OU Researchers Develop Radar Simulator to Characterize Scattering Mechanisms of Debris Particles in Tornadoes

A University of Oklahoma research team with the Advanced Radar Research Center has developed the first numerical polarimetric radar simulator to study and characterize scattering mechanisms of debris particles in tornadoes. Characterizing the debris field of a tornado is vital given flying debris cause most tornado fatalities. Tornado debris characteristics are poorly understood even though the upgrade of the nation’s radar network to dual polarimetric radar offers potentially valuable capabilities for improving tornado warnings and nowcasting.

“With this simulator, we can explain in great detail to the operational weather community the tornadic echo from the polarimetric radar,” said Robert Palmer, ARRC executive director. “The signal received by the dual polarimetric radar is not easily understood because rain is mixed with the debris. The knowledge we gain from this study will improve tornado detection and near real-time damage estimation.”

Numerous controlled anechoic chamber measurements of tornadic debris were conducted at the Radar Innovations Laboratory on the OU Research Campus to determine the scattering characteristics of several debris types—leaves, shingles and boards. Palmer, D.J. Bodine, B.L. Cheong, C.J. Fulton and S.M. Torres, the center, and the OU Schools of Electrical and Computer Engineering and Meteorology, developed the simulator to provide comparisons for actual polarimetric radar measurements.

Before this study, there were many unanswered questions related to tornado debris scattering, such as knowing how the size, concentration and shape of different debris types affect polarimetric variables. How the radar identifies the debris is equally as important. Orientation of debris makes a difference as well as how the debris falls through the atmosphere. Overall, understanding debris scattering characteristics aid in the discovery of the relationship between debris characteristics, such as losing and centrifuging, and tornado dynamics.

OU team members were responsible for various aspects of this study. Coordination of damage surveys and collection of debris samples were led by Bodine. Field experiments were designed by team members in collaboration with Howard Bluestein, OU School of Meteorology. Electromagnetic simulations and anechoic chamber experiments were led by Fulton. The signal processing algorithms were developed by Torres and his team. Cheong led the simulation development team.

The study, “SimRadar: A Polarimetric Radar Time-Series Simulator for Tornadic Debris Studies,” will be published in the May issue of the Institute of Electrical and Electronics Engineers Transactions on Geoscience and Remote Sensing. This work is supported by the National Science Foundation with grant number AGS-1303685. There were significant results from the collaboration between the center and the Disaster Prevention Research Institute in Kyoto University.

An animation has been developed for the simulation of the three types of tornadic debris used in this study, which included leaves (green), shingles (pink) and boards (orange). The OU team has the ability, however, to simulate other types of debris.

Vogel Selected as Director of Oklahoma Water Survey

The University of Oklahoma has selected Jason R. Vogel as the director of the Oklahoma Water Survey. Located on the University Research Campus, the Survey is the focal point and catalyst for OU’s expertise in research, outreach and education in water topics. The Survey’s mission is to study the state’s water resources and to collect, analyze, interpret and disseminate research-based information to industry professionals, researchers, students, teachers, citizens, governments and other organizations.

“We are very fortunate to have someone of Jason’s experience, energy, stature and vision joining the OU Family, especially at a time when water issues are of increasing importance to our State,” said Vice President for Research Kelvin Droegemeier. “The Oklahoma Water Survey, which he will lead, will play a major partnership role in a wide array of water issues that directly affect our citizens.”

In addition to his responsibilities as director of the Survey, Vogel will serve as associate professor in the OU School of Civil Engineering and Environmental Science. For more than 20 years, Vogel has worked to facilitate and develop solutions for water issues throughout the Great Plains. Prior to joining the Survey, Vogel held faculty and research positions at Oklahoma State University in the Department of Biosystems and Agricultural Engineering and the U.S. Geological Survey.

While at OSU, he developed an award-winning research and outreach program on stormwater and stream management and is recognized as one of the leading experts in low-impact development stormwater management systems in the region. In his role at OSU, Vogel presented and organized water-related educational programming to more than 10,000 individuals, including water-industry professionals, government officials, regulators, youth and the general public at more than 230 events.

Vogel has served the water sector in leadership positions and on committees at the national, state and local levels for a variety of groups, including the Water Environment Federation, the American Society of Civil Engineers, the American Society of Agricultural and Biological Engineers, the American Ecological Engineering Society, the Oklahoma Clean Lakes and Watersheds Association, the Disaster Resilience Network of Tulsa, the Green Country Sustainability Forum and the Stillwater Drainage Appeals Board.

Vogel begins his new position as director of the Oklahoma Water Survey on July 1, 2017. He and his wife, Stephanie, and twin daughters will be moving to Norman soon.

OU and Mercy Test New Models in Largest Breast Cancer Clinical Trial in Oklahoma

A University of Oklahoma and Mercy Hospital Oklahoma City research team is set to begin the largest breast cancer clinical trial ever performed in Oklahoma. The team has developed new breast cancer risk prediction models based on a computer-aided image feature analysis scheme to identify patients who might have cancers that are not visible on mammography. After review of 2,000 imaging studies performed at Mercy over the past two years and refinement of the image analysis system, the clinical trial begins July 1, 2017, at the Mercy Breast Center.

Bin Zheng and Hong Liu, professors in the Gallogly College of Engineering, affiliates of the Stephenson School of Biomedical Engineering and members of the Stephenson Cancer Center, teamed with Dr. Alan Hollingsworth, medical director of the Mercy Breast Center, to develop and validate this unique breast cancer risk model for identifying women who are excluded from current breast magnetic resonance imaging guidelines, but have a higher risk of developing mammography-occult or hidden cancers that can be detected by MRI. At the same time, the study will evaluate women with elevated lifetime cancer risk, but who are in no imminent risk of developing image-detectable cancers.

“The goal is to significantly increase cancer detection of breast MRI screenings based on the quantitative imaging markers rather than the existing epidemiology-based risk assessment approaches,” said Zheng.

Over the next three years, the clinical trial will enroll 4,000 women with mammograms interpreted as normal according to best practice guidelines. These mammograms will be de-identified and sent electronically to Zheng and Liu at the OU Advanced Cancer Imaging Laboratory for analysis. The women with higher scores predicted by the risk model will qualify for the additional breast screening. Hollingsworth anticipates between 200 and 400 patients of the original 4,000 will qualify for a breast MRI.

“If we can demonstrate cancer detection rates of even five percent in this population, then we will have achieved a higher yield than any other method of selecting patients for breast MRI screening. Five percent is 10-fold the cancer detection rate of screening mammography. At five percent or greater, we have the potential to alter how we screen for breast cancer. Unlike research projects that might take a decade or longer from ‘bench-to-bedside,’ if we’re successful, this study will have practice-changing implications,” said Hollingsworth.

Participants in this study will be those women who routinely have their mammograms performed at Mercy Breast Center. If you are interested in learning more about the clinical trial, call 405.936.5455.

The National Institutes of Health/National Cancer Institute funded this research with a five-year, $2.5 million grant.
