The higher the BTI value is, the more likely a tornado is on the ground. Shear markers from different colors are used with BTI values above 2. Yellow markers are used for values between 2 and 3.9, Orange markers are used for values between 4 and 6.9 and red markers are used for values over 7. [4]
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.
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 ...
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 ...

The primary Lubbock tornado – the second of two tornadoes that struck the city on May 11 – produced a damage path 8.5 mi (13.7 km) long and extending across 15 sq mi (39 km 2) of ground, beginning at 9:35 p.m. in southwestern Lubbock, tracking through downtown Lubbock, and lifting shortly after 10 p.m. near the Lubbock Municipal Airport [6 ...
The radar suffers beam blockage on the tilts 0.6° and 0.83° to the W and SW of the radar, leading to an under-representation of reflectivity values between those bearings. Mornington Island 16°40′S 139°10′E / 16.67°S 139.17°E / -16.67;
