In 2002, Bay News 9 was the first TV station in the area to provide a VIPIR Doppler weather radar system. In 2007, Bay News 9 became the first station in Florida, and one of only a handful of stations, to provide a Dual-Pole Doppler Radar system. On Monday, January 5, 2009, Bay News 9 launched its upgraded doppler radar system called Klystron 9 ...
A klystron is a specialized linear-beam vacuum tube, invented in 1937 by American electrical engineers Russell and Sigurd Varian, [1] which is used as an amplifier for high radio frequencies, from UHF up into the microwave range. Low-power klystrons are used as oscillators in terrestrial microwave relay communications links, while high-power ...
The Canadian weather radar network consists of 33 weather radars spanning Canada's most populated regions. Their primary purpose is the early detection of precipitation, its motion and the threat it poses to life and property. Each had until 2018 a range of 256 km (159 mi) in radius around the site to detect reflectivity, 3 angles with a range ...
Upon publication of a paper in 1939, [21] news of the klystron quickly influenced the work of US and British researchers working on radar technology. Thereafter, klystron equipment was set up in Boston in 1939, and with it, successful blind-landing tests of airplanes were completed. [ 19 ]
The H2S design team did not believe the klystron could do the job, and tests of an H2S built with klystrons showed a drop in output power by a factor of 20 to 30. At the same altitude, the klystron powered versions were able to detect a town at 10 miles (16 km) while the magnetron version was capable of 35 miles (56 km).
Morgan was kidnapped around 10:45 p.m. on June 9, 1995, from the Alma Little League ballfield parking lot, the Alma Police Department said Tuesday while updating community members on the case.
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 National Weather Service issued its first tornado warnings — for northern Chatham County and central Orange County — at 10:38 a.m. Friday, spawning a frenzy of weather updates.
