《论衡·卷十四·寒温篇》
老百姓预测天气的寒温，多是今天寒冷明天温暖，早晨霜厚，晚上星光闪耀，早晨有雨气候温暖，早晨天晴气候寒冷。
民间占寒温，今日寒而明日温，朝有繁霜，夕有列光，旦雨气温，旦旸气寒。
When ordinary people predict changes in the weather, they often say that it will be cold today and warm tomorrow; that frost in the morning indicates twinkling stars at night; that rain in the morning indicates warmth; that a clear sky in the morning indicates coldness.
