The semipermanent, semicontinuous front between the deep, cold arctic air and the shallower, basically less cold polar air of northern latitudes; generally comparable to the antarctic front of the Southern Hemisphere.
Industry:Weather
“Any area in the high latitudes dominated by bare rocks, ice, or snow, and having a sparse vegetation and a low annual precipitation. ”
Thus stated, this includes portions of both ice cap and tundra regions of both hemispheres. The term barrens is sometimes used, but this has more general application.
Industry:Weather
A type of air mass with characteristics developed mostly in winter over arctic surfaces of ice and snow. Arctic air is cold aloft and extends to great heights, but the surface temperatures are often higher than those of polar air. For two or three months in summer arctic air masses are shallow and rapidly lose their characteristics as they move southward. See also antarctic air, airmass classification.
Industry:Weather
The statement that a net upward or buoyant force, equal in magnitude to the weight of the displaced fluid, acts upon a body either partly or wholly submerged in a fluid at rest under the influence of gravity. This force is known as the Archimedean buoyant force (or buoyancy), is independent of the shape of the submerged body, and does not depend upon any special properties of the fluid.
Industry:Weather
A luminous, gaseous, electrical discharge in which the charge transfer occurs continuously along a narrow channel of high ion density. An arc discharge requires a continuous source of an electric potential gradient across the terminals of the arc. Arc discharges do not naturally occur in the atmosphere. Compare corona discharge, point discharge, spark discharge.
Industry:Weather
A geologic formation that has no interconnected openings and hence cannot receive or transmit water.
Industry:Weather
A test to determine hydrologic properties of the aquifer involving the withdrawal of measured quantities of water from, or addition of water to, a well and the measurement of resulting changes in head in the aquifer both during and after the period of discharge or additions.
Industry:Weather
A layer of saturated geologic materials that could yield water to springs or wells.
Industry:Weather
A group of two or more aquifers that are separated by aquitards or aquicludes.
Industry:Weather
A field of study where weather data, analyses, and forecasts are put to practical use. Examples of applications include environmental health, weather modification, air pollution meteorology, agricultural and forest meteorology, transportation, value-added product development and display, and all aspects of industrial meteorology. Compare applied climatology.
