Summary
Hurricanes are rated on a scale from one to five, depending on their wind speeds. The higher the speed, the higher the category. But as climate change makes powerful storms more common, it may be necessary to add a sixth category, according to a new paper published by leading hurricane researchers.
The current five point scale, called the Saffir-Simpson scale, was introduced in the 1970s and is used by forecasters around the world including at the National Hurricane Center in Florida. Under the scale, storms with maximum wind speeds of 157 miles per hour or higher are designated as Category 5 hurricanes.
The authors of the new paper, James Kossin of the First Street Foundation and Michael Wehner of the Lawrence Berkeley National Laboratory, have been studying the effects of climate change on hurricanes for decades. They propose that Category 5 should include hurricanes with maximum sustained winds of 157 to 192 miles per hour, and that a new Category 6 should include any storm with wind speeds above 192 miles per hour.
