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.
The University of Oklahoma's RaXPol mobile Doppler weather radar, positioned at a nearby overpass, measured winds preliminarily analyzed as in excess of 296 mph (476 km/h). These winds are considered the second-highest ever measured worldwide, just shy of the 321 mph (517 km/h) recorded during the 1999 Bridge Creek–Moore tornado .
The drought began on May 20, 2013, following the dissipation of the 2013 Moore, Oklahoma EF5 tornado. [11] [12] Several tornadoes since the Moore EF5 have reached the 200 miles per hour (320 km/h) wind speeds needed for a tornado to be classified as an EF5, including the 2013 El Reno EF3 tornado and 2015 Rochelle–Fairdale EF4 tornado, with wind speeds measured in excess of 295 miles per hour ...

Doppler radar analysis estimated that the supercell maintained a nearly continuous high-end rotational vorticity signature, averaging 94 mph (151 km/h; 82 kn) for approximately four hours and 20 minutes, a rarity among thunderstorms that produce mesocyclonic vorticity exceeding such speeds (averaging 1.5% of all supercells).
