The fallout of water drops or frozen particles from the atmosphere. Liquid types are rain and drizzle; frozen types are snow, hail, small hail, ice pellets (also called ice grains or, in the United States, sleet), snow pellets (graupel, soft hail), snow grains, ice needles, and ice crystals. In England, sleet is defined as a mixture of rain and snow or melting snow. Deposits of dew, frost (rime), and moisture collected from fog are occasionally also classed as precipitation.
