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.).
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 ...
NSSL's first Doppler weather radar, the NSSL Doppler, located in Norman, Oklahoma. 1970s research using this radar led to NWS NEXRAD WSR-88D radar network. The first tornado captured on May 24, 1973, by the NSSL Doppler weather radar and NSSL chase personnel. The tornado is here in its early stage of formation near Union City, Oklahoma
A plan position indicator (PPI) is a type of radar display that represents the radar antenna in the center of the display, with the distance from it and height above ground drawn as concentric circles. As the radar antenna rotates, a radial trace on the PPI sweeps in unison with it about the center point. It is the most common type of radar ...
Mesoscale meteorology studies weather systems like thunderstorm clusters too small to be resolved by the earliest weather observation networks. The earliest networks of weather observations in the late 1800s and early 1900s could detect the movement and evolution of larger, synoptic-scale systems like high and low-pressure areas. However ...
The second planned project is the Bistatic Adaptable Radar Network (BARN) which will be integrated with existing DOWs and the COW to provide high resolution wind vector observations without the need for multiple, expensive transmitters. These bistatic receivers will consist of small antennas that can be deployed like Pods or mounted onto a ...
The center is staffed by scientists, engineers, technicians, and support personnel. [4] Key research areas include: [8] Climate (Earth's past, present, and future climate; the greenhouse effect, global warming, and climate change; El Niño, La Niña, and other large-scale atmospheric patterns; drought, wildfires)
In the early 1950s, the department received a 3-cm weather radar, AN/CPS-9, from the US Air Force. Using this 3-cm radar, researchers studied mid-latitude mesoscale systems, severe storms, and land-falling cyclones. [2] The AN/CPS-9 model was the first purpose-built weather radar. [3]
