Description
Fresh snow in Colorado brings much needed moisture to the rocky mountains.
Snow falls in the form of flakes of crystalline water ice that fall from clouds. Since snow is composed of small ice particles, it is a granular material and has an open and therefore soft structure, unless subjected to external pressure. Snowflakes come in a variety of sizes and shapes; types that fall in the form of a ball due to melting and refreezing, rather than a flake, are known as hail, ice pellets or snow grains.
Snow tends to form within regions of upward movement of air around a type of low-pressure system known as an extratropical cyclone. It can fall poleward of these systems' associated warm fronts and within their comma-like shape of cloud precipitation patterns. Where relatively warm water bodies are present, water evaporation causes lake-effect snowfall that can become a concern downwind within the cold cyclonic flow around the backside of extratropical cyclones. Lake-effect snowfall can be heavy locally. Thundersnow is possible within a cyclone's comma head and within lake effect precipitation bands.
In mountainous areas, heavy snow is possible where upslope flow is maximized within windward sides of the terrain at elevation, if the atmosphere is cold enough. Snowfall amount and its related liquid equivalent precipitation amount are measured using a variety of different rain gauges.
