Editing Thunder (section)

Vavrek et al. (n.d.) reported that the sounds of thunder fall into categories based on [[loudness]], duration, and [[Pitch (music)|pitch]].<ref name = Vavreketaln.d. /> ''Claps'' are loud sounds lasting 0.2 to 2 seconds and containing higher pitches. ''Peals'' are sounds changing in loudness and pitch. ''Rolls'' are irregular mixtures of loudness and pitches. ''Rumbles'' are less loud, last for longer (up to more than 30 seconds), and are of low pitch.<ref>{{cite web |url=https://www.fastfactsforkids.com/weather-facts/thunder-facts-for-kids |title=Thunder Facts |publisher=Fast Facts for Kids |date=2022}}</ref>

Inversion thunder results when lightning strikes occur between the cloud and ground during a [[Inversion (meteorology)|temperature inversion]]. The resulting thunder sounds have significantly greater acoustic energy than those produced from the same distance in non-inversion conditions. In a temperature inversion, the air near the ground is cooler than the air higher up. Inversions often happen when warm, moist air passes above a cold front. Within a temperature inversion, sound energy is prevented from dispersing vertically as it would in non-inversion conditions, and is thus concentrated in the near-ground layer.<ref>{{cite web|author=Dean A.

Cloud-to-ground lightning (CG) typically consists of two or more return strokes, from ground to cloud. Later return strokes have greater acoustic energy than the first.<ref>{{cite web |url=https://www.nssl.noaa.gov/education/svrwx101/lightning/types/ |title=Lightning Types |publisher=NOAA National Severe Storms Laboratory |date=2022}}</ref>
