Precipitation is water released from clouds in the form of rain, freezing rain, sleet, snow, or hail. It is the primary connection in the water cycle that provides for the delivery of atmospheric water to the Earth. Most precipitation falls as rain.
There are three different ways of turning moist air into cloud, so that it rains or snows. Rain-and other forms of precipitation-occur when warm moist air cools and condensation occurs. Since warm air can hold more water than cool air, when the warmer air is cooled the moisture condenses to liquid-and it rains. The video and text below explain how rain forms and the different types of rain that we get in the UK.
