Another ensemble of models shows a 35 percent increase in the number of days with
landfalling atmospheric rivers in western North America.

landfalling atmospheric rivers over the North Pacific in thirty years of MERRA reanalysis.

landfalling atmospheric rivers over the west coast of North America, J. Geophys.
Researchers charge global warming with projected significant increases in the frequency of both extreme precipitation and
landfalling atmospheric rivers

landfalling atmospheric river frequency and extreme precipitation over western North America from the Large Ensemble CESM simulations.

They compared two simulations, present and future, of
atmospheric rivers determined from the vertically integrated water vapor flux to quantify the changes in
atmospheric rivers that make
landfall over western North America.
The fractional increase in
atmospheric river days falls between 50 % and 600 %, depending on the seasons and
landfall locations.
From Oct. 1 to March 31, 45
atmospheric river storms made
landfall along the West Coast, the Center for Western Weather and Water Extremes reported.
Additionally, many
atmospheric river storms move down the coast over time, so those that made
landfall above California frequently moved down to the state as well.
The spatial extent, intensity and location of
atmospheric river (AR)
landfall are well reproduced by the RCMs, as is the fraction of winter rainfall from AR days.
