Larger atmospheric rivers tend to occur within dense clusters of storms. And frequency and intensity increases with global warming. Yang Zhou Berkeley Lab

Added to the debate about a new hurricane category 6 there is now one on extending the official Atlantic hurricane season, as proposed by World Meteorological Organization in view of ever earlier storms!

Jeff Jeff Berardelli , indeed many print & broadcast meteorologists have missed the point of our cat 6 hurricane paper. However, Marshall Shepherd Dr. Marshall Shepherd has a editorial that makes it for us. forbes.com/sites/marshall…

Mega-hurricanes with wind speeds above 192 mph are becoming more and more common with climate change. As covered in The Guardian, a new paper with Michael Wehner Berkeley Lab as co-author suggests that we may need to create a Category 6 to describe them: theguardian.com/world/2024/feb…

Thanks Jeff Jeff Berardelli for the opportunity to clarify why we wrote this paper; to raise awareness about the dangers of climate change in hurricane prone regions (not to change hazard messaging when a storm is coming)

I try to explain on WCBS 880 why we introduced a hypothetical cat 6 hurricane category to highlight climate change danger and why a single number does not convey the danger of an impending storm Berkeley Lab omny.fm/shows/wcbsam-o…

2/2 We are also telling journalists that the National Hurricane Center's excellent products better inform the public about hazards than the Saffir-Simpson categories & encourage them to make use of such. Read the paper to understand that our messaging is about climate change only

1/2 Our message about the CAT6 paper is that climate change is making the strongest storms stronger. The SS scale can express the increasing danger of tropical cyclones in changing climate but a single number is clearly inadequate to convey the flood risks of an impending storm.

Adding a Category 6 to the scale that rates hurricanes could better describe storms with extremely fast wind speeds—which could increase in frequency as global temperatures rise, Nancy K. Walecki writes: theatlantic.com/science/archiv…

We introduce a hypothetical category 6 to the Saffir-Simpson Hurricane Wind Scale to convey the increased risk of very intense tropical storm due to climate change Berkeley Lab pnas.org/doi/10.1073/pn…
