In an aqueous solution, precipitation is the "sedimentation of a solid material (a precipitate) from a liquid solution". [ 1 ] [ 2 ] The solid formed is called the precipitate . [ 3 ] In case of an inorganic chemical reaction leading to precipitation, the chemical reagent causing the solid to form is called the precipitant .
All precipitation types are made up of hydrometeors by definition, including virga, which is precipitation which evaporates before reaching the ground. Particles blown from the Earth's surface by wind, such as blowing snow and blowing sea spray, are also hydrometeors , as are hail and snow .
Typical precipitation types associated with a warm front advancing over frigid air Precipitation in the form of a sunshower. In meteorology, the different types of precipitation often include the character, formation, or phase of the precipitation which is falling to ground level. There are three distinct ways that precipitation can occur.
Severe weather can occur under a variety of situations, but three characteristics are generally needed: a temperature or moisture boundary, moisture, and (in the event of severe, precipitation-based events) instability in the atmosphere.
Frozen precipitation particles, related to snow crystals Subclass Shape Physical process Graupel: Heavily rimed particles, spherical, conical, hexagonal or irregular in shape Heavy riming of particles by accretion of supercooled water droplets Hail: Laminar internal structure, translucent or milky glazed surface

Graupel (/ ˈ ɡ r aʊ p əl /; German: [ˈɡʁaʊpl̩] ⓘ), also called soft hail or snow pellets, [1] is precipitation that forms when supercooled water droplets in air are collected and freeze on falling snowflakes, forming 2–5 mm (0.08–0.20 in) balls of crisp, opaque rime. [2] Graupel is distinct from hail and ice pellets in both ...
A virga, also called a dry storm, is an observable streak or shaft of precipitation that evaporates or sublimates before reaching the ground. [1] A shaft of precipitation that does not evaporate before reaching the ground is known in meteorology as a precipitation shaft.
