2Rain, snow, sleet, or hail that falls to or condenses on the ground.
（雨、雪、雹等）降落；降水
these convective processes produce cloud and precipitation
count noun the heavy post-monsoon precipitations
Example sentencesExamples

- A potent threat to the environment of industrialized countries and their neighbors, acid rain occurs when precipitation picks up industrial chemicals as it falls to earth.

- Rain is the precipitation of condensed water vapor caused when a warm front meets a cold front in the upper atmosphere.
- Acid rain refers to any precipitation, rain or snow, that's more acid than ordinary rain or snow.
- If you have ever driven through dense precipitation such as rain, snow, sleet, or through fog, then you know the potential danger, especially when your vehicle is not equipped to face such conditions.
- Weather forecast: precipitation in the morning, rain in the afternoon.
- Eventually saturation occurs and precipitation falls and downdrafts occur.
- This means that as the annual number of days with precipitation will tend to fall, the possibility of convective rainfall leading to copious rainfall in torrential rains will increase.
- As air rises, it cools, and its humidity begins condensing into clouds and precipitation.
- The region has cool temperatures and frequent precipitation, fog, heavy cloud cover, and strong winds.
- And then it struck me that English does in fact distinguish precipitation from the stuff after it hits the ground.
- In places where the warmer air extends to the ground, the precipitation will fall as rain.
- So much rain has fallen that precipitation deficits from last year's drought have been eliminated.
Synonyms
frozen rain, hailstones, sleet
