| 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 | moviment tal-arja |
| air pollutant | sustanzi li jniġġsu fl-arja |

| 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 | interazzjoni ajru-ilma |
| ambient air | arja ambjentali |
| civil air traffic Air traffic pertaining to or serving the general public, as distinguished from military air traffic | traffiku tal-ajru ċivili |

| 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 | interfaċċja arja-baħar |
