Tornadoes and Hail Storms

Insured losses from tornadoes and hailstorms are on the rise. Although mainly driven by increased population densities, large inter-seasonal variability in the activity of tornado seasons leads to the question of which climatic drivers trigger the active seasons.

Tornado and hail storm research is changing and it is the goal of RPI to explore new avenues of research resulting in improved model development.

RPI is sponsoring research from a leading scientist with the aim of significantly improving tornado and hailstorm risk estimations. Severe local storms are relatively small-scale atmospheric phenomena that can result in billions of dollars of tornado, hail, and wind damage each year. While the physics of these storms are fairly well understood, understanding why and how the frequency and locations of severe local storms change from year-to-year, and over longer time scales needs to be furthered. The Tornadoes, Hail Storms, and Climate project directly addresses these questions in a manner relevant to the (re)insurance industry.

    Tornadoes, Hail Storms, and Climate

    Among weather-related losses to the insurance industry, those owing to hail and tornadoes are significant, particularly in North America. This project offers new information on why severe local storms can cause billions of dollars in insured losses annually and shows the results of idealized model experiments that have been applied to the real-world climatology of severe local storms.
