| aire de residus | waste air Exhaust or gaseous air given off by any industrial, manufacturing or chemical process |
| aire respiratori | respiratory air Air volumes inspired and expired through the lungs |
| biologia de l'aire | aerobiology The study of the atmospheric dispersal of airborne fungus spores, pollen grains, and microorganisms; and, more broadly, of airborne propagules of algae and protozoans, minute insects such as aphids, and pollution gases and particles which exert specific biologic effects |
| condicionament de l'aire | air conditioning A system or process for controlling the temperature and sometimes the humidity and purity of the air in a house, etc. |
| control de la qualitat de l'aire | air quality control The measurement of ambient air-pollution concentrations in order to determine whether there is a problem in a given region |
| interacció aire-aigua | air-water interaction The physical processes at the air-water interface: momentum, heat and mass transfer across the air-water interface, mixing of surface water by wind stress and wave breaking, directional wave spectra and wave forces on offshore structures. The air-water interaction is measured by the turbulence and gas exchanges resulting from the mixing of the water column by wind |
| interfície oceà-aire | ocean-air interface The sea and the atmosphere are fluids in contact with one another, but in different energy states - the liquid and the gaseous. The free surface boundary between them inhibits, but by no means totally prevents, exchange of mass and energy between the two. Almost all interchanges across this boundary occur most effectively when turbulent conditions prevail. A roughened sea surface, large differences in properties between the water and the air, or an unstable air column that facilitates the transport of air volumes from sea surface to high in the atmosphere. Both heat and water (vapor) tend to migrate across the boundary in the direction from sea to air. Heat is exchanged by three processes: radiation, conduction, and evaporation. The largest net exchange is through evaporation, the process of transferring water from sea to air by vaporization of the water |
| moviment de l'aire | air movement Air movements within the Earth's atmospheric circulation; also called planetary winds. Two main components are recognized: first, the latitudinal meridional component due to the Coriolis force (a deflecting motion or force discussed by G.G. de Coriolis in 1835. The rotation of the Earth causes a body moving across its surface to be deflected to the right in the N hemisphere and to the left in the S hemisphere); and secondly, the longitudinal component and the vertical movement, resulting largely from varying pressure distributions due to differential heating and cooling of the Earth's surface |
| ordenament de la qualitat de l'aire | air quality management Regulate and plan and work toward the accomplishment of completion of stated goals, objectives and mission pertaining to air quality |
| purificació d'aire de residus | waste air purification gas (gas) |
| qualitat de l'aire | air quality The degree to which air is polluted; the type and maximum concentration of man-produced pollutants that should be permitted in the atmosphere |
| temperatura de l'aire | air temperature The temperature of the atmosphere which represents the average kinetic energy of the molecular motion in a small region and is defined in terms of a standard or calibrated thermometer in thermal equilibrium with the air |
| vigilància de la qualitat de l'aire | air quality monitoring Regular checking and recording of air quality in a given area. The following pollutants must be considered: carbon monoxide, benzene, butadiene, lead, sulphur dioxide, nitrogen dioxide, and particulates |
| zona d'aire net | clean air area Areas where significant reductions in ozone forming pollutants have been achieved through industrial initiatives to control and/or prevent pollution, through implementation of transportation improvement plans, national efforts to reduce automobile tailpipe emissions and lower the volatility (evaporation rate) of gasoline |
