A basin or region characterized by external drainage or draining to the ocean.
Industry:Weather
Influences on the earth's climate that originate outside the atmosphere or hydrosphere, for example, solar or cosmic radiation, variations in the earth's orbit, etc.
Industry:Weather
1. The region of diffluence at the downwind extremity of a jet stream; the opposite of entrance region. 2. Same as delta region.
Industry:Weather
A condensation trail that forms when the water vapor from fuel combustion of the aircraft engine is mixed with and saturates (or supersaturates) the air in the wake of the aircraft. Exhaust trails are of more common occurrence and of longer duration than aerodynamic trails.
Industry:Weather
1. In soil science, the process by which radioactive gases escape from the surface layers of soil or loose rock where they are formed by decay of radioactive salts. The exhalation of radioactive gases, notably radon and thoron, increases with soil temperature and so normally exhibits a single daily maximum around midday. Decreases of atmospheric pressure normally increase the exhalation, and freezing of the surface soil layers usually greatly reduces it. 2. The streaming forth of volcanic gases; also the escape of gases from a magnetic field.
Industry:Weather
1. The combined processes through which water is transferred to the atmosphere from open water and ice surfaces, bare soil, and vegetation that make up the earth's surface. 2. (Also called flyoff, water loss, total evaporation. ) The total amount of water transferred from the earth to the atmosphere. This is the most general term for the result of this composite process; duty of water and consumptive use have more specific applications.
Industry:Weather
Configurations of an atom or molecule that contain more energy than the ground state. Excited electronic or vibrational states usually occur following the absorption of radiation of the correct frequency, and are lost by processes such as emission of the radiation (fluorescence) or by reaction. Many electronically excited states are more reactive than the ground state, for example, the first excited state of atomic oxygen, O(1D).
Industry:Weather
The ratio of the turbulent flux of a conservative property through a surface to the gradient of the mean of the property normal to the surface. See diffusion, eddy flux, turbulence.
Industry:Weather
Volume resulting from rainfall at a rate greater than the infiltration rate. This term is used to describe effective precipitation.
Industry:Weather
Visibility such that objects are readily visible at great distance.
