Four types of winter precipitation. While all forms of precipitation start as snow high up in the clouds, there are four primary types that eventually reach the ground: snow, sleet, freezing rain and plain ol' rain. Snow occurs when the atmosphere is cold all the way from the clouds to down here at the surface.
Snow is frozen precipitation, formed from ice crystals within clouds. Snow is normally pure, and like rain, provides a supply of fresh water. In cold climates, snow can compac â¦ t and refreeze into ice, forming massive glaciers as in Antarctica.
