Traditional parametric models cannot adequately capture the highly complex interactions between numerous atmospheric components that constitute winter storms. In different regions across the globe, winter storms manifest themselves differently, depending on the active climate conditions. Infinite Observations leverages Numerical Weather Prediction (NWP) technology that simulates storm systems by modelling atmospheric spatial and temporal dynamics using mathematical equations that govern fluid- and thermodynamics. A regional winter storm can manifest itself in the form of sub-perils such as a blizzard, ice storm, Nor’ easter, freezing rain, wind, storm surge, etc. or as a combination of sub-perils or a succession of sub-perils that constitute storms, clustering.  NWP allows for clustered events to be separated and identified correctly, one factor that is critical in determining economic and other types of losses.
