The Next Hurricane Scale?

Guest: Dr. Jennifer Collins & Dr. Nadia Bloemendaal When it comes to hurricanes, we often rely on a familiar scale to understand their strength — categories based largely on wind speed. But anyone who’s experienced a storm knows that impacts go far beyond just how fast the winds are blowing. Today, we’re joined by Jennifer Collins and Nadia Bloemendaal, whose work is helping to rethink how we model and measure tropical cyclones. They’re the minds behind the STORM model, a powerful tool for simulating thousands of storms across the globe, and the developers of the Tropical Cyclone Severity Scale — a new way of looking at storm risk that goes beyond traditional categories. In this episode, we’ll explore how large-scale modeling is changing our understanding of hurricane risk, why current classification systems may fall short, and how new approaches could improve the way we communicate danger and prepare for future storms.
