2011 New England tornado outbreak. On June 1, 2011, a total of six tornadoes touched down in both western Massachusetts and western Maine. The strongest was a long-track, high-end EF3 tornado that caused significant damage to the city of Springfield, Massachusetts as well as several adjacent cities and towns.
A recent study by researchers at NOAA’s National Severe Storms Laboratory using Doppler Radar scans suggests the current methods of measuring tornadoes may be underestimating the twister's true ...
Doppler effect. The emitted signal toward the car is reflected back with a variation of frequency that depends on the speed away/toward the radar (160 km/h). This is only a component of the real speed (170 km/h). The Doppler effect (or Doppler shift), named after Austrian physicist Christian Doppler who proposed it in 1842, is the difference ...
National Weather Service. The National Weather Service (NWS) is an agency of the United States federal government that is tasked with providing weather forecasts, warnings of hazardous weather, and other weather-related products to organizations and the public for the purposes of protection, safety, and general information.
This computer was the AN/AYK-8 design from the B-57G program, and designated AYK-8-EP1 for its much expanded memory. This radar also multiplexed a beyond-the-horizon (BTH) pulse mode that could complement the pulse-Doppler radar mode. This proved to be beneficial especially when the BTH mode is used to detect ships at sea when the radar beam is ...
The March 2017 North American blizzard also known as Winter Storm Stella was a major late-season blizzard that affected the Northeastern United States, New England and Canada, dumping up to 3 feet (36 in; 91 cm) of snow in the hardest hit areas, mainly New York, Vermont, New Hampshire and southern Quebec. Forming out of an extratropical cyclone ...
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 ...
Doppler on Wheels. DOW 7 on display at the USA Science and Engineering Festival in 2010. Doppler on Wheels (or DOW) is a fleet of X-band and C-band mobile and quickly-deployable truck-borne radars which are the core instrumentation of the Flexible Array of Radars and Mesonets [1] affiliated with the University of Illinois [2] and led by Joshua ...
