Visibility such that objects are readily visible at a great distance.

Evaporation fog Fog produced when sufficient water vapor is added to the air by evaporation.
Evaporation Pan
In hydrologic terms, a pan used to hold water during observations for the determination of the quantity of evaporation at a given location. Such pans are of varying sizes and shapes, the most commonly used being circular or square.
Evaporation The process by which water changes phase from a liquid to a vapor at a temperature below the boiling point of water.
Evaporation Change from a liquid (more dense) to a vapor or gas (less dense) form. When water is heated it becomes a vapor that increases humidity. Evaporation is the opposite of condensation.
Evaporation- The process by which water molecules in liquid water escape into the air as water vapor.

Steam fog See Evaporation (mixing) fog.
Steppe An area of grass-covered, treeless plains that has a semi-arid climate.
CondensationThe process by which water vapor becomes a liquid; the opposite of evaporation, which is the conversion of liquid to vapor. In Australia, it is described as a change from a gas to a liquid.
Radio atmometer An instrument designed to measure the effect of sunlight on evaporation from plant foliage. It consists of a porous clay atmometer whose surface has been blackened so that it absorbs radiant energy.
They may also form from the evaporation of fog. Condensation nuclei, such as in smoke or dust particles, form a surface upon which water vapor can condense. CLOUD BANK A well-defined cloud mass that can be observed at a distance.
Closed BasinA basin draining to some depression or pond within its area, from which water is lost only by evaporation or percolation. A basin without a surface outlet for precipitation falling precipitation.
These properties are interconnected by the various physical processes such as precipitation, evaporation, infrared radiation, convection, advection, and turbulence.
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 sublimation of snow). The Bowen ratio ranges from about 0.
InterceptionIn hydrologic terms, the process by which precipitation is caught and held by foliage, twigs, and branches of trees, shrubs, and other vegetation, and lost by evaporation, never reaching the surface of the ground.
Most convective clouds are driven by positive buoyancy, with virtual temperature greater than the environment, but clouds with precipitation, evaporation, and/or melting can produce negatively buoyant convection. See slantwise convection. 3.
Latent Heat: Heat which is absorbed or released by a substance during condensation, evaporation or sublimation.
Latent Heating: In the atmostpere, heat which is moved from one place to another due to the changes of phases of water.

Ablation (1) Combined processes (such as sublimation, fusion or melting, evaporation) which remove snow or ice from the surface of a glacier or from a snow-field. Also used to express the quantity lost by these processes.
The lowest temperature that an air parcel would have if cooled adiabatically to saturation at constant pressure by evaporation of water into it, assuming that all latent heat required for evaporation would be supplied by the air parcel itself.
Even with the most intense precipitation, there is always lots of air around the falling raindrops or snowflakes and evaporation of the precipitation elements will occur.

Uplifted air on the windward side reaches saturation forming a cloud over the mountain crest, while subsiding or downslope winds on the leeward side warm and dry out the air, causing sufficient evaporation to abruptly terminate the cloud form.
The sea surface must be heated to about 27°C before evaporation is rapid enough to initiate a hurricane. Hurricanes begin in a tropical low-pressure area where cumulonimbus cluster in a region of high sea surface temperature.
