For the second year in a row, a team of over 100 scientists and dozens of vehicles will take to Tornado Alley in an attempt to study one of Mother Nature’s most destructive phenomena. Like last year, Colorado researchers will be helping with the project.
Among the Colorado-based participants are University of Colorado students and researchers. They join others from 11 other universities from across the nation including the University of Oklahoma, Penn State University, and the University of Massachusetts.
Perhaps most well known, Dr. Josh Wurman of the Center for Severe Weather Research (CSWR) in Boulder will be a key contributor. Watchers of the Discovery Channel’s Storm Chasers series know Wurman well as the operator of a Doppler On Wheels (DOW) radar truck and coordinator of the TV series’ storm chases.
Verification of the Origins of Rotation in Tornadoes Experiment 2 (VORTEX2) is simply the largest, most extensive in-field tornado study in history. Funded by the National Science Foundation (NSF) and the National Oceanic and Atmospheric Administration (NOAA), the VORTEX2 team will prowl the Great Plains hunting their elusive prey from May 1st to June 15th.
Once again, a veritable armada of scientific equipment will be deployed. Ten mobile radar units, dozens of vehicles, over 70 other instruments and even an Unmanned Aerial Vehicle (UAV) will cover thousands of miles on the Great Plains.

The scientists and researchers taking part in VORTEX2, the largest ever tornado field study, have been confounded by Mother Nature in their search for twisters. The Verification of Origin of Rotation in Tornadoes EXperiment2 (VORTEX2) and its accompanying 80 scientists and 40 vehicles have yet to track a tornado since the project launched just over a week ago.
The team has tracked severe weather systems from northwestern Texas to Oklahoma and while they have seen severe thunderstorms that produced significant rainfall and winds, twisters have eluded them thus far. While this is undoubtedly frustrating for the team, it has given them time to practice the coordination and deployment of the researchers.
Last Tuesday the team was on their first chase day in west Texas and was able to deploy their mobile radar units and mobile mesonet vehicles. That storm yielded little more than wind and hail but it provided a valuable opportunity to view their plan in action and highlight areas where improvement is needed.
VORTEX2 scientists are on the chase for tornadoes today in west Texas.
Since officially kicking off on Sunday, the weather has been less than cooperative for the VORTEX2 tornado field study teams. From their starting point in Oklahoma, there simply has not been severe weather worthy of them chasing. That is changing right at this moment as the team is on the road and headed to western Texas.
VORTEX2 (Verification of Origin of Rotation in Tornadoes EXperiment2) is nothing short of the most ambitious field study of tornadoes ever launched. Comprising a team of more than 80 scientists utilizing 40 vehicles, 10 mobile radar units and an Unmanned Aerial Vehicle (UAV) from the United States, Canada, Australia and Finland, the study hopes to answer many of the questions about twisters that we do not have answers to.
How do tornadoes form? What exactly causes the wind to spin into a concentrated funnel? How can we tell exactly when a tornado will form and when it will die, or how long it will last? Why do some thunderstorms produce tornadoes and others do not? What is the structure of tornadoes? What is the relationship of tornadic winds to damage?
The VORTEX2 tornado research project will be the largest in-field study of tornadoes ever.
The single largest and most ambitious field study to increase our understanding of tornadoes is set to kick off next month. The Verification of Origin of Rotation in Tornadoes EXperiment2 (VORTEX2 or V2) will feature more than 50 scientists utilizing 40 vehicles, 10 mobile radar units and an Unmanned Aerial Vehicle (UAV).
The study which will run from May 10 to June 13 will become the largest mobile in-field laboratory ever assembled to study tornadoes. In a statement Louis Wicker, research meteorologist with NOAA’s National Severe Storms Laboratory and V2 co-principal investigator said, “Data collected from V2 will help researchers understand how tornadoes form and how the large-scale environment of thunderstorms is related to tornado formation.”
The VORTEX2 tornado research project will be the largest in-field study of tornadoes ever.
Operations will be controlled at the National Weather Center in Norman, Oklahoma while the mobile units chase tornadoes across Tornado Alley and the central Great Plains. The target area for the study ranges from southern South Dakota through Nebraska, Kansas, Oklahoma and the Texas Panhandle. Eastern Colorado, home of many tornadoes, is included in the study.
This unprecedented gathering of scientists and technology hold incredible promise for the research that will be gathered. The original VORTEX program which happened from 1994 to 1995 documented the entire life cycle of a tornado from start to finish, the first time that had ever been done. That research greatly enhanced our understanding of twisters and led to much improved tornado warnings that help to save lives today.
VORTEX2 seeks to build on that research and the research that has taken place since. According to the project website it will seek to answer such important questions as: How do tornadoes form? What exactly causes the wind to spin into a concentrated funnel? How can we tell exactly when a tornado will form and when it will die, or how long it will last? Why do some thunderstorms produce tornadoes and others do not? What is the structure of tornadoes? What is the relationship of tornadic winds to damage?
An important finding from the original VORTEX experiment was that the factors responsible for causing tornadoes happen on smaller time and space scales than scientists had thought. New advances will allow for a more detailed sampling of a storm’s wind, temperature and moisture environment and lead to a better understanding of why tornadoes form – and how they can be more accurately predicted.

VORTEX2 features scientists and students from the United States, Canada and Australia in collaboration with government agencies, private industry and educational institutions. Many luminaries within the storm chasing and severe weather research community will participate including Dr. Josh Wurman of the Discovery Channel’s Storm Chasers TV show. Some of the notable participating organizations include Center for Severe Weather Research, Rasmussen Systems, NOAA National Severe Storms Laboratory, OU/NOAA Cooperative Institute for Mesoscale Meteorological Studies, NSF-sponsored National Centers for Atmospheric Research, Penn State University, University of Oklahoma, Texas Tech University, Lyndon State College, University of Colorado, Purdue University, North Carolina State University, University of Illinois, University of Massachusetts, University of Nebraska, Environment Canada, and the Australian Bureau of Meteorology.
