| Description | A complete lightning discharge (called a “flash”) consists of many diverse transient processes that generate high-level electromagnetic signals in the vicinity of the flash over a typical period of 0.5 s (Uman, 1969; Golde, 1977). In a ground flash, shown schematically in Figure 1, this activity starts with a large number of physi cally short, brief, transient, probing processes that occur within the cloud for some time before the return stroke. The stepwise propagation of the many leaders follows, at least one of which reaches the ground, resulting in the dramatic return stroke, which carries currents of tens or hundreds of kiloamperes along the kilometers-long cloud-to-ground channel. Once the conducting channel to the cloud is established, additional leaders and return strokes (on the average, four or five) generally occur (leading to the flickering appearance of lightning).
