For more than 50 years, the National Hurricane Center has used the Saffir-Simpson Windscale to inform the risk of property damage; indicates a hurricane on a scale from Category 1 (wind speeds between 74-95 mph) to Category 5 (wind speeds of 158 mph or greater).
But as rising ocean temperatures contribute to increasingly intense and destructive hurricanes, climatologists Michael Wehner of the Lawrence Berkeley National Laboratory (Berkeley Lab) and James Kossin of the First Street Foundation questioned whether an open Category 5 is enough to signal a risk of hurricane damage in a warming climate.
So they reviewed and detailed their extensive research in a new paper published in Proceedings of the National Academy of Sciences ( PNAS ), where they also introduce a hypothetical Category 6 Saffir-Simpson Wind Scale that would include storms with wind speeds of . higher than 192 mph.
