‘骤雨’ literally combines 骤 (zhòu), meaning ‘sudden’ or ‘abrupt’, and 雨 (yǔ), meaning ‘rain’. Together, it refers to a brief, intense downpour that begins and ends quickly—often without warning—like a summer thunderstorm. It emphasizes the sudden onset and short duration, not just heavy rain. The word carries a poetic or literary tone and appears frequently in classical and modern Chinese poetry, weather reports, and descriptive writing.

Unlike general terms like ‘大雨’ (heavy rain) or ‘暴雨’ (torrential rain), ‘骤雨’ highlights unpredictability and brevity. It’s commonly used when describing natural scenes—such as rain falling on leaves, streets, or mountains—or evoking mood shifts (e.g., sudden calm after the rain). Though neutral in register, it’s rarely used in casual spoken Mandarin; speakers often say ‘阵雨’ (zhèn yǔ, ‘shower’) instead for everyday contexts.
