As new scientific findings lead to consensus within the scientific community and engineering principles are thoroughly tested by damage observations and actual claims, a certain “critical mass” is reached in the model development process. AIR’s research and modeling team has spent over three years developing the upcoming release, even incorporating research published as recently as 2009. Of course, models must be judged by how they perform in the real world for real decision-makers—and incorporating significant changes while maintaining model stability is an enormous challenge. With that in mind, the AIR team is confident that the updated hurricane model is not only state-of-the-art, but will provide clients with a robust and accurate view of probabilistic risk for the entire spectrum of exposure and geography subject to U.S. hurricane risk.
