Linear Radar Echoes squall lines on radar images
Radar indicates the linear nature of a squall line. The strongest radar reflectivity (VIP) levels on the leading edge reveal the locations of updrafts and adjacent regions of heavy precipitation.
radar echo"See echo.
radar equation"An equation expressing the power of a radar echo at the input of the receiving antenna of a radar as a function of the range and radar cross section of a target.
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 ...
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.
radar echo—See echo.
radarsonde observation—A rawinsonde observation in which winds are determined by radar tracking a balloon-borne target.
Radar echoes caused by birds, insects, and localized refractive index discontinuities.

Radar echoes that interfere with observation of desired signals on the radar display.

A radar echo which is linear but bent outward in a bow shape. Damaging straight-line winds often occur near the "crest" or centre of a bow echo.
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.

Angels Radar echoes caused by birds, insects, and localized refractive index discontinuities.
Annual Flood The maximum discharge peak during a given water year (October 1 - September 30).
BOW ECHO
A radar echo signature often associated with severe thunderstorms, especially those that produce wind damage. It is bent outward in a "bow" shape.
Clutter: Radar echoes that interfere with observation of desired signals on the radar display.

BACKSCATTER 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.
BOVCBase of OvercastBow EchoA radar echo which is linear but bent outward in a bow shape. Damaging straight-line winds often occur near the "crest" or center of a bow echo.
Radar Echo:Electromagnetic waves scattered back to the radar receiver and displayed on the PPI Scope from targeted precipitation.
Radar Ground Clutter: Reflection from trees, buildings, hills in close around the radar.
Ground Clutter - a pattern of radar echoes from fixed ground targets (buildings, hills, etc.) near the radar.
The term "cell" also is used to describe the radar echo returned by an individual shower or thunderstorm. Such usage, although common, is technically incorrect.
Chaff typically produces a radar echo which closely resembles precipitation. Chaff drops once were conducted by the military in order to confuse enemy radar, but now are conducted mainly for radar testing and calibration purposes.
Spiral Band
The characteristic arrangement of radar echoes in the intense echo region surrounding the "eye" of a hurricane, a typhoon or a tropical storm, which allows the storm center to be located.
ECHO The energy return of a radar signal after it has hit the target. Related term: radar echo
ECLIPSE The obscuring of one celestial body by another. Related terms: lunar eclipse and solar eclipse ...
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; comparison of multiple radar echoes permits ...
VIP - Video Information Processor. A video color code given to a radar echo from 0 to 6. VIP 0 is the lightest and level 6 is the worst. Used mostly for the aviation community.
LimnologyIn hydrologic terms, the branch of hydrology that pertains to the study of lakesLine Echo Wave Pattern(abbrev. LEWP) A radar echo pattern formed when a segment of a line of thunderstorms surges forward at an accelerated rate.
Spearhead EchoA radar echo associated with a downburst with a pointed appendage extending toward the direction of the echo motion. The appendage moves much faster than the parent echo, which is drawn into the appendage.
