Document Summary
Describe different types of lightning, and explain the sequence of events in a lighting strike. Most lightning discharges occur only in the clouds never striking the earth. this is called intracloud lightning. but sometimes it leaps out into the naked air, and so this phenomenon is called cloud-to-air lightning. After a strike, the main lightning channel begins to cool and sometimes decays into glowing fragments slow enough for the human eye to detect. this string of dots is called bead lightning or chain lightning. Sometimes lightning photographs have parallel successive flashes or strokes off-set from each other. In fact it"s entire existence is based solely off of reported public sightings. i scoured the internet and was only able to find one plausible photograph of ball lightning. Lightning from the anvil travels a longer distance, which can happen only if more volts. In canada, >90% of positive cg has single stroke (negative cg can have >10 strokes)
