Rain and thunder recordings have been a staple of ambient sound libraries and relaxation content for decades because the combination masks distractions while still feeling alive and natural. Online, this type of clip spread through sleep playlists, meditation channels, ASMR videos, and lo-fi study streams, where listeners keep it looping for hours. Creators also use it as an instant weather cue in animations, games, and short films, since a single thunder roll tells the audience a storm is present without any visual effects or dialogue needed.
