Texas Tech will be sending a team of 19 faculty and students to participate in the project, as well as two observing platforms to collect data on the tornadoes.
Texas Tech University wind researchers will take part in a collaborative nationwide project exploring the origins, structure and evolution of tornadoes.
The project, Verification of Rotation in Tornadoes Experiment 2 (VORTEX2 or V2) will occur from May 10 through June 13 in the central United States. The collaboration is the largest and most ambitious attempt to study tornadoes in history and will involve nearly 100 scientists and 40 research vehicles, including 10 mobile radars.
Christopher Weiss, assistant professor of atmospheric science at Texas Tech, will lead a team of 18 faculty and students into the field for the project. The assignment will last for two spring seasons.
“Data collected from V2 will help researchers understand how tornadoes form and how the large-scale environment of thunderstorms is related to tornado formation,” said Louis Wicker, research meteorologist with the National Oceanic and Atmospheric Administration’s (NOAA) National Severe Storms Laboratory and V2 co-principal investigator.
Texas Tech will bring two observing platforms to the VORTEX2 field phase. The first platform, named Stick-Net, represents an array of 24 durable tripoded observation stations, individually deployed in the path of tornado-producing storms to measure the temperature, pressure, humidity and wind. The second platform, one of the newly-constructed TTUKa mobile Doppler radars, will make remote measurements of the horizontal and vertical structure of tornado cyclones.
“When the project begins, we will travel wherever conditions are most favorable for tornadoes, anywhere from Texas to South Dakota,” Weiss said. “We will generally have a feel for regions of interest the day before the event, but will not have a specific target until the morning of the potential event.”
Scientists will sample the environment of supercell thunderstorms – violent thunderstorms capable of producing damaging winds, large hail and tornadoes – that form over more than 900 miles of the central Great Plains. Areas of focus include southern South Dakota, western Iowa, eastern Colorado, Nebraska, Kansas, the Texas panhandle and western Oklahoma. The V2 Operations Center will be at the National Weather Center in Norman, Okla.
V2 is a $10.5 million program funded by NOAA and the National Science Foundation, 10 universities and three non-profit organizations.
The original VORTEX program, operated in the central Great Plains during 1994 and 1995, documented the entire life cycle of a tornado for the first time in history. Recent improvements in National Weather Service severe weather warning statistics may be partly due to the application of VORTEX findings. V2 will build on the progress made during VORTEX and further improve tornado warnings and short-term severe weather forecasts.
Other scientists and students throughout the United States, Canada, and Australia that will work with the V2 program include the 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, 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.
Preliminary results from V2 are scheduled for presentation at Penn State University during fall 2009. At that time, organizers will begin planning details of the second phase of V2 scheduled for May 1 - June 15, 2010.
The Wind Science and Engineering (WISE) Research Center at Texas Tech University was established in 1970 and is focused on research, education and information outreach.
The Center offers interdisciplinary education in wind science engineering as well as develops information on windstorm disaster relief and other wind-related subjects for professionals and the public.
The program offers a Master of Science in Atmospheric Science. In addition, courses in Atmospheric Science are offered at the undergraduate level as well as a minor in Atmospheric Science.
