Radar loop of the storm that produced the Marion, Illinois, tornado. On the 12:00 UTC surface chart, a cold front was draped from Minnesota southwest across Iowa, Kansas, Oklahoma, and into Texas. A triple point was found just south of Des Moines, Iowa, with a warm front positioned east across northern Illinois and Indiana.
A PX-1000 transportable radar unit operated by University of Oklahoma's Advanced Radar Research Center was used to observe the path of the tornado through Moore, with researchers detailing a "loop" in the path near the Moore Medical Center as a "failed occlusion". [37] EF3 May 28, 2013: Bennington, Kansas — — 264 mph (425 km/h)
Weather radar in Norman, Oklahoma with rainshaft Weather (WF44) radar dish University of Oklahoma OU-PRIME C-band, polarimetric, weather radar during construction. Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.).
A National Weather Service technician monitors Hurricane Carla on a WSR-57 radar on Sept. 10, 1961. (NOAA) For more than 60 years, Hurricane Carla has been the benchmark for landfalling hurricanes ...
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 ...
Winter Storm Cora is spreading a wintry mess of snow and ice across much of the South, including Atlanta and Charlotte. On this page, you'll find maps below that will help to track the storm.
The WSR-74 was introduced as a "gap filler", as well as an updated radar that, among other things, was transistor-based. [3] In the early 1970s, Enterprise Electronics Corporation (EEC), based out of Enterprise, Alabama won the contract to design, manufacture, test, and deliver the entire WSR-74 radar network (both C and S-Band versions).
The scale of dBZ values can be seen along the bottom of the image. dBZ is a logarithmic dimensionless technical unit used in radar. It is mostly used in weather radar, to compare the equivalent reflectivity factor (Z) of a remote object (in mm 6 per m 3) to the return of a droplet of rain with a diameter of 1 mm (1 mm 6 per m 3).
