Atmosphere: The mass of air involving the Earth.
Atmospheric or Meteorological Tide: Periodic variation of the atmospheric pressure. It is much more significant in low latitudes.
The atmosphere is, of course, a compressible fluid, of low density and low viscosity, that obeys the ideal gas law to a good approximation.
In the atmosphere, diffracted light is actually bent around atmospheric particles -- most commonly, the atmospheric particles are tiny water droplets found in clouds. Diffracted light can produce fringes of light, dark or colored bands.
In the atmosphere, when a 'parcel' of air moves vertically upwards (or downwards), it cools (upward motion), or warms (downward motion), in accordance with thermodynamic rules ...
In the atmosphere, the Ekman spiral refers to how winds spiral to the right with height above the ground, as a result of the balance between the Coriolis, pressure gradient, and friction forces.
Standard atmosphere: a hypothetical vertical distribution of temperature, pressure and density which, by international consent, is taken to be representative of the atmosphere for purposes of pressure altimeter calibrations, ...
Standard atmosphere - a model of the atmosphere which represents an average for its temperature at various elevations.

Homosphere The atmosphere up to 80 km (50 mi) in which the proportionality of principal gaseous constituents, such as oxygen and nitrogen, is constant.
The term is used specifically to describe vertical transport of heat and moisture, especially by updrafts and downdrafts in an unstable atmosphere.
SATURATION POINT The point when the water vapor in the atmosphere is at its maximum level for the existing temperature. SCATTERED The amount of sky cover for a cloud layer between 3/8ths and 4/8ths, based on the summation layer amount for that layer.
Type II emissions occur in loose association with major FLAREs and are indicative of a shock wave moving through the solar atmosphere. Type III. Narrow-band bursts that sweep rapidly (seconds) from decimeter to dekameter wavelengths (500 - 0.5 MHz).
TranspirationWater discharged into the atmosphere from plant surfaces.Transport WindThe average wind over a specified period of time within a mixed layer near the surface of the earth.
Stable Boundary LayerThe stably-stratified layer that forms at the surface and grows upward, usually at night or in winter, as heat is extracted from the atmosphere's base in response to longwave radiative heat loss from the ground.
GEMPAKGeneral Environmental Meteorological Package (programming language)GENGeneralGeneral CirculationThe totality of large-scale organized motion for the entire global atmosphere.
A portable meteorological station used to provide weather data to the ALOHA air model that predicts how a cloud of pollutant gas might dispurse in the atmosphere after an accidental release. Also see CAMEO.
atmosphere - biosphere) of the carbon cycle. An examination of the carbon budget of a pool or reservoir can provide information about whether the pool or reservoir is functioning as a source or sink for CO2.
Hodograph: A polar coordinate graph which shows the vertical wind profile of the lowest 7000 meters of the atmosphere.
This dish has the capability to rotate 360 degrees in azimuth and up to 20 degrees in elevation allowing the radar to cover a huge volume of atmosphere.
This is also called the Lower Atmosphere Stability Index. It is computed from the morning (12Z) soundings from RAOB stations across North America. The index is composed of a stability term and a moisture term.
Any substance in the atmosphere that can be used to track the history of an air mass. It can be chemical or radioactive in nature. The main requirement for a tracer is that its lifetime be substantially longer than the transport process under study.

A term used to describe vertical motion in the atmosphere. The "omega equation" used in numerical weather models is composed of two terms, the "differential vorticity advection" term and the "thickness advection" term.
Greenhouse Effect - The atmosphere allows solar radiation to reach the earth relatively easily.
For the earth, this layer is considered to be roughly the lowest one or two kilometers of the atmosphere.
WAVE - A mechanical wave of energy moving though the atmosphere, very similar to a swell in the ocean. Commonly referred to as a TROUGH or SHORT WAVE. A TROPICAL WAVE is a trough like disturbance in the trade winds in tropical regions.

FRICTION LAYER The thin layer of atmosphere adjacent to the earth's surface. Surface friction is effective in slowing down wind up to approximately 1,500 to 3,000 feet above the ground. Above this level, air tends to flow parallel to the isobars.
In the atmosphere water vapor starts to condense on microscopic particles suspended in the air: dust, soot, volcanic ash, salt spray, etc. These are called cloud-condensation-nuclei.
