In viticulture, this term can have two meanings:


In meteorology, a common term for water that either falls to the earth in the liquid form of rain or thunderstorms and/or in the solid form of hail, sleet, drizzle or snow from clouds, or is deposited as surface precipitation directly by condensation (as in dew) or resublimation, i.e. the immediate transition of a substance from the gaseous to the solid state (as in frost) on objects such as the earth's surface. The amount of precipitation required in viticulture also depends on the respective soil conditions, such as water drainage and water storage capacity. The annual lower limit is at least 200 mm of precipitation; an average of 500 mm is required for quality viticulture and 750 mm in warmer climates with high evaporation.
