‘转晴’ is a compound verb meaning ‘to turn clear’—specifically describing a change in weather from cloudy, rainy, or overcast conditions to clear, sunny skies. The first character 转 (zhuǎn) means ‘to change’ or ‘to shift’, while 晴 (qíng) means ‘clear (weather)’ or ‘sunny’. Together, they form a compact, commonly used weather expression that emphasizes the transition itself—not just the resulting state.

This verb is frequently heard in weather forecasts, daily conversation, and news reports. It’s almost always used intransitively (no object), often with time expressions like ‘明天’ (tomorrow) or ‘下午’ (this afternoon), and commonly appears in structures like ‘要转晴’ (will turn clear) or ‘已经转晴了’ (has already turned clear). It conveys a sense of improvement and relief after gloomy weather, making it both functional and subtly positive in tone.
