Precipitation Precipitation In meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls under gravity. The main forms of precipitation include drizzle, rain, sleet, snow, graupel and hail. Precipitation occurs when a portion of the atmosphere becomes saturated with water vapor, so that the water condenses and "precipitates". Thus, fog and mist are not precipitation but suspensions, because the water vapor does not condense sufficiently to precipitate. Two processes, possibly acting together, can lead to air becoming saturated: cooling the air or adding water vapor to the air. Precipitation forms as smaller droplets coalesce via collision with
Hail Creek coal mine a result of severe monsoon rain force majeure was declared and not lifted at Hail Creek until May 2011. In February 2013, the operators of the mine were fined $2,200 for a breach of environmental guidelines when it released water from the mine. The relatively low penalty was criticised as a slap on the wrist.
