26Air pollution in British Columbia — Air pollution is a concern in British Columbia (BC), Canada because of its effects on health and visibility. Air quality is influenced in BC by numerous mountain ranges and valleys, which complicate atmospheric pollution dispersion and can lead… …
27Atmospheric instability — is a condition where the atmosphere is generally considered to be unstable and as a result the weather is subject to a high degree of variability through distance and time [ [http://www.ace.mmu.ac.uk/eae/Weather/Older/Stability of Air.html… …
28Air sensitive — is a term used, particularly in chemistry, to denote compounds that react with air; typically with atmospheric oxygen (O2) or atmospheric water (H2O), although reactions with the other constituents of air such as carbon monoxide (CO), carbon… …
29Air-independent propulsion — (AIP) is a term that encompasses technologies which allow a submarine to operate without the need to surface or use a snorkel to access atmospheric oxygen. The term usually excludes the use of nuclear power, and describes augmenting or replacing… …
30Atmospheric moisture extraction — removes water vapor from air for drinking, cleaning, and other uses. Some foggy neighborhoods in Lima, Peru are using fog nets to harvest moisture as an alternative to scarce natural rainfall.[1] A famous fictional depiction is the moisture farms …
