This study found that associated with a poleward shift of the subtropical jet in the North Pacific basin, the number of
atmospheric river days increases much more significantly in Alaska during spring because both increased moisture and increased wind speed gang up to increase the frequency of atmospheric rivers.
In one sentence: A strikingly large increase in the number of
atmospheric river days awaits the U.S. west coast if climate warming remains relatively unchecked, according to researchers from Pacific Northwest National Laboratory.
The fractional increase in
atmospheric river days falls between 50 % and 600 %, depending on the seasons and landfall locations.
Results: A strikingly large increase in the number of
atmospheric river days awaits the U.S. west coast if climate warming remains relatively unchecked.
In a warmer climate, the atmosphere can hold even more moisture, so it is not surprising that the number of
atmospheric river days will increase in the future.
However, it is unclear whether some areas will see larger increases in
atmospheric river days than others.
