measured amount of rain
The amount of rain that falls in a place during a certain time.
用法模式：
[amount] of rainfall in [place] during [time]
常见错误：
Learners sometimes say *"strong rainfall"* instead of *"heavy rainfall"*. In English, we talk about *heavy* or *light* rainfall, not *strong* or *weak* rainfall. Another mistake is using the plural *"rainfalls"* for normal situations; usually *rainfall* is uncountable, so we say *"high rainfall"*, not *"many rainfalls"*, except in technical or scientific writing.

Learners sometimes use *"rainfall"* in very everyday sentences where native speakers would normally just say *"rain"*, for example, *"I got caught in the rainfall"*. In casual speech, people usually say *"I got caught in the rain"* and use *"rainfall"* more in reports, news, or when talking about weather patterns.
