Mighty hurricanes get mightier

These and other strong tropical cyclones have become more powerful in recent years.

Some of the world’s strongest storms, particularly North Atlantic hurricanes, have, on average, gained wind speed during the past three decades, thanks to a warming trend in many of the ocean basins where such storms are spawned.

New analyses reported in the Sept. 4 Nature indicate that in the strongest tropical cyclones — also known as hurricanes in the North Atlantic and typhoons in the North Pacific — peak wind speeds increased as much as 3 meters per second each decade from 1981 to 2006.
