The US National Center for Atmospheric Research is a US federally funded research and development center (FFRDC) managed by the nonprofit University Corporation for Atmospheric Research (UCAR) and funded by the National Science Foundation (NSF). NCAR has multiple facilities, including the I. M. Pei-designed Mesa Laboratory headquarters in Boulder, Colorado. Studies include meteorology, climate science, atmospheric chemistry, solar-terrestrial interactions, environmental and societal impacts.
Tornadogenesis is the process by which a tornado forms. There are many types of tornadoes and these vary in methods of formation. Despite ongoing scientific study and high-profile research projects such as VORTEX, tornadogenesis is a volatile process and the intricacies of many of the mechanisms of tornado formation are still poorly understood.
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 Illinois 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.
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.
Eric Michael Nguyen was an American professional storm chaser, meteorologist, and photographer from Keller, Texas, United States. In 2008, Nguyen released his first book of photography titled Adventures in Tornado Alley: The Storm Chasers with co-author Mike Hollingshead.
Howard Bruce Bluestein is a research meteorologist known for his mesoscale meteorology, severe weather, and radar research. He is a major participant in the VORTEX projects. A native of the Boston area, Dr. Bluestein received his Ph.D. in 1976 from MIT. He has been a professor of meteorology at the University of Oklahoma (OU) since 1976.
Roger M. Wakimoto is an atmospheric scientist specializing in research on mesoscale meteorology, particularly severe convective storms and radar meteorology. A former director of the National Center for Atmospheric Research (NCAR), Wakimoto in November 2012 was appointed as assistant director of the Directorate for Geosciences (GEO) of the National Science Foundation (NSF).
Erik Nels Rasmussen is an American meteorologist and leading expert on mesoscale meteorology, severe convective storms, forecasting of storms, and tornadogenesis. He was the field coordinator of the first of the VORTEX projects in 1994-1995 and a lead principal investigator for VORTEX2 from 2009-2010 and VORTEX-SE from 2016-2017, as well as involved in other smaller VORTEX offshoots and many field projects.
Paul M. Markowski is an American meteorologist and leading expert on tornadogenesis and the forecasting of supercells and tornadoes.
Louis John Wicker is an American atmospheric scientist with expertise in numerical analysis, numerical simulation, and forecasts of severe convection and tornadoes. Doing storm chasing field research, Wicker deployed the TOtable Tornado Observatory (TOTO) and was in leadership roles in the VORTEX projects. He is also known for pioneering work simulating convection at the National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana–Champaign (UIUC).
Jeffrey W. Frame is an American atmospheric scientist known for observational and modeling studies of severe convective storms and for teaching meteorology. He was a scientist for VORTEX2 and other field research programs.
Donald W. Burgess is an American meteorologist who has made important contributions to understanding of severe convective storms, particularly tornadoes, radar observations and techniques, as well as to training other meteorologists. He was a radar operator during the first organized storm chasing expeditions by the University of Oklahoma (OU) in the early 1970s and participated in both the VORTEX projects.
David C. Dowell is American atmospheric scientist recognized for research on tornado structure and dynamics and on tornadogenesis. He participated in both of the VORTEX projects.
Rebecca Suzanne Hornbrook is an atmospheric chemist at the National Center for Atmospheric Research (NCAR). She currently holds the position of Project Scientist II while also belonging to a variety of groups based out of NCAR, UCAR, and NASA. She is notable for her work as one of the leading experts in Volatile organic compounds (VOCs) while possessing an interest in air quality, biosphere-atmosphere interactions, chemical kinetics, and photochemistry.
Sonia Maria Kreidenweis is an American Professor of Atmospheric Sciences at Colorado State University. Her research considers aerosols and their impact on weather and the climate. She has previously served as President of the American Association for Aerosol Research and was a board member of the American Meteorological Society. She was elected a Fellow of the American Geophysical Union in 2019.
Emily V. Fischer is an atmospheric chemist and an associate professor in the department of atmospheric science at Colorado State University. She earned notoriety from her work on the WE-CAN project and on PAN, specifically its role in changing the distribution of oxidants in the troposphere. She has received many honors including the prestigious James B. Macelwane Medal which is "given annually to three to five early career scientists in recognition of their significant contributions to Earth and space science." Fischer is also a role model and activist in galvanizing support for women in STEM fields.
Tennessee Valley Weather is a television station owned by Tennessee Valley Media Group, headquartered in Lawrenceburg, Tennessee. It services North Alabama, Southern Tennessee, and Northeast Mississippi with daily weather updates and local severe weather information. The combined network broadcasts over-the-air updates, social media posts, and produces live content on a digital streaming television channel available on a host of Internet based platforms, as well as local cable providers.
The RapidX-bandPolarimetric Radar, commonly abbreviated as RaXPol, 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. Unlike its counterparts, RaXPol typically places emphasis on temporal resolution, and as such is capable of surveilling the entire local atmosphere in three dimensions in as little as 20 seconds, or a single level in less than 3 seconds.
Starting in the mid-1900s, mobile radar vehicles were being used for academic and military research. In the late 1900s, mobile doppler weather radars were designed and created with the goal to study atmospheric phenomena.
