The Impact of Vertical Wind Shear on Hail Growth in Simulated Supercell Storms

Hail

Research The increase in losses resulting from severe convective storms continues to outpace advances in detection, forecasting, and mitigation. Hailstorms account for a large percentage of these losses; however, research activities focused on improving the ability to detect, forecast, and mitigate against this hazard have lagged behind those for hurricanes and tornadoes. The rapid advancement…

Analysis of Hailstorm Frequency

Hail1 Comment

Research IBHS statisticians and engineers develop maps representing the frequency of hail reports in the United States. These maps illustrate the average number of reports per 100 square miles of hail greater than 1 inch.

Evaluating Radar-Based Hail Detection

Hail

Research This study reports on the accuracy and effectiveness of radar-based hail detection. Hail detection outputs from the National Weather Service (NWS) network of more than 150 Doppler radars form the backbone of many commercially available post-storm hail swath products. Comparisons with the ground-truth observations recorded during the IBHS hail field program are ideal for…

Leveraging CoCoRaHS Hailpad and Damage Observations

Hail1 Comment

Research IBHS analyzes data from the Community Collaborative Rain Hail and Snow (CoCoRaHS) measurement program to understand hailstorm characteristics. CoCoRaHS is a successful citizen scientist observation campaign that collects precipitation measurements to supplement conventional observations. IBHS collaborated with the National Center for Atmospheric Research (NCAR) and Colorado State University (CSU) to compile CoCoRaHS hailpad observations…
