Wurman is particularly interested in researching tornadogenesis and amassing sufficient datasets of tornado structure and dynamics observations for tornado climatology study. He is also the discoverer of sub-kilometer hurricane boundary layer rolls, and wrote the pioneering papers on mapping tornado winds, multiple vortices, and other tornado-related phenomena. Joshua Wurman participated in both the VORTEX projects, doing early deployments of the first scraped together DOW radars for and served on the steering committee and was a principal investigator for , the field research phase of which occurred from 2009-2010. Wurman's team observed the top two fastest wind events and two contenders for the largest tornado circulations. He leads the ROTATE tornado observational project every spring and hurricane intercepts in the fall. A current major project of his is studying lake-effect snow in the OWLeS. Dr. Wurman has authored and co-authored many scientific publications relating to hurricane and tornado dynamics and weather radar technology including two articles in Science, articles in the Journal of the Atmospheric Sciences, Monthly Weather Review, Journal of Atmospheric and Oceanic Technology, Weather and Forecasting, and others. He was lead author of a controversial article in the Bulletin of the American Meteorological Society analyzing the potential impacts of a major tornado passing through urban areas. near Attica, Kansas
Radar innovations
Wurman and his team developed the DOW radars, a new concept of mobile radar, used to observe tornadoes, tropical cyclones, wildfires, winter storms, and other phenomena from close range. He built the first DOW in 1995 from spare parts from NCAR and other facilities and as of March 2014 has built eight DOW units. The success of the DOWs led to a revolution of mobile radars in severe storms and other meteorological field research. Furthermore, they developed meteorological bistatic radar multiple-Doppler networks, and the Rapid-Scan DOW, and holds about several patents related to bistatic and DOW technology. He founded BINET Inc., manufacturer of Bistatic Networks, in 1995.
Wurman has appeared in many television shows and his work, particularly with the DOWs, and is cited in numerous popular and technical books about weather. He is best known to the general public as the "scientist" in The Discovery Channel's reality series Storm Chasers, where he led a group of storm chasers conducting research during tornado season. CSWR worked with Sean Casey's Tornado Intercept Vehicle combining in situ intercept data and photogrammetry work with DOW remote sensing data. His scientific research style is often shown clashing with other chasers who are not government funded. He was also featured on National Geographic Channel's Tornado Intercept and The True Face of Hurricanes, as well as in the IMAX film Forces of Nature. He's also been seen in several other documentaries and shows including those on PBS' Nova and NewsHour, NHK, BBC, History Channel, and The Weather Channel, and on Dateline NBC, CBS' 48 Hours, Larry King Live, Nightline, and Good Morning America. Popular articles describing his work have appeared in Discover, Scientific American, New Scientist, The Economist, Biography, Newsweek, Time, FHM, Self, The New York Times, USA Today, The Washington Post, and many other publications.
