1. Same as antenna. 2. Of or pertaining to the air, atmosphere, or aviation.
Industry:Weather
(Also spelled eolian. ) Pertaining to the action or the effect of the wind, as in aeolian sounds or aeolian deposits (of dust); derived from the name of the Greek god of the winds, Aeolus, whose harp was held responsible for the murmur of the gentle breezes and whose conch-shell trumpet was regarded as the source of the gale's howl.
Industry:Weather
In general, any process whereby a substance becomes permeated with air or other gas; can be used synonymously with “ventilation. ”
This term refers to the formation and renewal of soil air.
Industry:Weather
A numerical forecast model based on discrete advection terms only, with less or no emphasis on forcing, dissipation, and physics. Advective models are most appropriately applied to nearly conserved quantities in the atmosphere or ocean, such as potential vorticity. Advective models are usually for one level only, or for a vertically integrated fluid. Historically, the barotropic model has been remarkably successful given its simplicity. A more recent example of an advective model is the divergent anomaly vorticity advection model.
Industry:Weather
The region of the atmosphere just above the tropopause, that is, the stratosphere. This term arose from the fact that this part of the atmosphere is relatively more stable than the troposphere, so that temperature changes at a point in it occur primarily by means of advection rather than by convection.
Industry:Weather
A thunderstorm resulting from instability produced by advection of relatively colder air at high levels, or relatively warmer air at low levels, or by a combination of both conditions.
Industry:Weather
A type of cold-air downslope flow at the bottom of the boundary layer where the two dominant processes are advection and buoyancy. Once fully developed, this idealized flow is constant in time as long as cold air is supplied or produced. Wind speed increases with the square root of downslope distance, and flow depth increases linearly with distance. Typical depths are 2–10 m. See katabatic wind, slope flow, gravity flow, drainage wind.
