What is precipitation?. Water that falls from the sky, it can be in different forms.. Hail, sleet, snow, rain.. Rain. As warm air rises into the atmosphere it cools. The air creates water vapor which condenses and forms into clouds. Once the clouds are big enough and are holding enough water it begins to rain.. Learning objectives.

PRECIPITATION GAUGE NETWORK. To have an idea of areal distribution of precipitation there should be adequately planned rain gauge network. There are two reasons to plan a network:. Catch area of a precipitation gauge is very small. Artificial rain making.. Process of Precipitation:. Precipitation is caused by condensation of water . vapours. of the air mass. . The ascending air mass with sufficient amount of water . vapours. becomes saturated due to adiabatic cooling.
