In a 2018 paper, Kossin showed that the increase in tropical cyclones stalling is a global trend. The magnitude varies by region but is “generally consistent with expected changes in atmospheric circulation forced by anthropogenic emissions,” he wrote.

Rising global temperatures also influence storms in other ways: A warmer atmosphere holds more moisture, which means hurricanes can bring more rain, and warmer oceans provide additional energy that can make them stronger.

Hurricane Harvey dumped 60 inches of rain on parts of Texas in 2017 and stalled over the Houston area for days. Hurricane Florence stalled in 2018, flooding parts of coastal North Carolina. Kossin said Hurricane Sandy, in 2012, also took an unusual path that may have been affected by shifting global wind patterns, turning west and slamming into New Jersey instead of being carried eastward, out to sea and away from land, by prevailing westerly winds.
