Atmospheric precipitate


Atmospheric sediment - products of water vapor condensation, fog droplet deposition and rain, appearing on cooled substrates (soil, plants, objects). Atmospheric sediments are those that form only on the surface of solids, while the forms appearing on surfaces as a result of gravitational precipitation are called atmospheric precipitation. Atmospheric precipitation can occur as a result of water vapor precipitation or atmospheric precipitation. Atmospheric precipitations are part of meteorological phenomena.

The most common are: solid residues szadź hoarfrost zamróz

Flotation - a rash that occurs on sloping and vertical surfaces in the form of falling and falling water droplets. It is caused by the inflow of warm and humid air to the cooled walls of buildings or rocks. Appears from windward side.

Rosa - sediment in the form of water droplets formed on the surface of rocks, plants and other objects by the condensation of water vapor contained in the air. Occurs when the air is cooled below the dew point, usually in the evening. Frost - a precipitate whose mechanism of formation is similar to the formation of dew, differs only in thermal conditions - occurs at the negative air temperature. It is made of fine ice crystals in the form of needles. The condition of frost formation is to lower the substrate temperature below the triple point temperature for water and the partial vapor pressure in the air below the triple water pressure point. There is a direct exchange of steam into a solid, ie resublimation.

Shad - an intermediate form between frost and freezing or glazing, most often takes the form of ice bristles, ice crystals stuck with freezing fog. Occurs when moist air containing small droplets of supercooled water (mist) flows into an area of ​​often lower temperature. Then, on the exposed surfaces, ice needles (see frost) begin to rise in the direction of the cold and humid air. These needles are clustered by freezing water droplets, resulting in distinctive brushes. The amount of sludge can be so great that it causes the breaking of the branches of the trees.

Gołoledź - a precipitate in the form of a smooth, even, transparent layer of ice, covering the substrate. Occurs when the rain (or mist) falls on a substrate with a temperature less than zero. Falling droplets melt and freeze. Glaucoma occurs most often when, after freezing and dry weather, warming occurs, which also results in precipitation or freezing of a thin layer of water covering the surface. This is a very dangerous phenomenon, especially for road users.

When glazing over a thin layer of objects (especially the surface of an asphalt road), it seems particularly black, this kind of iceberg is called black ice.

Solids - appearing in the same places as liquid splashes if the rock or walls of buildings have temperatures below 0 ° C.
