When Irene was in England, she visited the transportation museum and was impressed with the large atmospheric steam engines on display.
The atmospheric entry is the penetration of human-made or natural objects from a planetary atmosphere by an object approaching from space, especially of the earth's atmosphere by a re-entering spacecraft.
The atmosphere protects life on Earth by absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night.
The radio frequency electromagnetic radiation originated 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.
Atmospheric inversion usually refers to an increase in temperature with increasing altitude, which is a departure from the usual decrease of temperature with height.In other words, atmospheric inversion is a reversal in the normal temperature lapse rate, the temperature rising with increased elevation instead of falling.
Usually, within the lower atmosphere (the troposphere) the air near the surface of the earth is warmer than the air above it, largely because the atmosphere is heated from below as solar radiation warms the earth's surface, which in turn then warms the layer of the atmosphere directly above it.
Atmospheric ionization is the production of ions in the atmosphere by the loss of an electron from a molecule, typically, for example, by cosmic rays or cosmic radiation.
Cosmic rays and radioactive decay are the main sources of atmospheric ionization.
Radioactivity at the surface can also produce ions in the lowest layer of the atmosphere.
While most often applied to the earth's atmosphere, the concept can be extended to any gravitationally supported ball of gas.
In other words, the atmospheric lapse rate involves the decrease of temperature with elevation in the atmosphere.
The "environmental lapse rate" is determined by the distribution of temperature in the vertical at a given time and place and should be carefully distinguished from the process lapse rate, which applies to an individual air parcel.
The atmospheric layer is one of several strata or layers of the earth's atmosphere.
Temperature distribution is the most common criterion used for denoting the various shells.
The term atmospheric optics 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.
With an increasing altitude, the atmospheric pressure decreases. For example, at 30,000 feet, approximately the height of Mt. Everest, the air pressure is 4.3 pounds per square inch.
The atmospheric pressure at any point in an atmosphere is due solely to the weight of the atmospheric gases above the point concerned.
