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.).
The scale of dBZ values can be seen along the bottom of the image. Decibel relative to Z, or 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).

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 ...
Expect rainfall of 5 to 10 inches and local amounts up to 15 inches from Hurricane Helene. ... Radar images of Hurricane Helene. ... NWS radar Loop from Tampa Bay Area, FL.
A hook echo is a pendant or hook-shaped weather radar signature as part of some supercell thunderstorms. It is found in the lower portions of a storm as air and precipitation flow into a mesocyclone, resulting in a curved feature of reflectivity. The echo is produced by rain, hail, or debris being wrapped around the supercell. [1]
The upgrades also provided state of the art dual polarisation and doppler technologies. The CP in its title stands for cloud physics, and the radar has been used to research thunderstorms, drive improvements in rainfall measurements and hail detection and explore the potential for cloud seeding.

The first to launch with the initial rollout were Weatherscan Local (the primary service, offering a complete local weather segment every two minutes) and Weatherscan Radar (featuring a continuous 75-mile (121 km) Doppler radar loop, along with severe weather alerts when warranted).
