Hurricanes Harvey and Florence also stalled, leading to extreme rainfall. Research shows it’s a global trend. Recent research shows that more North Atlantic hurricanes have been stalling as Dorian did, leading to more extreme rainfall. How that slowing is connected to global warming is still an area of debate. There are different mechanisms at work in the tropics and mid-latitudes, but, “in the broadest sense, global warming makes the global atmospheric circulation slow down,” said NOAA hurricane expert Jim Kossin, co-author of the June study.
