-ics, -tics [-ac after i]
(Greek: a suffix that forms nouns and is usually used to form names of arts and sciences)
2. A reference to the study of clastic rocks or rock fragments broken by atmospheric weathering and recemented in the same pattern as the previous arrangement.
3. The fragments of rocks that are broken off in place by atmospheric weathering and which have been recemented without rearrangement.
Atmometrics involves the measuring of the evaporation of water from a free water surface; such as, a pan of water set into the ground so the water's surface is even with the ground's surface, or from a porous, water-saturated surface; such as, filter paper placed over a graduated cylinder of water.
2. The radio frequency electromagnetic radiation originating, principally, in the irregular surges of charge in thunderstorm lightning discharges.
Atmospherics are heard as a quasi-steady background of crackling noise (static) on certain radio frequencies; such as, those used to broadcast AM radio signals.
Since any acceleration of electric charge leads to emission of electromagnetic radiation, and since the several processes involved in propagation of lightning lead to very large charge accelerations, the lightning channel acts like a huge transmitter, sending out radiation with frequencies of the order of 10 kHz.
2. The study of the optical characteristics of the atmosphere or products of atmospheric processes.
The term is usually confined to visible and near visible radiation; however, unlike meteorological optics, it routinely includes temporal and spatial resolutions beyond those discernible with the naked eye.
Meteorological optics is that part of atmospheric optics concerned with the study of patterns observable with the naked eye./P>
This restriction is often relaxed slightly to allow the use of simple aids; such as, binoculars or a polarizing filter.
Topics included in meteorological optics are sky color, mirages, rainbows, halos, glories, coronas, and shines.
2. Atmospheric disturbances of electrical origin causing interference with communication in wireless telegraphy, television, etc.
3. Atmospheric conditions caused by electromagnetic disturbances; especially, as they affect radio transmission.
2. Of rock, fragmented in place by folding due to orogenic forces when the rock is not so heavily loaded as to render it plastic.
2. The science of flight dynamics and the trajectory of an object in free flight.
2. The field of medicine that offers treatment for the person who is overweight with a comprehensive program including diet and nutrition, exercise, behavior modification, lifestyle changes and, when indicated, the prescription of appetite suppressants and other appropriate medications.
Bariatrics also includes research into overweight, its causes, prevention, and treatment.
