Scattering The change in direction, frequency, or polarization of electromagnetic waves. See also Back scatter.
SCATTERING COEFFICIENT: A measure of the attenuation due to scattering of light as it traverses a medium containing scattering particles. SENSITIVITY: The ratio of the output of an instrument to the input (i.e. -gain).
Scattering The process by which small particles in the atmosphere deflect radiation from its path into different directions.
Scattering The process by which small particles disperse radiation in all directions. Scientific method A systematic form of inquiry that involves observation, speculation, and formulation and testing of hypotheses.
Scattering The process by which electromagnetic radiation interacts with and is redirected by the molecules of the atmosphere, ocean, or land surface.
Mie Scattering: Any scattering produced by spherical particles whose diameters are greater than 1/10 the wavelength of the scattered radiation. This type of scattering causes the clouds to appear white in the sky.

Rayleigh Scattering Changes in directions of electromagnetic energy by particles whose diameters are 1/16 wavelength or less. This type of scattering is responsible for the sky being blue. RCKY ...
The latitude belt roughly between 35 and 65 degrees North and South. Also referred to as the temperate region. or 2) With specific reference to zones of geomagnetic activity, "middle latitudes" refers to 20º to 50º geomagneticMie ScatteringAny ...
The sum of all backscattering cross-sections (e.g., precipitation particles) in a pulse resolution volume divided by that volume.
Radar ReflectivityThe sum of all backscattering cross-sections (e.g., precipitation particles) in a pulse resolution volume divided by that volume.
SCATTERING The process by which small particles suspended in the air diffuse a portion of the incident radiation in all directions. This is a primary reason for colors, such as blue skies, rainbows, and orange sunsets.
In scattering no energy transformation results, only a change in the spatial distribution of the radiation. Along with absorption, scattering is a major cause of the attenuation of radiation by the atmosphere.
scatteringThe process in which a beam of light is diffused or deflected by collisions with particles suspended in the atmosphere.
These radars depend on backscattering to produce a detectable echo from a target. Bistatic radars have the transmitter and its antenna at one location and the receiver and its antenna at a remote location.
Polarization RadarA radar which takes advantage of ways in which the transmitted waves' polarization affect the backscattering. Such radars may alternately transmit horizontal and vertically polarized beams, and measure differential reflectivity.
Radar Scattering: The process of radar energy being scattered by targets back to the radar. Radar Scope Ground Clutter: Echoes on the radar PPI Scope which indicates area of mountains, buildings, etc at a close range to the radar antenna.
The particles in fogs and clouds are much smaller, so they may show diffraction effects, as well as small-angle scattering in any case.
Attenuation - Any decrease in amplitude, density, or energy as result of an effect such as scattering, absorption, or friction. In physical meteorology, a reduction in radiation flow, especially solar radiation by atmospheric gases and aerosols.
(3) The blue scattering begins at around 25km (18 miles) up. The longer wavelengths, like red, continue more or less unimpeded to the surface (4). The blue light waves are scattered all over the sky up and down in all directions.
Tyndall Flowers (not botanical) John Tyndall was an English physicist who studied the scattering of light as it passed through smokey air, mist, fog and ice. He noted the effects of the differential radiative absorption and scattering by ice.
Radar- Stands for "radio detection and ranging." An instrument that detects and ranges distant objects by measuring the scattering and reflection of radio beams. Radiation- The transferring of energy through electromagnetic waves.
It marks the beginning of morning twilight. The visual display is created by the scattering of light reaching the upper atmosphere prior to the sun's rise to the observer's horizon. Related term: daybreak ...
A radar echo that is reflected, or scattered, at 180 degrees to the direction of the incident wave. Also the scattering of radiant energy into space before it reaches the earth's surface. BALL LIGHTNING ...
Seen from the side in a darkened room, the light beam from a projector appears blue, because of the smoke and dust in the air scattering the light. Resources and actions 1. Fill the bottle with water.
Thunder that originates further away has a more rumbling sound to it due to reflection, scattering and damping of the noise as it moves away from the source region into low level terrain. Sometimes, thunder is not heard altogether.
