Temperature to which air must be cooled to become saturated with water vapor, assuming constant air pressure and water content.
When the temperature is below the freezing point of water, the dew point is called the frost point, as frost is formed via deposition rather than condensation.
Water frozen into a solid state, typically forming at or below temperatures of 0 degrees Celsius or 32 degrees Fahrenheit.
It is abundant on Earth's surface – particularly in the polar regions and above the snow line – and, as a common form of precipitation and deposition, plays a key role in Earth's water cycle and climate.
Thin layer of ice on a solid surface, which forms from water vapor in an above-freezing atmosphere coming in contact with a solid surface whose temperature is below freezing, and resulting in a phase change from water vapor to ice (a solid) as the water vapor reaches the freezing point.
Types of frost include crystalline frost (hoar frost or radiation frost) from deposition of water vapor from air of low humidity, white frost in humid conditions, window frost on glass surfaces, advection frost from cold wind over cold surfaces, black frost without visible ice at low temperatures and very low humidity, and rime under supercooled wet conditions.
Gaseous phase of water.
Deposition is a phase transition separate from condensation which leads to the direct formation of ice from water vapor.
Transition of a substance directly from the solid to the gas state, without passing through the liquid state.
The reverse process of sublimation is deposition or desublimation, in which a substance passes directly from a gas to a solid phase.
Garment worn to keep a human alive in the harsh environment of outer space, vacuum and temperature extremes.
Sweat evaporates readily in vacuum and may desublime or deposit on objects nearby: optics, sensors, the astronaut's visor, and other surfaces.
Genus of high cloud made of ice crystals.
Cirrus are usually formed when warm, dry air rises, causing water vapor deposition onto rocky or metallic dust particles at high altitudes.
Reverse of vaporization.
When the transition happens from the gaseous phase into the solid phase directly, the change is called deposition.
Concentration of water vapour present in the air.
At 100% relative humidity, air is saturated and at its dew point: the water vapor pressure would permit neither evaporation of nearby liquid water nor condensation to grow the nearby water; neither sublimation of nearby ice nor deposition to grow the nearby ice.
Solid form of carbon dioxide.
The opposite process is called deposition, where CO2 changes from the gas to solid phase (dry ice).
