Transcript of Lightning

Lightning 14 Different Types of Lightning Cloud-to-ground lightning discharged between a cumulonimbus cloud and the ground the greatest threat to ife and property since it hits the ground
initiated strike moving down from the cloud
known as the second most common type of lightning. Bead break up into a string of short, bright sections usually last longer than normal discharge channel
Theory 1: the width of the lightning channel varies; as the lightning channel cools and fades, the wider sections cool more slowly and remain visible longer, thus appearing a strong of beads.
Theory 2: observer sees portions of lightning channel ends on, that these portions appear especially bright. Staccato a short-duration stroke that appears as a single very bright flash and often branches. Forked exhibits branching of its path gound-to-cloud lightning discharge between a the ground and a cumulonimbus cloud initiated by an upward-moving leader stroke
much rarer than a cloud-to-ground lightning
forms when negatively charged ions called the stepped leader rises up from the ground and meets the positively charged ions in a cumulonimbus cloud, then return to the ground as a stroke.
cloud-to-cloud Lightning discharges may occur between areas of cloud without contacting the ground inter-cloud lightning: occurs between two separate clouds
intra-cloud lightning: occurs between areas of differing electric potential within a single cloud; most frequently occurring type.


sheet exhibits a diffuse brightening of the surface of a cloud caused by the actual discharge path being hidden. Heat lightning flash that appears to produce no thunder because it occurs too far away for the thunder to be heard The sound waves dissipate before they reach the observer Dry lightning that occurs with no precipitation at the surface most common natural cause of wildfires
