The research conducted by Dr. Joshua Soderholm and Ph.D. candidate Yuzhu Lin sheds light on the significant impact of using real hailstones in storm modeling. Traditionally, scientific modeling of hail has assumed that hailstones are perfectly spherical. However, as Dr. Soderholm points out, hailstones can take on various shapes such as oblong, flat disks, or even with spikes coming out, making each hailstone unique.
According to lead researcher Yuzhu Lin, the differences in storm modeling outcomes when using more naturally shaped hailstones were dramatic. The pathways through the storm, growth patterns, landing locations, speed, and impact of the hailstones on the ground all varied significantly. This groundbreaking approach to modeling hailstones has not been done before, making it an exciting scientific discovery.
Dr. Soderholm emphasizes the importance of building a comprehensive ‘hailstone library’ to enhance the accuracy of hailstorm simulations. By using data from 217 hail samples, which were 3D scanned and sliced in half, researchers are able to better understand how hailstones form and the variations in their shapes and structures. This data is now part of a global library aimed at creating a clear picture of hailstone diversity.
The research not only benefits scientists studying storms but also has significant potential in real-time hail prediction. Dr. Soderholm highlights the potential of more accurate forecasts in warning the public about hailstorms, enabling them to stay safe and reduce damage. Industries such as insurance, agriculture, and solar farming, which are sensitive to hail, could also benefit greatly from improved forecasting techniques.
The groundbreaking research conducted by Dr. Joshua Soderholm and Yuzhu Lin highlights the importance of considering the variability in hailstone shapes in storm modeling. By using real hailstones and building a comprehensive ‘hailstone library,’ researchers are paving the way for more accurate and impactful storm predictions. The potential applications of this research extend beyond the scientific community to benefit public safety and various industries sensitive to hailstorms.
