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 US Weather Bureau's first experimental Doppler weather radar unit was obtained from the US Navy in the 1950s. Partly because of its common use by television meteorologists in on-air weather reporting, the specific term "Doppler Radar" has erroneously become popularly synonymous with the type of radar used in meteorology.
The Sea-Based X-Band Radar underway. The Sea-Based X-Band Radar ( SBX-1) is a floating, self-propelled, mobile active electronically scanned array early-warning radar station designed to operate in high winds and heavy seas. It was developed as part of the United States Department of Defense Missile Defense Agency's (MDA) Ballistic Missile ...
MPAR being installed in 2003. Multifunction Phased Array Radar (MPAR) was an experimental Doppler radar system that utilized phased array technology. MPAR could scan at angles as high as 60 degrees in elevation, and simultaneously track meteorological phenomena, biological flyers, non-cooperative aircraft, and air traffic.
Weather-sensing radar systems. Weather radars can resemble search radars. This radar uses radio waves along with horizontal, dual (horizontal and vertical), or circular polarization. The frequency selection of weather radar is a performance compromise between precipitation reflectivity and attenuation due to atmospheric water vapor.
A tornadic vortex signature, abbreviated TVS, is a Pulse-Doppler radar weather radar detected rotation algorithm that indicates the likely presence of a strong mesocyclone that is in some stage of tornadogenesis. [1] It may give meteorologists the ability to pinpoint and track the location of tornadic rotation within a larger storm, and is one ...
The state Department of Transportation closed the Kailua-bound right lane of Pali Highway after the second tunnel following a mudslide, and heavy rain led to the closure of Loop Road in Maunawili ...
Tethered Aerostat Radar System in New Mexico. The first aerostats were assigned to the United States Air Force in December 1980 at Cudjoe Key, Florida. During the 1980s, the U.S. Customs Service operated a network of aerostats to help counter illegal drug trafficking. Their first site was built at High Rock, Grand Bahama in 1984.
