1. Airborne particulates produced as a combustion product. These affect air quality, and their emission and ambient concentration is often regulated. For example, coal ash can consist of oxides of silicon, aluminum, iron, calcium, magnesium, sodium, potassium, sulfur, and titanium. 2. Airborne particulates produced by a volcano. These are often fine particles of rock with very sharp edges, which cause great abrasion and wear when ingested in the air intake of an engine, and can quickly lead to engine failure.
Industry:Weather
The northbound equatorial crossing of a polar-orbiting satellite, given in degrees longitude, date, and coordinated universal time (UTC) for any given orbit or pass; the point at which a satellite crosses the equatorial plane, heading north.
Industry:Weather
The negative of the gradient. The ascendent of a function is a vector with magnitude equal to the maximum spatial rate of change of that function at a given point at a given time. It is directed toward increasing values of the function along the line of maximum change and is represented by ∇F, where F is the function and ∇ is the del operator.
Industry:Weather
The process of artificially increasing the volume of water in the saturated zone by means of spreading water on the surface, injection wells, or inducing infiltration from streams or lakes.
Industry:Weather
Multidisciplinary field encompassing computer science, neuroscience, philosophy, psychology, robotics, and linguistics, and devoted to the reproduction of the methods or results of human reasoning and brain activity.
Industry:Weather
Generally, precipitation that is produced as a result of human activity, such as cloud seeding, in contrast to natural precipitation.
Industry:Weather
A man-made particulate aerosol used to induce the ice phase in cold (below 0°C) cloud seeding operations. Silver iodide aerosol is most commonly used.
Industry:Weather
A planar reflecting surface that can be adjusted to coincide with the astronomical horizon, that is, can be made perpendicular to the zenith. This instrument is used, usually in conjunction with others, in observing celestial bodies.
Industry:Weather
A well in which the water level is higher than the top of the aquifer.
Industry:Weather
