Hail is a chunk of ice that can fall during thunderstorms. Unlike snow, sleet, freezing rain, and graupel, which occur in colder weather, hail is most common in warm conditions, during spring and ...
Freezing rain develops when falling snow encounters a layer of warm air aloft, typically around the 800 mbar (800 hPa; 80 kPa) level, causing the snow to melt and become rain. As the rain continues to fall, it passes through a layer of subfreezing air just above the surface and cools to a temperature below freezing (0 °C or 32 °F or 273 K).
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 ...
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 ...
Ice storms are often associated with freezing rain, which can occur when snowflakes that melted in the air supercool in a layer of cold air just before hitting the ground, freezing nearly ...
While snowfall is rare, when the needed conditions align, cities such as Houston, New Orleans, Jacksonville and Savannah can experience frozen precipitation, often in the form of sleet and ...
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 ...
While snow levels will tend to spend considerable time above pass level with each storm, there will be periods when temperatures are below freezing and snow is falling and creating wintry travel ...
