Severe Thunderstorm Risk Models

Our models’ daily thunderstorm simulators capture both large outbreaks and smaller events that have a significant cumulative impact on your bottom line.

A comprehensive, detailed view of severe thunderstorm risk

As severe thunderstorms continue incurring annual industry losses, we continue making scientific and modeling advancements to give you a complete view of risk.

Understand the impacts of all three sub-perils

Identify the frequency, severity, and geographical distribution of the separate tornadoes, hailstorms, and straight-line wind events.

Capture large and small loss-causing events

Get statistical and physical modeling integrated with the latest meteorological research and claims data accounting for all loss-causing events, large or small.

Differentiate vulnerability across regions

Evaluate the implications on loss of different construction materials, occupancy classes, building codes, structure age, and mitigation features.

Get in-depth analysis of severe thunderstorm risk

Insight into highly localized events

Events close in space and time are grouped using clustering algorithms to create realistic individual outbreak patterns of hailstorms and straight-line winds in each location.

Innovative vulnerability frameworks

Our Severe Thunderstorm Risk Models account for regional and temporal variations in sub-peril vulnerability to capture local building practices and characteristics.

Extensive component validation

Each component has been extensively validated against detailed claims data, damage surveys, engineering research, historical events, and industry experience.
