Is It Time to Scrap the Saffir-Simpson Hurricane Rating Scale?

MIT Tropical Expert: “The Saffir-Simpson scale is deeply deficient and should be discarded.” Science evolves over time. Our understanding of the natural world improves as new technology comes online, leveraging more granular, reliable, repeatable data sets. The science of meteorology, like every other science, is a moving target. The Fujita tornado rating scale was upgraded and enhanced in 2006 to better reflect observed wind damage. NOAA is launching WSSI, the Winter Storm Severity Index, a new, experimental winter storm rating scale with five categories. Sound familiar? Is it time to rethink the Saffir-Simpson rating scale for hurricanes, which only predicts...

Rapid Ocean Warming Poses New Challenges for Tropical Cyclone Prediction

Better Hurricane Forecasts Will Require Near-Real-Time, Deep Ocean Monitoring “How many more eyewall replacement cycles before landfall? Let me check the latest real-time, deep ocean temperature anomalies first”. This scenario may not be as far-fetched as it sounds. Recent studies confirm warming of the world’s oceans is taking place faster than previously estimated; as much as 40% faster than the United Nations estimated in 2015. The implications of warming seas include stronger and more rapidly-intensifying hurricanes and more extreme rainfall amounts. Research confirms roughly 93% of the additional warming from man-made greenhouse gases is going into the world’s oceans. Climate...
