Covers the study of lightning, which is the electrical arc caused by the discharge of electrical charge that has built up between clouds and the ground or other clouds. Although lightning commonly refers to large-scale naturally occurring electrical discharges in the atmosphere, similar electrical arcs can be produced in the laboratory and may be relevant to this topic. Other electrical phenomena in the atmosphere, such as red sprites, elves, blue jets and ball lightning may be related enough for inclusion in lightning discussions.
