Scattered: Irregularly distributed over an area. Showers which while not widespread, can occur anywhere in an area. Implies a slightly greater incidence than isolated.
it is scattered in all directions. Of interest is the signal component received back at the radar. This signal is typically much weaker than the original sent from the transmitter and is called the "return signal".
Clear or Scattered Clouds (visibility greater than 10 mi.) Cb Cumulonimbus cloud, characterized by strong vertical development in the form of mountains or huge towers topped at least partially by a smooth, flat, often fibrous anvil.
backscattered radiationThe scattering of radiant energy into the hemisphere of space bounded by a plane normal to the direction of the incident radiation and lying on the same side as the incident ray.
Popcorn convectionClouds, showers and thundershowers that form on a scattered basis with little or no apparent organization, usually during the afternoon in response to diurnal heating.
When it strikes the target, a portion of the pulse will be back scattered towards the radar. If the target it strikes is well beyond the normal range of the radar, it will take longer for the back scattered energy to arrive back at the radar.
When the precipitation is convective in nature, the term scattered is used. See Precipitation Probability (PoP).
Scattered radiation Solar radiation scattered by particles in the atmosphere. Scattering coefficient A measure of the attenuation due to scattering of light as it traverses a medium containing scattering particles.
scattered or less) below 12,000 feet with no significant weather and/or obstructions to visibility.Station IDFive-digit WMO Station Identifier used by the Buoy Data Center since 1976.
2) With specific reference to zones of geomagnetic activity, "middle latitudes" refers to 20º to 50º geomagneticMie ScatteringAny scattering produced by spherical particles whose diameters are greater than 1/10 the wavelength of the scattered ...
BackscatterThe portion of power scattered back in the incident direction.BacksightIn hydrologic terms, a rod reading taken on a point of known elevation, a benchmark or a turning point.
In general the term is applied to Doppler radars operating in the VHF-UHF band (30 MHz- 3 GHz) that determine the wind by measuring the line-of-sight Doppler shift of scattered signals (Bragg scattering) from refractive index fluctuations caused by ...
The value of Z is a function of the amount of radar beam energy that is backscattered by a target and detected as a signal (or echo). Higher values of Z (and dBZ) thus indicate more energy being backscattered by a target.
If widely scattered, the drop size may be smaller. It is reported as "R" in an observation and on the METAR. The intensity of rain is based on rate of fall. "Very light" (R--) means that the scattered drops do not completely wet a surface.
If the transmitted radio signal reaches a target, then most of the energy is scattered, but some will be reflected back to the radar receiver. The presence of the target can be confirmed by the reflected signal.
The clouds themselves are not that color, they are merely reflecting the long (and unscattered) rays of sunlight which are predominant at those hours. The effect is much the same as if one were to shine a red spotlight on a white sheet.
Radar echo: The energy scattered back from a target and detected by the radar receiver. The amount of energy received by the radar is the reflectivity. Radiant energy. See Radiation ...
Echo - The energy received on radar that results from back-scattered energy; indicates the presence of precipitation (targets). EL - Equilibrium Level. The level where unstable air becomes stable again.
In meteorology, the signal from a weather radar unit is reflected and scattered from precipitation particles (rain, hail, snow) to determine the location, height and intensity of precipitation areas; ...
Diffused - Light Solar energy is scattered and reflected in the atmosphere and reaches Earth's surface in the form of diffuse blue light from the sky.
Large wavelets, crests begin to break, scattered whitecaps Leaves and small twigs constantly moving, light flags extended 4 ...
Radar echo Microwaves scattered or reflected by distant rain or snow back to a receiver where they are displayed as bright spots on a cathode ray tube.
Diffuse insolation Solar radiation that is scattered or reflected by atmospheric components (clouds, for example) to the earth's surface.
Haze - Tiny particles of dust, smoke, salt or pollution droplets that are scattered through the air. The particles are too small to be seen or felt individually, but they diminish visibility.
diffuse sky radiation: the energy from the sun that is scattered by molecules, clouds and aerosols in the atmosphere.
echo—In radar, (1) the energy reflected or scattered by a target; (2) the radar scope presentation of the return from a target.
A climate that has no monthly means above freezing and supports no vegetative cover except in a few scattered high mountain areas. This climate, with its perpetual ice and snow, is confined largely to the ice sheets of Greenland and Antarctica.
Stratus: The lowest clouds, generally found below 3000 metres altitude and often appearing as an overcast deck. Can also be found as scattered patches. Individual cloud elements have very ill-defined edges.
CH3 images use a mixture of back-scattered solar radiation plus radiation emitted by the earth and atmosphere. It is used in fog/very low cloud studies. Interpretation is sometimes complex, especially in the presence of other tropospheric clouds.
Beaufort force 3. Sustained wind speeds in the range of 7 to 10 knots. Large wavelets, crests begin to break; foam of glassy appearance, perhaps scattered white horses. Gravity wave ...
Shower - Intermittent rainfall of short duration that falls from a cumulus cloud. Heavy precipitation is possible. Implies more of a scattered rainfall.
Chance: A National Weather Service precipitation descriptor for 30, 40, or 50 percent chance of measurable precipitation (0.01 inch). When the precipitation is convective in nature, the term scattered is used.
A technique used to detect atmospheric constituents or related parameters such as atmospheric extinction coefficient. Light is produced in a modulated source and the resulting backscattered or reflected light is analyzed to quantify some property of ...
Rain Precipitation of liquid water particles, either in the form of drops of more than 0.5 mm in diameter, or of smaller widely scattered drops.
It forms an island between Java and Sumatra. Its eruption in 1883, which was one of the most violent in modern times, scattered debris and darkened skies over vast areas. Additional eruptions occurred in late 1927 and in the l960s.
The scattered thunderstorms that develop in the summer are called air-mass thunderstorms because they form in warm, maritime tropical air masses away from other weather fronts.
SCUD - Low broken clouds usually found beneath thunderstorm cloud bases, near fronts, or near cooler rain outflow regions. Common acronym for Scattered Cumulus Under Deck.
