These particles form a space charge surrounding the channel. After the leader reaches the earth, the return stroke occurs from earth to cloud. When this develops, the space charge tends to migrate rapidly to the channel, »roducing a rush of charces within it. The flow of these charges in the channel yields the 8 stroke. ithin the channel brilliant, return lightning ion is exceeding heavy. Fea} - ai | TOR, RIE SAS) » Rae ama Pe WAU heS FRMALGN.
