The Rapid X-band Polarimetric Radar, commonly abbreviated as RaXPol, [1] is a mobile research radar designed and operated by the University of Oklahoma, led by Howard Bluestein. RaXPol often collaborates with adjacent mobile radar projects, such as Doppler on Wheels and SMART-R . [ 2 ]
Mobile doppler weather radars have been used on dozens of scientific and academic research projects from their invention in the late 1900s. [1] One problems facing meteorological researchers was the fact that mesonets and other ground-based observation methods were being deployed too slow in order to accurately measure and study high-impact atmospheric phenomena.

Revised RaXPol analysis found winds of 302 ± 34 mph (486 ± 55 km/h) well above ground level and ≥291 mph (468 km/h) below 10 m (33 ft), with some subvortices moving at 175 mph (282 km/h). [26] The strongest winds occurred in small subvortices along the south side of the main vortex. The two most intense vortices occurred north and east of ...
This is officially the widest tornado to ever occur, with a width of 2.6 miles (4.2 km) at its peak. This is the width found by the National Weather Service based on preliminary data from University of Oklahoma RaXPol mobile radar that also sampled winds of 296 mph (476 km/h), which was used to upgrade the tornado to EF5.

Storm chasers and the RaXPol mobile research radar observed a brief satellite tornado rotating around the primary El Reno tornado; no damage was reported. [107] EF0 SSW of El Reno: Canadian: OK: 2313–2314 0.5 mi (0.80 km) 350 yd (320 m)
A prolonged and widespread tornado outbreak affected a large portion of the United States in late-May 2013 and early-June 2013. The outbreak was the result of a slow-moving but powerful storm system that produced several strong tornadoes across the Great Plains states, especially in Kansas and Oklahoma.
On the afternoon of May 21, 2024, a violent, destructive and powerful multi-vortex tornado struck the communities of Villisca, Nodaway, Brooks, Corning, and Greenfield in southwestern Iowa, killing five people and injuring 35 others.
The 2011 El Reno–Piedmont tornado was a long-tracked, deadly and extremely powerful EF5 tornado that struck central Oklahoma on the evening of May 24, 2011. The tornado impacted areas near or within the communities of El Reno, Piedmont, and Guthrie, killing nine and injuring 181.
