Up to thousands of points can be mapped for an individual lightning flash to reveal its location and the development of its structure. Lightning Mapping Arrays provide three-dimensional mapping of lightning channel segments near the array. What we do: NSSL uses the data collected by the NLDN to learn how storms produce CG flashes and how these flashes relate to other storm hazards. The +CG return stroke, however, more often has a sustained current that can have greater chance of igniting fires. Positive CG (+CG) flashes effectively bring positive charge to ground (or negative charge up) and almost always have only a single return stroke. CG flashes that bring negative charge from the cloud to ground (“negative CG” or “-CG”) can have multiple return strokes, which can sometimes be seen visually as a flickering of the channel to ground. Flashes outside of the network have larger location errors and may not even be detected.Įach system may detect more than one stroke (in-cloud or return) for a single lightning flash. Location accuracy is best when lightning occurs within a network of stations. Radio signals are detected by multiple stations (at least 3) are used to determine the location of the stroke by a time-of-arrival technique. Since there are many other sources of radio noise, the systems have to first identify which bursts are likely to be caused by lightning. CG return strokes usually have larger currents that make stronger signals that are easier to detect. A “stroke” can be a fast current within the cloud, or a “return stroke” in a channel to ground. These two systems work by detecting radio waves (sferics) emitted by fast electric currents (strokes) in lightning channels.
