SUCCESSFUL IBHS HAIL FIELD STUDY YIELDS VALUABLE DATA Understanding hail and hailstorms requires more than just developing theories about these phenomena. At some point, researchers have to go where these natural events occur to gather the evidence needed to test those hypotheses. A pair of research teams from the Insurance Institute for Business & Home Safety did just that this spring. Carefully tracking tornadoes and violent, severe thunderstorms for many days, the teams completed a unique and highly successful hail field study as a part of the Institute’s multi-faceted hail research effort. Dr. Tanya Brown, IBHS research engineer and occupant of the South Carolina Wind and Hail Underwriting Association Junior Chair in Research, and Dr. Ian Giammanco, IBHS research scientist, led two separate deployments to the Central Plains region of the U.S. in May and June, driving thousands of miles to measure the mass, dimensions, and compressive strength of hundreds of hailstones produced by supercell thunderstorms. These valuable data on hailstone characteristics will be used in research projects at the IBHS Research Center, so that scientists can gain a clearer understanding of how hail damages various building materials, as well as how to significantly improve risk modeling and weather forecasts.
