NEXRAD or Nexrad (Next-Generation Radar) is a network of 159 high-resolution S-band Doppler weather radars operated by the National Weather Service (NWS), an agency of the National Oceanic and Atmospheric Administration (NOAA) within the United States Department of Commerce, the Federal Aviation Administration (FAA) within the Department of Transportation, and the U.S. Air Force within the ...
The WSR-57 (Weather Surveillance Radar - 1957) was the first 'modern' weather radar. Initially commissioned at the Miami Hurricane Forecast Center, the WSR-57 was installed in other parts of the Contiguous United States (CONUS). [2] The WSR-57 was the first generation of radars designed expressly for a national warning network.
WSR-74. WSR-74C radar from Central Illinois WFO. WSR-74 radars were W eather S urveillance R adars designed in 1974 for the National Weather Service. They were added to the existing network of the WSR-57 model to improve forecasts and severe weather warnings. Some have been sold to other countries like Australia, Greece, and Pakistan.
This record is likely not one that Charleston officials are eager to break. The alert currently calls for 10-20 inches of rain, with higher amounts in certain local areas approaching 30 inches ...
During weather forecasts, WTAT features WCSC's own Collins ADC Doppler weather radar (known as "Live Super Doppler MAX") in addition to NOAA's National Weather Service radar images from several regional sites. Since January 1, 2016, WTAT's newscasts have been produced by WCIV. This change also came with a new anchor for the 10 p.m. news hour ...
A recent study by researchers at NOAA’s National Severe Storms Laboratory using Doppler Radar scans suggests the current methods of measuring tornadoes may be underestimating the twister's true ...
WCSC-TV began broadcasting on June 19, 1953. [2] Originally operating from studios located on East Bay Street in downtown Charleston, it was the second television station in South Carolina and the oldest continuously operating station in the state (the first was WCOS-TV in Columbia, which broadcast from May 1953 to January 1956).
Doppler effect. The emitted signal toward the car is reflected back with a variation of frequency that depends on the speed away/toward the radar (160 km/h). This is only a component of the real speed (170 km/h). The Doppler effect (or Doppler shift), named after Austrian physicist Christian Doppler who proposed it in 1842, is the difference ...
