Tropical cyclones, including hurricanes and typhoons, are now crawling across the planet at a slower pace than they did decades ago, dragging out and amplifying their devastation, new research published Wednesday shows.

At the same time, related research published just last month suggests that warming temperatures from climate change will slow storms more in the future.

While having a cyclone travel with less speed may seem like a good thing, it’s actually just the opposite. Wind speeds within the storm remain high, but the whole system itself moves slower across the landscape, allowing punishing rains to linger longer over communities.
