heat lightning
English
[edit]Etymology
[edit]So called because it is common on hot summer nights and is sometimes popularly thought to be caused by heat rather storms.
Noun
[edit]- Lightning and/or thunder which the observer attributes to heat rather than a storm (e.g. because the storm/rain is too distant to be seen, or because there is no rain, as with dry lighting).

- The typical range at which thunder can be heard is around 24 km [...] Often, people mistakenly call lightning whose thunder is too far away to be heard "heat lightning," suggesting that the lightning somehow owes its existence merely to the heat of the day and not to a thunderstorm. Nonsense. "Heat lightning" is simply distant lightning whose thunder cannot be heard.
- (less commonly) Thunder that is heard without lightning being seen by the observer; heat thunder.
