#electrical_discharge  a discharge of electricity
  supertype:  discharge  the sudden giving off of energy
  subtype:  nerve_impulse__nerveimpulse__impulse  the electrical discharge that travels along a nerve fiber; "they demonstrated the transmission of impulses from the cortex to the hypothalamus"
     subtype:  action_potential  the local voltage change across the cell wall as a nerve impulse is transmitted
  subtype:  spike.electrical_discharge  a transient variation in voltage or current
  subtype:  atmospheric_electricity__atmosphericelectricity  electrical discharges in the atmosphere
     subtype:  elves__elve  an acronym for Emissions of Light and Very low frequency perturbations due to Electromagnetic pulse Sources; extremely bright extremely short (less than a msec) electrical flashes forming a huge ring (up to 400 km diameter) in the ionosphere
     subtype:  blue_jets__jets  atmospheric discharges (lasting 10 msec) bursting from the tops of giant storm clouds in blue cones that widen as they flash upward
     subtype:  lightning  abrupt electric discharge from cloud to cloud or from cloud to earth accompanied by the emission of light

        subtype:  bolt_of_lightning__thunderbolt__bolt  a discharge of lightning accompanied by thunder
     subtype:  red_sprites__redsprite__sprites__sprite  atmospheric electricity (lasting 10 msec) appearing as globular flashes of red (pink to blood-red) light rising to heights of 60 miles (sometimes seen together with elves)
