Rainfall，英語名詞，音標為英[ˈreɪnfɔːl]/美[ˈreɪnfɔːl]，指代“降雨”或“降雨量”，複數形式為rainfalls。該詞通過“rain（雨）”與“fall（落下）”複合構成，自19世紀起廣泛套用於氣象學領域。
其核心內涵描述自然降水現象及量化指標，常見搭配如“monsoon rainfall”（季風降雨）、“rainfall intensity”（降雨強度）等，涵蓋降雨時長、分布及程度等維度，涉及氣候研究、農業規劃和水文分析等場景。專業術語體系套用中，該詞常與降雪量（snowfall）、降水量（precipitation）等氣象參數並列使用。
詞源可追溯至1839年，早期用於描述雨水的物理降落過程，伴隨氣象科學發展逐步演變為量化降雨數據的標準術語，現已成為氣候模型構建與環境評估的關鍵參數。
