Storm chasing is broadly defined as the deliberate pursuit of any severe weather phenomenon, regardless of motive, but most commonly for curiosity, adventure, scientific investigation, or for news or media coverage. A person who chases storms is known as a storm chaser or simply a chaser.
The Late-May 1998 tornado outbreak and derecho was a historic tornado outbreak and derecho that began on the afternoon of May 30 and extended throughout May 31, 1998, across a large portion of the northern half of the United States and southern Ontario from southeastern Montana east and southeastward to the Atlantic Ocean. The initial tornado outbreak, including the devastating Spencer tornado, hit southeast South Dakota on the evening of May 30. The Spencer tornado was the most destructive and the second-deadliest tornado in South Dakota history. A total of 13 people were killed; 7 by tornadoes and 6 by the derecho. Over two million people lost electrical power, some for up to 10 days.
Timothy Patrick Marshall is an American structural and forensic engineer as well as meteorologist, concentrating on damage analysis, particularly that from wind, hail, and other weather phenomena. He is also a pioneering storm chaser and was editor of Storm Track magazine.
Doppler on Wheels 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 affiliated with the University of Alabama Huntsville and led by Joshua Wurman, with the funding partially provided by the National Science Foundation (NSF), as part of the "Community Instruments and Facilities," (CIF) program. The DOW fleet and its associated Mobile Mesonets and deployable weather stations have been used throughout the United States since 1995, as well as occasionally in Europe and Southern America. The Doppler on Wheels network has deployed itself through hazardous and challenging weather to gather data and information that may be missed by conventional stationary radar systems.
Joshua Michael Aaron Ryder Wurman is an American atmospheric scientist and inventor noted for tornado, tropical cyclone, and weather radar research, the invention of DOW and bistatic radar multiple-Doppler networks.
Storm Chasers is an American documentary reality television series that premiered on October 17, 2007, on the Discovery Channel. Produced by Original Media, the program follows several teams of storm chasers as they attempt to intercept tornadoes in Tornado Alley in the United States. The show was canceled at the end of its 5th season by Discovery Communications on January 21, 2012.
The Verification of the Origins of Rotation in Tornadoes Experiment are field experiments that study tornadoes. VORTEX1 was the first time scientists completely researched the entire evolution of a tornado with an array of instrumentation, enabling a greater understanding of the processes involved with tornadogenesis. A violent tornado near Union City, Oklahoma was documented in its entirety by chasers of the Tornado Intercept Project (TIP) in 1973. Their visual observations led to advancement in understanding of tornado structure and life cycles.
Tony Laubach is an American storm chaser and meteorologist. He has participated in several field research projects and is one of the surviving members of TWISTEX. He has been contracted as a severe weather photojournalist for various major television networks, and has starred in several television shows, including Seasons 3 through 5 of Storm Chasers on the Discovery Channel.
TWISTEX was a tornado research experiment that was founded and led by Tim Samaras of Bennett, Colorado, US, that ended in the deaths of three researchers in the 2013 El Reno tornado. The experiment announced in 2015 that there were some plans for future operations, but no additional information has been announced since.
Reed Timmer is an American meteorologist and storm chaser. Born in Grand Rapids, Michigan, he took an interest in science, including weather, at a young age, before experiencing severe weather, including a hailstorm at age 13. After presenting weather forecasts at his high school, he began studying meteorology at the University of Oklahoma, completing his PhD in 2015.
Sean Cameron Casey is an American IMAX filmmaker and storm chaser who appeared in the Discovery Channel reality television series Storm Chasers. Casey created an IMAX film called Tornado Alley about chasing tornadoes and had to build the Tornado Intercept Vehicle (TIV) and the Tornado Intercept Vehicle 2 (TIV2) to film inside a tornado. Tornado Alley was released worldwide on March 18, 2011. Casey has been named one of the 50 best minds of 2008 by Discover Magazine.
The SRV Dominator is a series of tornado interceptors owned, operated, and maintained by meteorologist Reed Timmer, with funding partially provided by AccuWeather and the Discovery Channel. The Dominator Series consists of the Dominator 1, a modified 2007 Chevrolet Tahoe, the Dominator 2, a modified 2011 GMC Yukon XL, the Dominator 3, a modified 2012 Ford F-350 Super Duty, and Dominator Fore, a name utilized for three different Subaru Forester's, two of which have since been totaled.
David K. Hoadley is an American pioneer of storm chasing and the first widely recognized storm chaser, as well as the founder and former editor of Storm Track magazine. He is also a sketch artist and photographer.
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. Other strong tornadoes caused severe damage in Nebraska, Missouri, Illinois, and Michigan. The outbreak extended as far east as Upstate New York. 27 fatalities were reported in total, with nine resulting from tornadoes.
Timothy Michael Samaras was an American engineer and storm chaser best known for his field research on tornadoes and time on the Discovery Channel show Storm Chasers. He died in the 2013 El Reno tornado.
The 2013 El Reno tornado was an extremely large, powerful, and erratic tornado that occurred over rural areas of Central Oklahoma during the early evening of Friday, May 31, 2013. This rain-wrapped, multiple-vortex tornado was the widest tornado ever recorded and was part of a larger weather system that produced dozens of tornadoes over the preceding days. The tornado initially touched down at 6:03 p.m. Central Daylight Time (2303 UTC) about 8.3 miles (13.4 km) west-southwest of El Reno, rapidly growing in size and becoming more violent as it tracked through central portions of Canadian County. Remaining over mostly open terrain, the tornado did not impact many structures; however, measurements from mobile weather radars revealed extreme winds in excess of 313 mph (504 km/h) within the vortex. These are among the highest observed wind speeds on Earth, just slightly lower than the wind speeds of the 1999 Bridge Creek–Moore tornado. As it crossed U.S. 81, it had grown to a record-breaking width of 2.6 miles (4.2 km), beating the previous width record set in 2004. Turning northeastward, the tornado soon weakened. Upon crossing Interstate 40, the tornado dissipated around 6:43 p.m. CDT (2343 UTC), after tracking for 16.2 miles (26.1 km), it avoided affecting the more densely populated areas near and within the Oklahoma City metropolitan area.
Tornado Chasers is an American documentary series that premiered on September 19, 2012, on TVNweather.com. The program follows Reed Timmer and his team of storm chasers as they attempt to intercept tornadoes in Tornado Alley in the United States and Canada. Season 2, funded largely through a successful Kickstarter campaign, commenced on September 30, 2013. The series is a two-time Webby Award Honoree, once for Best Documentary Series in 2013, and again for Best Editing in 2014.
James M. Leonard, also known as "Cyclone Jim", was an American professional storm chaser, photographer, and videographer. Intercepting severe weather including thunderstorms, tornadoes, hurricanes and typhoons, he was among the earliest storm chasers. He was the first to photograph an anticyclonic tornado.
On May 9, 2016, a violent multi-vortex EF4 tornado struck southern Katie, Oklahoma. The tornado was extremely erratic and killed one person while causing $1,000,000 in damages. The tornado was extremely photogenic, and was heavily documented by storm chasers and civilians.
