1. Energy transferred from Earth's surface to the atmosphere through the evaporation and condensation processes.
2. If a change of state occurs from gas to liquid or liquid to solid, internal energy in the form of heat is released. If a change of state occurs from solid to liquid or liquid to gas, heat is required. Different compounds absorb and release different amounts of latent heat. Water takes nearly 600 kilocalories for each kilogram of water condensed.
Industry:Earth science
A thick ice formation with a fairly level surface, formed along a polar coast and in shallow bays and inlets, where it is fastened to the shore and often reaches bottom. It may grow hundreds of miles out to sea. It is usually an extension of land ice , and the seaward edge floats freely in deep water. The calving of an ice shelf forms tabular icebergs and ice islands. Also called shelf ice.
Industry:Earth science
A horizontal flow of water outward from a common center or zone, often associated with upwelling.

1. The electromagnetic radiation emitted by an ideal blackbody; it is the theoretical maximum amount of radiant energy of all wavelengths that can be emitted by a body at a given temperature. The spectral distribution of blackbody radiation is described by Planck law and the related radiation laws. If a tiny opening is made into an otherwise completely enclosed space (hohlraum), the radiation passing out through this hole when the walls of the enclosure have come to thermal equilibrium at some temperature will closely approximate ideal blackbody radiation for that temperature.
2. Any physical body absorbs and emits electromagnetic radiation when its temperature is above absolute zero. Planck's law determines the radiant flux of a body at a specific wavelength. In atmospheric chemistry, the calculation involving Earth's blackbody radiation shows that Earth's surface temperature would be below the freezing point of water if it did not have an atmosphere that absorbed some of the outgoing radiation.
Industry:Earth science
A type of fog produced from the advection of cold air over warm water or warm or moist land. This type of fog is sometimes called steam fog or sea smoke.
Industry:Earth science
Acoustic Ground Discrimination Systems detect the acoustic reflectance properties of seabed substrata that can be linked to the physical, or occasionally biological nature of the substrata, that can be useful in habitat mapping.
Industry:Earth science
A principal cloud type predominantly stratiform, in the form of a gray or whitish layer of patch, which nearly always has dark parts.
Industry:Earth science
A drag or tangential force imposed on Earth's surface by the motion of an adjacent body of air.
