In general terms, precipitation is the condensation and falling out of any substance from a solution. More specifically, this is often used in meteorological terms to refer to water, in liquid or ice form, falling out of the atmosphere. The most common forms of precipitation consist of rain or snow, however precipitation also includes other frozen forms such as hail, sleet, graupel, freezing rain, etc. Precipitation is most often associated with fronts or low pressure areas , or with local convection. Precipitation which re-evaporates before reaching the ground is called virga.
