Thunder and lightning sounds have long been a staple of film, radio and stage productions because a storm instantly signals danger, tension or a change in mood without any explanation. As short video editing and meme culture grew, the same effect moved into online clips, where a three-second rumble and crack could set a scene or punctuate a joke. It remains popular because it is instantly recognisable across languages, including its Spanish name truenos y rayos, and because storm sounds work equally well for horror, drama, comedy and weather content.
