Snow comprises individual ice crystals that grow while suspended in the atmosphere—usually within clouds—and then fall, accumulating on the ground where they undergo further changes. It consists of frozen crystalline water throughout its life cycle, starting when, under suitable conditions, the ice crystals form in the atmosphere, increase to millimeter size, precipitate and accumulate on surfaces, then metamorphose in place, and ultimately melt, slide or sublimate away.
Snowstorms organize and develop by feeding on sources of atmospheric moisture and cold air. Snowflakes nucleate around particles in the atmosphere by attracting supercooled water droplets, which freeze in hexagonal-shaped crystals. Snowflakes take on a variety of shapes, basic among these are platelets, needles, columns and rime. As snow accumulates into a snowpack, it may blow into drifts. Over time, accumulated snow metamorphoses, by sintering, sublimation and freeze-thaw. Where the climate is cold enough for year-to-year accumulation, a glacier may form. Otherwise, snow typically melts seasonally, causing runoff into streams and rivers and recharging groundwater.
Major snow-prone areas include the polar regions, the northernmost half of the Northern Hemisphere and mountainous regions worldwide with sufficient moisture and cold temperatures. In the Southern Hemisphere, snow is confined primarily to mountainous areas, apart from Antarctica.
Snow affects such human activities as transportation: creating the need for keeping roadways, wings, and windows clear; agriculture: providing water to crops and safeguarding livestock; sports such as skiing, snowboarding, and snowmachine travel; and warfare. Snow affects ecosystems, as well, by providing an insulating layer during winter under which plants and animals are able to survive the cold
The UK recorded its coldest temperature since February 2019 on Tuesday after the mercury plummeted to lower than -12C in Scotland.
The Met Office told the Evening Standard a temperature of -12.3C was recorded on Tuesday evening at Loch Glascarnoch, near Inverness, making it the lowest minimum temperature since February 3, 2019 when a temperature of -12.7C was recorded at Cromdale, in the Scottish Highlands.
The lowest temperature recorded in 2020 was -10.2C at Dalwhinnie in Scotland on December 30.
But 2019 proved to be a colder year, with an even lower temperature of -15.4C recorded at Braemar on February 1, 2019.
It comes as the Met Office received reports of snow falling on the highest parts of the M25 and M26.
