  2. Ice pellets - Wikipedia

    en.wikipedia.org/wiki/Ice_pellets

    Ice pellets (Canadian English [1]) or sleet (American English) is a form of precipitation consisting of small, hard, translucent balls of ice. Ice pellets are different from graupel ("soft hail"), which is made of frosty white opaque rime , and from a mixture of rain and snow , which is a slushy liquid or semisolid.

  3. Rain and snow mixed - Wikipedia

    en.wikipedia.org/wiki/Rain_and_snow_mixed

    Rain and snow mixed (American English) or sleet (Commonwealth English) is precipitation composed of a mixture of rain and partially melted snow.Unlike ice pellets, which are hard, and freezing rain, which is fluid until striking an object where it fully freezes, this precipitation is soft and translucent, but it contains some traces of ice crystals from partially fused snowflakes, also called ...

  4. Sleet - Wikipedia

    en.wikipedia.org/wiki/Sleet

    Sleet is a regionally variant term for some meteorological phenomena: Ice pellets , pellets of ice composed of frozen raindrops or refrozen melted snowflakes (United States) Rain and snow mixed , snow that partially melts as it falls (United Kingdom, Ireland, Canada, and most Commonwealth countries)

  5. Precipitation types - Wikipedia

    en.wikipedia.org/wiki/Precipitation_types

    Slush is a mixture of both liquid and solid precipitation. Frozen forms of precipitation include snow, ice crystals, ice pellets (sleet), hail, and graupel. Their respective intensities are classified either by rate of precipitation, or by visibility restriction.

  6. Freezing rain - Wikipedia

    en.wikipedia.org/wiki/Freezing_rain

    Because freezing rain does not hit the ground as an ice pellet (called "sleet") but still as a rain droplet, it conforms to the shape of the ground, or object such as a tree branch or car. This makes one thick layer of ice, often called "glaze". Freezing rain and glaze ice on a large scale is called an ice storm. Effects on plants can be severe ...

  7. Snow - Wikipedia

    en.wikipedia.org/wiki/Snow

    An avalanche (also called a snowslide or snowslip) is a rapid flow of snow down a sloping surface. Avalanches are typically triggered in a starting zone from a mechanical failure in the snowpack (slab avalanche) when the forces on the snow exceed its strength but sometimes only with gradually widening (loose snow avalanche).

  8. Winter storm - Wikipedia

    en.wikipedia.org/wiki/Winter_storm

    The upward motion is called lift. [1] The moisture is collected by the wind from large bodies of water, such as a big lake or the ocean. If temperature is below freezing, 0 °C (32 °F), near the ground and up in the clouds, precipitation will fall as snow, ice, rain and snow mixed (sleet), ice pellets or even graupel (soft hail).

    Also actiniform. Describing a collection of low-lying, radially structured clouds with distinct shapes (resembling leaves or wheels in satellite imagery), and typically organized in extensive mesoscale fields over marine environments. They are closely related to and sometimes considered a variant of stratocumulus clouds. actinometer A scientific instrument used to measure the heating power of ...
