    Lightning is quantified in the terms “flash” and “stroke”.  A lightning flash, which lasts approximately one fifth of a second, is comprised of hundreds of rapid strokes.  Lightning detection technology enables us to predict where lightning will strike up to a half an hour in advance.  The rate of travel of thunder has been measured at one mile every five seconds.
