In hydrology, a line on a map connecting all points at which there exists an equal vertical distance between the earth's surface and the water table, or equal depths to the upper or lower surface of an aquifer.
Industry:Weather
A dense, hard soil layer that restricts the penetration of water and roots. It is formed by cementation of particles with sesquioxides, organic matter, silica, or calcium carbonate. The hardness does not change appreciably with changes in moisture content, and the soil does not slake in water.
Industry:Weather
1. An accumulation of broken river ice caught in a narrow channel. Ice jams during freeze-up are quite porous, whereas breakup jams may comprise solid flows, frequently producing local floods during a spring breakup. 2. Fields of lake or sea ice thawed loose from the shores in early spring and blown against the shore, sometimes exerting great pressures.
Industry:Weather
A constant-entropy chart; a synoptic chart presenting the distribution of meteorological elements in the atmosphere on a surface of constant potential temperature (equivalent to an isentropic surface). It usually contains the plotted data and analysis of such elements as pressure (or height), wind, temperature, and moisture at that surface.
Industry:Weather
A computer that shows the hourly travel distance of a vehicle under the influence of either a single or a complex set of velocity vectors. One of the primary functions of the computer is to facilitate flight planning by the wave-front method. A special type of computer has been designed to be used on 4D charts.
Industry:Weather
A colloidal system in which the dispersion medium is water. The dispersed phase may be a solid, a gas, or another liquid. Compare aerosol.
Industry:Weather
A collective term for the group of partially halogenated organic species, including the chlorofluorocarbons, hydrochlorofluorocarbons, hydrofluorocarbons, halons, methyl chloride, methyl bromide, etc. These compounds, some of which are naturally occurring (largely through production in the oceans) and some of which are of anthropogenic origin (use as solvents, foam blowing agents, refrigerants, etc. ), are the major source of the halogens (F, Cl, Br, I) to the stratosphere.
Industry:Weather
A code to report surface observations. References: 1) International synoptic codes FM 12-XI SYNOP Report of surface observations from a fixed land station; 2) FM 13-XI SHIP Report of surface observations from a mobile land station; and 3) FM 14-XI SYNOP MOBIL Report of surface observations from a mobile land station.
Industry:Weather
A code in which data on isobars and fronts at sea level (or earth's surface) are encoded and transmitted. It is a modified form of the international analysis code.
