Climate change is altering the conditions that lead to hurricane development. That’s made some meteorologists reconsider how we measure those storms.
Experts have used the Saffir-Simpson scale since 1969 to classify hurricanes by their wind speeds, ranging from Category 1 to Category 5.
Zachary Handlos, the director of Atmospheric and Oceanic Studies at Georgia Tech which is examining how forecasters currently classify and communicate storm threats, says each storm is different and could result in a range of consequences.
"There's storm surge […] there's inland flooding from the significant rainfall — that was the big thing with Helene last year in our area," he said, noting that previously, Hurricane Irma only brought sustained winds to the region.
"You can also get tornadoes within hurricanes too, so not only are you dealing with flooding, storm surge, you also have to deal with tornadoes in the area at the same time," Handlos said.
He said any new scale should be complementary to the Saffir-Simpson scale, not replace it, as researchers still rely on it for historical study and communication with the public.
