bit + ( #A binary unit of information. )
afterglow + ( #A broad arc occasionally seen in the solar (as opposed to antisolar) sky during the darker half of [[civil twilight]] and, in principle, during nautical and [[astronomical twilight]]. )
beam + ( #A collimated source of [[electromagnetic radiation]] (e.g., a [[laser]] beam). )
air hoar + ( #A deposit of [[hoarfrost]] on objects above the earth's surface. )
analog + ( #A form of data [[display]] in which values are shown graphically. )

altitude + ( #A measure (or condition) of height, especially of great height, as a mountain top or aircraft [[flight level]]. )
black northeaster + ( #A northeasterly [[gale]] that occurs in southeast Australia in summer, with low pressure to the northwest and high pressure off the coast of New South Wales. )
biosphere reserves + ( #A protected area, or group of protected areas, set aside to support conservation of biological diversity and sustainable uses of terrestrial and coastal/marine ecosystems. )
arid zone + ( #A region with insufficient moisture where [[evaporation]] exceeds [[precipitation]]. )
break + ( #A sudden change in the weather; usually applied to the end of an extended period of unusually hot, cold, wet, or dry weather. )
advection fog + ( #A type of [[fog]] caused by the [[advection]] of [[moist air]] over a cold surface, and the consequent cooling of that air to below its [[dewpoint]]. )
air mass + ( #A widespread body of air, the properties … #A widespread body of air, the properties of which can be identified as 1) having been established while that air was situated over a particular region of the earth's surface ([[airmass source region|airmass source region]]), and 2) undergoing specific modifications while in transit away from the source region. An air mass is often defined as a widespread body of air that is approximately homogeneous in its horizontal extent, particularly with reference to [[temperature]] and moisture distribution; in addition, the vertical temperature and moisture variations are approximately the same over its horizontal extent. The stagnation or long-continued motion of air over a source region permits the vertical temperature and moisture distribution of the air to reach relative [[equilibrium]] with the underlying surface. ''See'' [[airmass classification]]. #In [[radiation]], the ratio of the actual path length taken by the direct solar [[beam]] to the analogous path when the sun is overhead from the top of the [[atmosphere]] to the surface. Extrapolation of surface measurements to zero air mass was the original method for estimating the value of solar [[irradiance]] at the top of the atmosphere. # ''See'' [[optical air mass]].[[optical air mass]]. )
backing + ( #According to general internationally accepted usage, a change in [[wind direction]] in a counterclockwise sense (e.g., south to southeast to east) in either hemisphere of the earth; the opposite of [[veering]]. )
aircraft ceiling + ( #After U.S. weather observing practice, the [[ceiling classification]] applied when the reported [[ceiling]] value has been determined by a pilot while in flight within one and one-half nautical miles of any runway of the airport. )
ash + ( #Airborne [[particulates]] produced as a combustion product. )
ablation + ( #All processes that remove [[snow]], [[ice]], or water from a [[glacier]], [[snowfield]], etc.; in this sense, the opposite of [[accumulation]]. )
bathy + ( #An abbreviation used informally for term … #An abbreviation used informally for terms such as "[[bathymetric chart|bathymetric]]," "bathythermal," or "[[bathythermograph]]." #In all uppercase (BATHY), the name of the World Meteorological Organization traditional alphanumeric code (TAC) form for reporting bathythermal observations. ([[Weather]] and oceanic data are communicated over national and international communications circuits as coded messages. Messages in TAC are broken into groups of related information, and BATHY is the shorthand used in TAC documentation to refer to the code form used for reporting a bathythermal observation.) #Derivative from meaning 2, bathy or BATHY is sometimes used informally to refer to a bathythermal observation in a context other than a TAC message.rmal observation in a context other than a TAC message. )
avulsion + ( #An abrupt change in the course of a [[stream]] or river, generally from one channel to a new one. )
brash + ( #An accumulation of [[floating ice]] fragments less than 2 m across, formed by breakage of other [[ice]] forms. )
boil + ( #An agitated zone of water, especially at the surface of a river, spring, or the sea, caused by upward turbulent movement. )
air pollution episode + ( #An extended period of a high concentration of pollutants in the [[atmosphere]]. )
base level of erosion + ( #An imaginary surface of irregular shape, inclined toward the lower end of the principal, or trunk, [[stream]] of a [[basin]], below which the stream and its tributaries were presumed to be unable to erode. )
