders formed in parallel ahead of the channel tip during an individual step process. The leader branching is due to the multiple connection of the clustered space leaders with the same root channel tip, which occur almost simultaneously, or successively as some space leaders/stems resurrect after interruption. Meanwhile, the irregularity of angles between the clustered space leaders and the advancing direction of leader tip is the origin of channel tortuosity. The statistical analysis on 96 steps shows a geometric-mean value of 4.4?m for the step length, ranging between 1.3 and 8.6?m, while the distance from the center of space leader to the channel is 3.6?m, ranging between 2.1 and 6.9?m. More than 50% steps occurred within an angle range of ±30° from the advancing direction of the leader.
