Doppler Radar stationed in Lawrenceburg, Tennessee Tennessee Valley Weather employs a wide array of technology, including Baron Services Lynx, a Furuno WR2120 Dual Polarimetric Doppler weather radar , [ 9 ] [ 10 ] for which it founded the non-profit Tennessee Valley Weather Radar Foundation, [ 11 ] and a network of weather sensors and cameras.
A Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance. [1] It does this by bouncing a microwave signal off a desired target and analyzing how the object's motion has altered the frequency of the returned signal.
WLLX (97.5 FM) is a Class C2 FM radio station serving the southern Tennessee area. The station was one of the first in the nation to own and operate a live, color weather radar system and distribute the images to its listeners via a subcarrier on the primary FM signal.
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 (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 Alabama Huntsville [2] and led by Joshua Wurman, with the funding partially provided by the National Science Foundation ...
A NEXRAD weather radar currently used by the National Weather Service (NWS) is a 10 cm wavelength (2700-3000 MHz) radar capable of a complete scan every 4.5 to 10 minutes, depending on the number of angles scanned, and depending on whether or not MESO-SAILS [7] is active, which adds a supplemental low-level scan while completing a volume scan ...
A destructive tornado outbreak impacted the Midwestern United States and Tennessee River Valley on November 15, 2005. It occurred along a cold front separating warm, humid air from the southeast from cold Arctic air to the north and northwest. 49 tornadoes were confirmed in the central United States in the states of Alabama, Arkansas, Illinois, Indiana, Kentucky, Missouri and Tennessee over ...
Strong mesocyclone on a thunderstorm near Tuscaloosa, Alabama, that was analyzed as fitting the characteristics of a TVS.It was associated with a tornado.. 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.
