Snow rain

Snow is a type of precipitation in the Earth's atmosphere in the form of water ice Crystals, including a large number of snowflakes, the sulfur cloud. Because snow is composed of small ice particles, it is of bulk materials. It has an open, therefore soft structure, the packaging of foreign pressure. Snow came in different sizes and forms. Type in the form of balls, because the melting and re-freeze, than flakes, also known as sleet, ice and snow with corn as an example, graupel. Liquid equivalent snowfall and associated precipitation is determined to use a number of rain gauges.

Snow precipitation process is called snow. Snow is often formed in the region since the air motion around a sort of low-pressure system known as the extratropical cyclone. Decline in polar snow can be warm and the relevant aspects of its comma head precipitation patterns, which are called because of their comma-shaped cloud, and precipitation patterns over moderate and polar cyclones east and west sides; Relatively warm water areas exist, such as the evaporation of water lake, lake effect snow to become concerned about the lake of hot wind flow around the cold cyclone extratropical cyclone the butt. Lake-effect snow can be heavy local rain. Thundersnow can be first comma in cyclone within the lake effect precipitation zone. Mountains, heavy snow can increase the wind flow uphill in elevation of terrain during the parties, if the climate is cold enough.

Snow on the ground until it melts or sublimation. Snow direct sublimation of water vapor is most likely occur in dry and windy days, for example, when a strong downslope wind, such as the presence of Chinook winds. Water is equivalent to the amount of depth in a layer of snow the same quality of water and the upper region. For example, if the area is covered with snow water equivalent to 50 cm (20), it will melt into the pool of water 50 cm (20) deep covering the same territory. [38] This is a more useful tool than snow hydrology depth, density of the cold under the snow are just completely different. New snow density is generally about 8% water. This means that 33 cm (13) snow melt is 2.5 cm (1) water; [39] the physical process of cloud temperature and cloud effect in the form of individual snow crystals. High count or dendritic crystals tend to have more space between the arms to form snow ice, snow, and therefore the lower density, often referred to as "dry" snow. Conditions, columnar or tabular crystals greatly reduce the air space in crystals, so the density and feel "wet."
