  2. Freezing rain - Wikipedia

    en.wikipedia.org/wiki/Freezing_rain

    The red line shows how freezing rain forms, from snow through the warm layer and then into the "supercooled stage". Freezing rain is often associated with the approach of a warm front, when subfreezing air (temperatures at or below freezing) is trapped in the lowest levels of the atmosphere while warm air is advected aloft.

  3. Precipitation types - Wikipedia

    en.wikipedia.org/wiki/Precipitation_types

    Rain or drizzle which freezes on contact with a surface within a subfreezing air mass gains the preceding adjective "freezing", becoming the known freezing rain or freezing drizzle. 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 ...

  4. 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 ...

  5. Graupel - Wikipedia

    en.wikipedia.org/wiki/Graupel

    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 ...

  6. Diamond dust - Wikipedia

    en.wikipedia.org/wiki/Diamond_dust

    Falling diamond dust (Inari, Finland) Diamond dust is similar to fog in that it is a cloud based at the surface; however, it differs from fog in two main ways. Generally fog refers to a cloud composed of liquid water (the term ice fog usually refers to a fog that formed as liquid water and then froze, and frequently seems to occur in valleys with airborne pollution such as Fairbanks, Alaska ...

  7. Precipitation - Wikipedia

    en.wikipedia.org/wiki/Precipitation

    The relationship between snow height and water equivalent depends on the water content of the snow; the water equivalent can thus only provide a rough estimate of snow depth. Other forms of solid precipitation, such as snow pellets and hail or even sleet (rain and snow mixed), can also be melted and measured as their respective water ...

    An amber warning for snow and freezing rain covering most of Wales and central England is in place from 6pm on Saturday to midday on Sunday.. The second warning for snow, covering most of northern ...

  9. Accretion (meteorology) - Wikipedia

    en.wikipedia.org/wiki/Accretion_(meteorology)

    Accretion is defined as the gradual collection of something over time. [1] In meteorology or atmospheric science it is the process of accumulation of frozen water as precipitation over time as it descends through the atmosphere, in particular when an ice crystal or snowflake hits a supercooled liquid droplet, which then freeze together, increasing the size of the water particle.
