Major thunderstorms can last for several days at time and have an impact across multiple countries or states. However, the individual constituents of an outbreak of such a thunderstorm, tornadoes, hailstorms, and straight winds, are often very localised and last just minutes. To capture the losses from both the large and small effects Infinite Observations employs a high-resolution granular damage mapping for each specific sub-peril, based on satellite and radar data from meteorological organisation in North America, Europe and Australia along with advanced clustering analyses techniques. This yields models with exceedance probability curves that can be used to determine losses resulting from large outbreak and smaller events. (Weighed) damage functions are generated by the model for each specific sub-peril, which include factors such as gust wind velocity, impact energy, construction types, building codes, seasonality, etc. The models can be validated in its entirety or model component can be validate independently against information and research from industry sources.
