ice formed by reverse sublimation of water vapour on cold surfaces.
- A phase change of water directly from ice to water vapor without melting.
sublimation—The change of (a) ice to water vapor or (b) water vapor to ice. See latent heat.
Chinook—A warm, dry joehn wind blowing down the eastern slopes of the Rocky Mountains over the adjacent plains in the U.S. and Canada.
The phase change from a solid to a gas. The opposite of crystallisation.
Sublimation: The transition of a substance from the solid phase directly to the vapour phase without being in the liquid phase. The opposite of sublimation is deposition.
The process of a solid (ice) changing directly into a gas (water vapor), or water vapor changing directly into ice, at the same temperature, without ever going through the liquid state (water). The opposite of crystallization.
sublimation - The process of phase transition from solid directly to vapor in the absence of melting. Thus an ice crystal or icicle sublimes under low relative humidity at temperatures below 0°C.
The process whereby ice changes directly into water vapor without melting.
Sublimation - The process whereby water changes phase from a solid into a vapor without first becoming liquid.
- The change from ice directly to water vapor or from water vapor to ice with out going through the liquid water phase.
sublimation- the change of ice to vapor or vapor to ice without a liquid phase.
- Phase change from a solid to a gas, without going through the liquid phase. Ice evaporating directly to water vapor is said to be "SUBLIMING". See also DEPOSITION.
Water vapor condensing over a cup of hot tea
Whenever a water molecule leaves a surface, it is said to have evaporated. Each water molecule that becomes water vapor takes a parcel of heat with it.
The process by which solids are transformed directly to the state of vapour or vice versa, without passing through the liquid phase.
Subtropical Ridge ...
ablation (glacial) All processes, which include melting, evaporation (sublimation), wind erosion, and calving (breaking off of ice masses), that remove snow or ice from a glacier or snowfield.
Bowen RatioFor any moist surface, the ratio of heat energy used for sensible heating (conduction and convection) to the heat energy used for latent heating (evaporation of water or of snow). The Bowen ratio ranges from about 0.
Examples include condensation and sublimation. LATITUDE The location north or south in reference to the equator, which is designated at zero (0) degrees. Parallel lines that circle the globe both north and south of the equator.
L'évapotranspiration comprend l'évaporation d'eaux libres (de l'océan, d'un lac, d'une rivière ou d'une autre surface de cours d'eau), la de l'eau solide (une surface de glace ou de neige) qui passe directement à ...
The rate of ice accumulation is slightly greater than the rate of sublimation. It is not hazardous even though de-icing/anti-icing equipment is not utilized, unless encountered for an extended period of time--over one hour.
A deposit of interlocking crystals formed by direct on objects, usually those of small diameter freely exposed to the air, such as tree branches, plants, wires, poles, etc.
Ice Fog Occurs when the temperature is much below freezing and water vapor condenses directly as ice crystals (sublimation).
The covering of ice crystals that forms by direct on exposed surfaces whose temperature is below freezing.
Old snow which has become granular and dense under the action of various processes of melting and refreezing, including sublimation.
fusion) is the amount of heat energy release to the environment when a gas changes its state to a liquid. For one gram of water, the amount of heat energy released is 540 calories at a temperature of 100 degrees Celsius. Latent heat of ...
Frost Heaving "Frost heaving" is the lifting of a surface by the internal action of frost. It generally occurs as a result of freeze-thaw cycles. It can also occur, to a lesser extent, by sublimation ...
