    How much rain a place gets, added up over a set period of time.

    示範例句 · Example

    We've had a long period of low rainfall this spring.

    逐字我們這個春天有一段長時間的低降雨量。

    「rainfall」是「一段時間裡、某個地方落下來的雨有多少」——氣象、地理課常講的「量」，單位常是毫米（mm）或英寸。核心畫面可以想成「雨的數量紀錄」，不是眼前正在下的那陣雨。rain 用在「下雨這件事」（It's raining）；rainfall 用在「雨下了多少」（annual rainfall、average rainfall）。可數／不可數都行，日常多半當不可數用。

core核心畫面

You can picture a measuring cup left outside all month: at the end, you look at the line the water reached. Rainfall is not the rain you feel on your face — it is how much of it landed, counted up.

可以想成一個量杯在外面放了一整個月，月底來看水停在哪一格。rainfall 講的不是打在臉上的那場雨，而是「落下來的雨累積起來有多少」，是被量出來的數字。
