Snow
Snow comprises individual ice crystals that grow while suspended in the atmosphere. They then fall, accumulating on the ground where they undergo further changes. As snow accumulates into a snowpack, it may blow into drifts. Over time, accumulated snow metamorphoses, by sintering, sublimation and freeze-thaw.
About Snow in brief
Snow comprises individual ice crystals that grow while suspended in the atmosphere. They then fall, accumulating on the ground where they undergo further changes. 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. 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. A cold front, the leading edge of a cooler mass of air, can produce frontal snowsqualls—an intense frontal convective line when temperature is near freezing at the surface. A warm, moist air front can produce snow for a period, as it overrides the air-freezing air and boundary. Often snow transitions to rain in the warm sector behind the cold front. The same effect occurs over bodies of salt water, when it is uplifted by the orographic influence of higher elevations on the shores of higher water bodies. The ocean-effect bay-effect effect is enhanced when the moving air is lifted down by the wind. This can produce uplifted snow on the higher shores of sea bodies, which can also be called sea-effect snow. It is also known as the ocean- effect bay or bay effect when it uplifts the higher water on the shore, which is deposited on the colder air above.
It also occurs when it picks up water vapor from the lake, rises up through the cold air above, and freezes in the air above the lake. It can also occur when the warm air picks up the water vapor, which freezes above the air, and is deposited in the water above the water. It’s called the ocean effect bay effect or sea- effect snow when it lifts the water up and over the shore and onto higher ground. The effect is also called the sea effect bay- effect or bay- Effect when it boosts the temperature of the water, causing it to rise and freeze in the upper atmosphere. The water vapor is then carried up by the air to the surface, where it freezes and turns to ice. This is known as a lake effect snowstorm. Snowstorms organize and develop by feeding on sources of atmospheric moisture and cold air. The physics of snow crystal development in clouds results from a complex set of variables that include moisture content and temperatures. The resulting shapes of the falling and fallen crystals can be classified into a number of basic shapes and combinations thereof. 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 andcold temperatures. For the southern mid-latitudes, the side of a cyclone that produces the most snow is the southern side.
